Single acting also: 5 L/min (N) or less at 280 kPa, 6 L/min (N) or less at 500 kPa. Double acting: 10 L/min (N) or less at 400 kPa. AVP300/301 are 4-20 mA (no HART/SFN), AVP302 is HART. SS2-AVP300-0100, 41st edition July 2024.

Single acting also: 4.0 L/min [N] or less at 280 kPa, 4.8 L/min [N] or less at 500 kPa. Double acting: 8 L/min (N) or less at 400 kPa with balanced output at 70 % of supply. There is no model 'AVP700': AVP701/702 = HART (SS2-AVP702-0100), AVP703 = FOUNDATION fieldbus (SS2-AVP703-0100-16, https://www.azbil.com/products/factory/download/catalog-spec/SS2-AVP703-0100-16.pdf), identical figures.

Standard range (3-9, 9-15, 3-15, 3-27, 6-30, 1-17 psig). High Output range (2-60, 3-120 psig): 0.07 scfm (1.98 NL/min) midrange typical. Row label reads 'Max. Air Consumption' but the value is qualified 'midrange typical'. Flow rate (not bleed) 4.5 scfm @ 25 psig supply.

Standard range. High Output range (2-60, 2-100 psig): 4.5 scfh (2.25 Nl/min) at mid range typical. Footnote: 'Zero-based units have slightly higher air consumption.' The sheet's own metric conversion (0.75 Nl/min) is slightly higher than 1.5 x 0.472. Flow capacity (not bleed) 4.5 scfm @ 25 psig.

Explosion-proof. Prose on the same sheet says 'consuming only .05 scfm (1.42 Nl/min)'. 'Multiply by 1.29 for Natural Gas'. Flow capacity (not bleed) 4.5 scfm @ 25 psig, 12 scfm @ 100 psig.

Standard range (3-15, 3-27, 6-30 psig). High Output (2-60, 3-120 psig): 4.2 scfh (2.1 NL/min); Zero-Based (0-30, 0-60, 0-120): 6.0 scfh (3 NL/min). From the controlair.com IOM (441-622-052 REV 03/24/2020); the distributor-hosted spec sheet P/N 441-625-033 gives the same 1.8 scfh (0.05 m3/hr). Flow capacity (not bleed) 4.5 scfm @ 25 psig.

Open-loop, non-relay I/P: consumption is a constant bleed. 'Flow Capacity 2.4 scfm max'.

Open-loop I/P; the sheet states 'Flow Capacity: Same as Air Consumption'. Consumption rises with supply: 4.94 scfh (2.33 L/min) @ 85 psig, 8.36 scfh (3.95 L/min) @ 150 psig.

Recorded 1.9 SCFH at 9 psig (mid-scale) set point; 2.5 SCFH at 15 psig full scale, 4.2 SCFH at 30 psig. With natural-gas media 1.3/2.5/3.2/5.4 SCFH.

Recorded 7.0 SCFH at 9 psig (mid-scale) set point; 9.5 SCFH at 15 psig full scale, 13.5 SCFH at 30 psig. Extended range 0-30 psig: 3.1/7.8/11.8 SCFH at 0/15/30 psig; 0-60: 1.6-13.3 SCFH; 0-120: 0.5-15.1 SCFH. The explosion-proof TXI7800 brochure quotes much lower figures (see fairchild-txi7800). Flow rate (not bleed) 2.5 SCFM @ 25 psig supply.

Recorded the 3-15 psig standard-range figure (5.0 SCFH). Extended range: 12.0 / 13.0 / 17.0 SCFH for 0-30 / 0-60 / 0-120 psig. Flow rate (not bleed) 2.5 SCFM @ 25 psig supply, 9.0 SCFM @ 120 psig.

High-flow I/P with integral volume booster (output capacity 15 SCFM @ 20 psig supply, not bleed). Supply spec is 20 +/- 2 psig. T5221 is the same family.

Standard relay, single-acting direct relay. Double-acting relay at 5.5 bar / 80 psig: less than 1.3 normal m3/hr / 49 scfh (23.1 L/min). Low-bleed relay (Instruction Manual D103605X012, Mar 2026): average 0.056 normal m3/hr / 2.1 scfh at 20 psig (0.99 L/min), 6.9 scfh at 80 psig. Converted from the scfh figure; the Nm3/hr figure gives 6.33 L/min.

Single-acting direct relay. Double-acting relay at 5.5 bar (80 psig): less than 1.3 normal m3/hr (49 scfh) (23.1 L/min). Low-bleed relay: average 0.056 normal m3/hr (2.1 scfh) at 20 psig (0.99 L/min). Identical figures in Bulletin 62.1:DVC6000 D102758X012 (Feb 2008, distributor copy at escventura.com). Nm3/hr figure gives 6.33 L/min.

Nearest figure to 20 psig; quoted at 22 psig with the low-pressure relay. High-pressure relay (3.4-7.0 bar) at 4 bar / 58 psig: 0.12 normal m3/h / 4.4 scfh (2.08 L/min). Same figures in Instruction Manual D103176X012 (Aug 2025). Nm3/h figure gives 1.00 L/min.

Also 2.0 bar (30 psig): 0.48 normal m3/hr (18.0 scfh) = 8.50 L/min; 2.4 bar (35 psig): 0.54 normal m3/hr (20.0 scfh) = 9.44 L/min. Single-acting. Bulletin number is D200062X012. Nm3/hr figure gives 6.33 L/min.

3582 pneumatic positioner plus 582i I/P converter. Also 2.0 bar (30 psig): 0.57 normal m3/hr (21.4 scfh) = 10.10 L/min; 2.4 bar (35 psig): 0.64 normal m3/hr (23.8 scfh) = 11.23 L/min. Single-acting. Nm3/hr figure gives 7.67 L/min.

Single-acting rotary positioner. High-pressure variant 3610JP: 0.64 normal m3/hour (24 scfh) at 6.9 bar (100 psig) = 11.33 L/min. Same figures in Instruction Manual D200149X012 (June 2022). Nm3/hr figure gives 6.67 L/min.

3610J plus 3622 I/P converter. Instruction Manual D200149X012 (June 2022) prints 18.2 scfh for the same 0.49 normal m3/hour. High-pressure variant 3620JP: 0.93 normal m3/hour (35 scfh) at 6.9 bar (100 psig) = 16.5 L/min. Nm3/hr figure gives 8.17 L/min.

Bulletin footnote: air consumption at a gain setting of 1/2 turn. Also 0.22 normal m3/hour (7.9 scfh) at 2.4 bar (35 psig) = 3.73 L/min. Single-acting.

Bulletin footnote: air consumption at a gain setting of 1/2 turn. Also 0.33 normal m3/hour (12.3 scfh) at 2.4 bar (35 psig) = 5.81 L/min. Single-acting. Nm3/hr figure gives 4.00 L/min.

Only one supply pressure quoted. Bulletin footnote defines m3/hr as normal m3/hr (0 C, 1.01325 bar). Bulletin number is D102127X012; the April 2020 edition (distributor copy) gives the identical figure. Converted from 12 scfh; the rounded 0.3 Nm3/hr would give 5.00 L/min.

Bulletin tabulates by output pressure; its footnote defines the average flow at 12 mA and 0.6 bar (9 psig) output, so that row is recorded. At 20 psig supply the range over 3-15 psig output is 0.04-0.07 m3/hr (1.5-2.6 scfh) = 0.71-1.23 L/min; at 2.4 bar (35 psig) supply, 6-30 psig output: 1.7-4.1 scfh. Bulletin number is D103197X012; identical table in Instruction Manual D103198X012 (Oct 2022). Emerson-hosted copies were unreachable, so a distributor copy is cited.

Only figure published; supply range 30-150 psig, so nothing nearer 1.4 bar. Air capacity 12 SCFM @ 60 psi is delivery, not bleed. Same value in the Logix 3000 Series brochure FCD LGENBR3000-00; the older Logix 3200IQ technical bulletin FCD LGENTB0058-02 gives 'Air consumption at 60 psig (4 barg) <=0.35 SCFM (0.5 Nm3/hr)'.

FOUNDATION Fieldbus sibling of the 3200MD; identical figure.

Double-acting standard relay 0.3 SCFM @ 60 psi; double-acting low-bleed relay 0.075 SCFM @ 60 psi = 2.12 L/min. IOM FCD LGENIM0112-11 04/26 Table 14 additionally gives the standard double-acting relay as 0.297 Nm3/h @ 1.5 bar (0.175 SCFM @ 22 psi) = 4.95 L/min and 0.51 Nm3/h @ 4.1 bar. Minimum supply 1.5 bar (22 psi). Optional zero-bleed package claims zero steady-state emissions.

Piezo pilot with 'zero bleed' relay; no supply pressure attached to the figure. Air delivery 350 nl/min (12 scfm) is not the bleed.

Single- and double-acting identical (0.120 Nm3/h @ 6 bar each). Supply range 1.5-6 bar; no lower-pressure figure. IOM not hosted on flowserve.com (product pages 404); read a distributor copy of FCD PNENIM0020-04-A5 06/22 and cross-checked an older D20/D22 IOM copy (valve.co.za) with the same figure.

Spool-valve positioner; supply range 1.4-8 bar (20-115 psi) but the figure is only given at 6 bar. Air delivery up to 45.6 Nm3/h at 6 bar is not the bleed.

Legacy product (spec PS0002 (AC-15) dated 11/00, Accord Controls, a unit of Flowserve); superseded by Apex 7000. Only a distributor-hosted copy of the product specification exists; Flowserve's own Apex 5000 IOM has no consumption figure. 3-15 psi input; Apex 5100 I/P module adds 4-20 mA.

'Automax' is Flowserve's valve-automation brand, not a positioner model; its positioners are the Apex series, and the Apex 7000 is the current Automax pneumatic positioner. 3-15 psi input (I/P transducer optional for 4-20 mA); max supply 150 psi; air capacity 9.6 SCFM std / 18 SCFM high @ 60 psi is delivery, not bleed. No figure nearer 1.4 bar published.

Table gives single acting 80/130/220 ln/h (2.8/4.6/7.8 scfh) at 1.4/3/6 bar; double acting 130/230/430 ln/h (2.17 L/min at 1.4 bar); spool-valve amplifier version 100/240/500 ln/h (1.67 L/min at 1.4 bar). Official Schneider copy PSS EVE0105 (also coded FD-PSS-PO-02-EN, 12/2020); identical table in the 04.2017 PSS EVE0105 distributor copy.

Same table as SRD991: single acting 80/130/220 ln/h at 1.4/3/6 bar; double acting 130/230/430 ln/h (2.17 L/min at 1.4 bar); spool valve 100/240/500 ln/h (1.67 L/min at 1.4 bar). The SRD960 PSS is EVE0109; se.com returns 404 for it, so a distributor-hosted copy was used (identical to the 07.2015 copy at disai.net).

Open-loop I/P and E/P. Recorded the 0.2-1 bar (3-15 psi) figure; 4.0 Nl/min for the 2 bar (3-27 psi) range. An older Watson Smith 100X sheet (coulton.com copy) quoted '1.4 l/min (0.06 scfm) typical'; the current IMI sheet is used. Flow capacity (not bleed) >300 Nl/min.

Closed-loop electronic I/P with enclosed bleed port. Flow capacity (not bleed) up to 300 NL/min.

Captured-bleed electronic I/P. 422 I.S. datasheet (en 6.6.365, 4/15) gives the same 0,4 Nl/min. Flow capacity (not bleed) up to 300 Nl/min (250 Nl/min for I.S.).

Applies to General Purpose, High Relief and Explosion Proof versions; Extended Range version is 0.07 SCFM (2.0 SLPM). Minimum flow rate (not bleed) 12 SCFM at 100 psig supply.

Same figure for NEMA 1 / 3R / 4X versions; catalog's own conversion is 2 LPM.

Zero-based version: 18 SCFH @ maximum output pressure (8.50 L/min). Flow @ mid range (not bleed) 6.5 SCFM @ 120 psig supply.

Piezo-ceramic I/P. Flow (not bleed) 15 SCFM (423 LPM) for 3-15 psig range.

Single-acting, standard relay; 30 psi is the lowest supply tabulated (supply range 20-100 psi). Brochure table: single-acting 0.282 scfm (8 l/m) @ 60 psi, 0.424 scfm (12 l/m) @ 90 psi; double-acting 0.424 scfm (12 l/m) @ 30 psi, 0.565 @ 60, 0.847 @ 90, 1.06 scfm @ 120 psi. IOM BHMN-SVI2AP-IOM-19681Z-0823 Table 24 states 0.2 scf/min (5.7 L/min) at 30 psi (same figure, rounded); high-flow relay 0.28 scf/min at 30 psi.

Also 3.4 SLPM (7.2 SCFH) @ 45 psi. Single-acting standard relay; no separate double-acting bleed figure published. Supply range 1.4-8.3 bar (20-120 psi). Same figures in IOM BHMN-SVI3-IOM-34587H-0626 Table 15.

Same figure for 4700P and 4700E. 4800P/4800E: 0.9 Nm3/h at 1.7 barg. IOM BHMN-4700-4800-P-E-IOM-19515J-0625 Table 6 states 'Maximum Air Consumption 0.3 scf/min - 25 psig supply (4700)' (= 8.5 L/min). Output/exhaust capacity 13.5 Nm3/h at 4.1 barg is delivery, not bleed.

Not an I/P transducer despite the Baker Hughes web-page title: the document is '8012/8013 Series Electro-pneumatic Valve Positioners' (force-balance cam positioner, 4-20 mA in). Table also gives 0.55 st.m3/h (0.33 Scfm) at 2.4 bar (35 psi) and 0.85 st.m3/h (0.51 Scfm) at 5.2 bar (75 psi). Max air output (steady state) 4.5 st.m3/h at 1.4 bar is delivery, not bleed. The 8013 IOM BHMN-8013-IOM-33469B contains no consumption figure.

Spool valve 6: < 1.0 Nm3/h / 0.6 scfm (16.7 L/min). No figure at 1.4 bar although the supply range is 1.4-8 bar. Same figures repeated in IMO 7ND9071EN 9/2026 (https://www.valmet.com/globalassets/sharepoint/imported/7nd9071en.pdf). Current bulletin number is 7ND9021EN (supersedes 7ND20EN).

Older documents give an upper bound instead: Operating Instructions A5E03436620-AF (09/2020), manual A5E00074631-06 and the FI 01 2010/2018 catalogs state 'Auxiliary power consumption in the controlled state < 3.6 x 10^-2 Nm³/h (0.158 USgpm)' = 0.60 L/min max. Siemens flyer PIFL-00171-0723 quotes 0.006 SCFM (= 0.17 L/min). Optional PS2 booster module adds 'Air consumption 1.2 x 10^-2 Nm3/h (0.007 SCFM)' = 0.20 L/min. Also available as PROFIBUS PA / FOUNDATION Fieldbus.

Order number is 6DR71.. Same figure as SIPART PS2; Siemens flyer PIFL-00171-0723 quotes 0.006 SCFM steady state for PS2 and PS100. Leakage actuator chamber (positioner portion) < 6 x 10^-4 Nm³/h.

Figure is in the service manual SD77 Rev. 26 (March 2013), section 1.2 General Specifications, and applies to the whole Model Series 77 (77-3, 77-3A, 77-8, 77-16, 77-40); the 77/771 catalog page (12-081622) states only 'Output Capacity Standard: 0.16 scfm' and no consumption figure. Normal supply 20 psig (30 psig for 3-27 psig output models).

lpm from 0.20 scfm; the datasheet's own 0.32 Nm3/h equals 5.33 L/min. Double-acting cylinder: Maximum Air Consumption 0.62 SCFM (1.0 Nm3/h) at 400 kPa. FOUNDATION fieldbus only. GS 16th edition Apr. 2016; product listed as discontinued on yokogawa.com/us.
