YTC valve positioners and I/P converters
YTC is the South Korean manufacturer of smart and electro-pneumatic valve positioners that A.N Trader has long supplied for critical process control applications. Rotork acquired YTC and the range now trades as Rotork YTC — see our Rotork brand page for actuators and the wider positioner line.
This page focuses on the YTC positioner and I/P converter range in depth, including the air filter regulators that complete a pneumatic control loop: smart positioners with HART communication, electro-pneumatic positioners for linear and rotary actuators, I/P converters for 4-20mA to pneumatic signal conversion, and filter regulators that condition plant air supply ahead of the positioner.

Product Categories
Air Filter Regulators
Filter regulators that drop the plant's main air supply to a stable working pressure and strip particulates out before the air reaches a positioner or other pneumatic device. 5-micron filtration, with an optional relief function.
Electro-Pneumatic Positioners
Analogue positioners that convert a DC 4 to 20mA control signal into the pneumatic output needed to drive a linear or rotary valve actuator. The Rotork YTC YT-1000 and YT-1050 families sit here.
I/P Converters
Current-to-pressure converters that turn a 4~20mA DC control-room signal into a proportional 0.02~0.1 MPa pneumatic output for a pneumatic positioner or control device.
Pneumatics
Compressed-air equipment for valve control and linear motion — positioners, I/P converters, filter regulators and cylinders. Everything in this group runs on clean, regulated plant air.
Positioners
Devices that hold a control valve at exactly the position its 4-20mA command signal asks for, comparing the demand against mechanical stem feedback. Covers both analogue electro-pneumatic units and microprocessor-based smart positioners.
