YTC Type Valve Positioner

YT1000L Electro Pneumatic Valve Positioner-Blue

YT-1000L in blue — the most common private-label finish

A blue-housing YT-1000L built for buyers whose valve range is colour-coded. Electrically and mechanically it is the standard linear positioner: 4–20 mA input, cam feedback, 10–150 mm stroke.

Blue housing finish, produced in batch runs for private-label orders
Cam feedback link — changing the cam changes the secondary-loop gain
Works with single-acting (spring return) and double-acting actuators
Linearity ±1 % F.S. single acting, ±2 % F.S. double acting
PT (NPT) 1/4 air connection, PF 1/2 (G1/2) conduit

Technical background

Type YT-1000L Electro-pneumatic valve positioner is used for operation of pneumatic linear valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.

YT1000L Electro Pneumatic Valve Positioner- The main function of the YT electro-pneumatic positioner Pneumatic valve positioner and pneumatic actuator together constitute an automatic control unit and various regulating valve connections, after debugging and installation, are combined into a pneumatic regulating valve. Used in various industrial automation process control fields.

Adapted varieties Commonly used actuators are divided into pneumatic actuators and electric actuators, which can be divided into straight travel and angular travel. It is used to open and close all kinds of valves, wind panels, etc. automatically or manually. No

Questions buyers ask

What minimum quantity applies to a colour run?

Colour batches are quoted per order — send the model, colour and quantity by WhatsApp or email and the factory will confirm.

Does the blue finish change the temperature rating?

No. Operating temperature stays -20 to +70 °C, -20 to +60 °C for the explosion-proof build.
