▼ Product Overview
The electric valve positioner YT-1000R is a device that receives a 420mA DC current signal from a controller or control system and delivers air to a pneumatic actuator to control the valve opening.
▼ Features
①There is no resonance phenomenon in the range of 5~200Hz.
② Direct action, reverse action, single action and double action can be easily switched.
③ The vibration generated by small actuators can be solved by adding a throttle hole in the positioner.
④Low air consumption and good economy.
⑤ Split-range control within the 1/2 range can be achieved without replacing parts.
