Smart valve positioner, angular stroke, double acting, failsafe, split body anti-high temperature vibration
Positioner partial stroke test (PST) function C41 high-end model, with built-in partial stroke test (PST) function. This function is to make the ESD valve partially close 10~30% of the stroke from the fully open position, and set periodic actions according to a certain time interval, so as to better check the movement of the valve rod and judge whether the working state of its function is normal, so as to ensure that the operation designation of the safety instrument system (SIS) is accurately implemented on the ESD (emergency shutdown valve) valve, without "Refusal" and meet the requirements of safe production.
