Smart valve positioner, flameproof explosion-proof Exd, angular stroke, single acting, failsafe, split body anti-high temperature vibration
The high-end model C41 of the TORLEO series intelligent valve positioner can be equipped with a partial stroke test (PST) function. Partial Stroke Testing PST (Partial Stroke Testing) is suitable for ESD control valves with safety functions. By allowing the ESD control valve to partially close 10~30% of the stroke from the fully open position, periodic actions are set at certain time intervals, so as to pass the Monitor the movement of the valve position to determine whether its action state is normal, so as to ensure that the operation designation of the safety instrumented system (SIS) is accurately implemented on the ESD control valve, to solve the problem of "not moving at ordinary times, but not moving during use" and achieve functional safety. production requirements.
