Safety
ESD (Emergency Shutdown) and Partial Stroke Testing
Jan 10 2008
Samsonâs (Germany) Type 37303 Electropneumatic Positioner, which has also been enhanced to include an ESD function, has been designed to perform partial stroke tests on the valve. The combination of certified components and positioner functions meets all the necessary safety requirements. The positioner can be mounted on the valve in addition to the solenoid valve or to replace it. It allows the valve to be moved precisely to follow the set point within the valveâs working range. The partial stroke test completely integrated into the positioner detects a sticking valve caused, for example, by corrosion. Test schedules are made flexible and can be prolonged, if necessary. The required test validation can be performed simply by using the corresponding instrumentation and initiating it over a commonly available SIS logic solver.
