test valves without interference from the processing chain 2010-11-25
Partial Stroke Test is a common practice in factories processing many industry valves can be tested in the production process without major disruptions or downtime.
Valves, usually activated by a solenoid valve in a safety loop, the device allows operators preferred is the process of completing the emergency lines.
As part of its main wafer check valves, positioners and accessories, offers a series of controls Electro Samson stroke position can be tested without interrupting the production line will be. For example, the type of positioner 3730-3 contains ESD (emergency shutdown) to allow a test run without stopping the production line will be. Can be mounted on the side of the throttle valve, or replace the valve and can move at exactly the set of valves in the employment relationship forward. The partial stroke test is completely integrated into the positioner to the valve sticking, caused for example by corrosion.
Test plans can be as flexible as necessary and expand if necessary, adjusted to the needs of specific applications, while the validation tests can simply use the appropriate tools and initiating are performed using a standard SIS logic solver.
