Signal Lock Valve
Signal Lock Valve
The SLV-30 Signal Lock Valve is designed to prevent any instrument signal loss from affecting actuator positioning. In the event of instrument signal failure, the SLV-30 will maintain the last position of the control valve and positioner. The SLV-30 can be factory installed or easily retrofit to most existing pneumatic actuator/positioner models, and is compatible with all pneumatic controllers and I/P transducers.
