Self-contained control system
Cameron LEDEEN SCCS self-contained control systems provide reliable valve shutdown when a reliable external power source is unavailable. The complete system consists of a linear or quarter-turn hydraulic spring return actuator with a self-contained control.
When using a hand pump with various control components, a zero-leakage circuit is maintained to ensure that valve movement does not inadvertently occur until a fail-safe signal is received. Controls are typically pilot tripped, but solenoids also can be used for remote control where electricity is available. The control must be reset manually after a fail-safe operation has occurred.
