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.
