Gas pressure controller Pressuretrol®

The L4079A,B, and W PressureTrol® Limit Controls are high pressure limit switches that break electrical circuits when pressure rises to a preset value. The L4079A and B can be used with steam, air, noncombustible gases, and fluids noncorrosive to the sensing element. L4079W is for use on oil burner systems. Features & Benefits: L4079A has two ganged spst switches; breaks two circuits (may be both sides of the power supply) simultaneously L4079B has one spst switch L4079W is the same as L4079B but has seals for oil applications MICRO SWITCH® snap-acting switches are visible through transparent cover Switches open automatically but must be reset manually Trip-free reset mechanisms do not permit the limiting role of the PressureTrol® Control to be defeated by jamming the reset lever Control does not need leveling The L4079 is unaffected by moderate vibration
