Abstract: A relief valve provides pressure relief when a fluid line exceeds a predetermined pressure. The valve includes a body which defines a cavity between inlet and outlet flowpaths. The valve includes a lever arm, which pivots around a pivot point as the valve changes between open and closed positions. A plunger assembly is disposed in the cavity and seals the cavity from the inlet and outlet flowpaths in the closed position. Fluid pressure from the inlet flow path causes the plunger assembly to contact the lever arm to urge the lever arm to rotate. The lever arm engages a spring at a further distance from the pivot point than the plunger assembly, the spring resisting pivoting of the lever arm and urging the valve to remain in the closed position unless a predetermined pressure is exceeded.

Abstract: A terminal fixture is provided for installation at the end of each sprinkler head drop in a fire protection system. The terminal fixture is an automatic valve device that operates in response to the installation or removal of a sprinkler head from the fixture itself. When the sprinkler head is removed the terminal valve operates to close the end of the sprinkler drop feed line to prevent flow of fire protection fluid by preventing an open system. When a sprinkler head is reinstalled into the valve, the valve plunger is automatically displaced to an open position to restore full and unobstructed flow to the sprinkler head returning the drop to full and operable status. In this manner, no manual valves are added to the system which would prevent failsafe operation thereof.
