Description
AGF Manufacturing Model 7000L and 7200L pressure relief valves comply with the requirements of NFPA 13 that stipulates a pressure relief valve must be installed on all wet fire sprinkler systems downstream of any pressure reducing valve. Both models relieve excess system pressure caused by surges or temperature changes. They include a bronze body and stainless-steel spring housed in a plastic casing that allows the user to temporarily lock it out to perform hydrostatic testing without removing the valve from the system.
