AGF Manufacturing has introduced two new lockable pressure relief valves — Model 7000L and Model 7200L. These models can be temporarily locked closed to allow for hydrostatic testing without removing the pressure relief valve from the system. They can be ordered standalone or as part of AGF’s products that include pressure relief. The new pressure relief valves include two metal tabs: “flush” and “hydro.” The “flush” tab can be lifted to quickly flush debris from the valve or, using a standard flow switch hex key, temporarily lock the valve open to allow draining through the relief valve. The “hydro” tab can use the same hex key to temporarily lock the valve closed for hydrostatic testing with the valve installed in the system.
