AGF Manufacturing introduces 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.
Types of Metal tabs in valves
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. This feature will allow a sprinkler system or a TESTANDRAIN valve with relief valve and drain trim to be completely installed prior to initial system leak testing, greatly speeding up installation.
Pressure relief kits
AGF’s Model 7000L has a ½” MIPT inlet and FIPT outlet. Model 7200L has a ¾” MIPT inlet and FIPT outlet. Both are made with a bronze body and stainless-steel spring and are available with “ratings” of 175, 225, or 300 PSI.
AGF’s Model 7000L and Model 7200L can be ordered standalone, as part of select AGF TESTANDRAIN or RISERPACK assemblies, or part of their pressure relief kits.
