AGF Introduces Lockable Pressure Relief Valves to Expedite Hydrostatic Testing

MALVERN, PA —AGF Manufacturing is excited to introduce two new lockable pressure relief valves, Model 7000L and Model 7200L specifically designed for the fire sprinkler industry. These models can be temporarily locked closed to allow for hydrostatic testing without removing the pressure relief valve from the system, saving significant time during installation. 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. The “hydro” tab can use the same hex wrench 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.

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. Both come standard at 175 PSI. Model 7000L is also available with ratings of 200, 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 their pressure relief kits.
