AP20-D Modular Relief Valve

The AP20-D modular relief valve is used to maintain constant pressure in a line by releasing excess pressure to atmosphere. While similar to the relief function in a standard regulator, the AP20-D is capable of relieving pressure spikes more quickly.

  • Compatible with AC20-D assemblies
  • Uses AR20-D accessories: mounting bracket, set nut, gauges
  • Optional built in silencer
