Features
- The pop-off valve plays a crucial role as a secondary pressure relief valve.
- This pop-off valve has a brass body and NBR O-rings.
- It is designed to work together with a primary pressure regulating valve, such as a pressure regulator or unloader valve.
- The pop-off valve should be set to open at approximately 200 PSI above the primary pressure control valve’s adjusted pressure.
- In the event of a primary valve failure, this secondary valve will bypass fluid to protect the operator’s safety and the integrity of the high-pressure pumping system.
