Pop-Off Valves

Industrial Duty Pop-Off Valves for Reliable Secondary Pressure Relief
Pop-off Valves

The pop-off valve is a secondary safety relief valve. If the primary pressure control device fails to bypass set system pressure, the pop-off valve opens, allowing liquid to flow freely. A pop-off valve can save costly pump and system damage, and more importantly, it’s an added safety feature to protect those working around the equipment.
