About Pressure-Relief Valves
More
Compact Pressure-Relief Valves
Due to their small size, these valves are often installed on tanks in low-clearance areas. They begin opening at the set pressure. Nylon valves fully open at about 10% over the set pressure and steel valves fully open at about 50% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. All have a vent outlet to exhaust discharge directly. Set pressure is not adjustable.
Nylon valves have better corrosion resistance than steel valves. They are color coded based on the set pressure for easy identification.

Pressure-Relief Valves with Push-to-Connect Fittings for Air
- For Use With: Air
- Temperature Range: 26° to 255° F
For a low-pressure seal around plastic and soft metal tubing, these valves have push-to-connect fittings. They allow inline flow from the inlet to the outlet during normal conditions and divert flow to the relief port in overpressure conditions. The relief port begins opening at the set pressure and fully opens at about 10% over the set pressure. It begins closing as pressure drops and fully closes when the system pressure is restored below the set pressure. The vented relief port exhausts discharge directly. Set pressure is not adjustable. Valves are color coded based on the set pressure for easy identification.
