Relief Valve PL-4" set at 13.0 PSI

Connection: 4" NPT

Manufacturer Part Number: 909831040420

The operation of the relief valve is simple. As the service line air pressure reaches pressure setting, the weight loaded cap is forced upwards off the valve seat. As pressure increases, the cap rises to expose the discharge ports. The valve automatically reseats itself as line pressure is reduced.
