About Pressure-Relief Valves

For Use With: Potassium Sulfate, Sodium Hypochlorite
Temperature Range: 0° to 140° F

With a three-port design, these valves allow inline flow from the inlet to the outlet during normal conditions and divert flow through the relief port in overpressure conditions. Often used with feed pumps for fertilizers and bleach, they have a PVC body and a PTFE seal for excellent chemical resistance. 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, resuming inline flow from the inlet to the outlet. Adjust the set pressure within the range.
