Often used with catalysts, pH buffers, and electroplating solutions, these valves have a PVC body and an EPDM seal for excellent chemical resistance. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Adjust the set pressure within the range. Valves have a port for attaching a pressure gauge.

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.

A plastic body and fluoroelastomer seal stand up to harsh chemicals. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.
