    Adjustable Pressure-Relief Valves for Chemicals

    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.
