Plastic Valves

SB Series Plastic Back Pressure / Relief Valves. As a back pressure valve, installed in-line downstream of a pump, the back pressure below the metering pump is maintained. When installed in the branch of a tee the valve is a pressure relief valve. The valve stays closed until inlet pressure reaches the set pressure which is adjusted by turning the spring tensioning bolt. Inlet pressure acts upward against the piston allowing excess pressure to flow upwards through the orifice.

SB10 BACK PRESSURE RELIEF VALVE
SB 10 Series

SB10 Series Back Pressure / Relief Valves. For clean fluids with setting pressures from 3 psi to 60 psi. Select range in PVC, CPVC, Polypropylene or PVDF bodies. The SB 10 Series is very sensitive to pressure changes and requires low overpressure to open fully.

PW Wafer Check Valves This wafer check does not require a separate spacer or flange gaskets. The large orifice and full flow design means low pressure drop. Spring assisted disc closure is standard as well as an optical indication of disc open/close position.
