Back pressure/relief valves

Chemline Plastics has launched its SB Series back pressure/relief valves in solid plastics and stainless steel. They are designed for long maintenance-free life on chemical dosing lines 1/4in to 4in and offer reliable openings and adjustable relief pressures of 3 to 150psi. The advanced hydraulic design offers high flow rates, low hysteresis, and low overpressure to fully open. The all-plastic construction (PVC, PP or PVDF) offers high chemical resistance. True union end connections up to 2in eliminate leakage problems common with old-fashioned threaded body valves.
