The Simtech PBP Series Pressure Bypass Valve is a 3-port valve designed to relieve excess fluid pressure in piping systems. When mounted in-line, the pressure by-pass valve will permit fluid to pass through the system. When the fluid pressure approaches the valve setting, the excess fluid is vented through the bottom port.  Adjustable screw and lock-nut make it easy to accurately pre-set relief pressure from 10 to 80 psi.
