NLB Series No Lube Pressure Bypass Valve
The Simtech NLB Series Pressure Bypass Valve is a 3-port valve designed to relieve excess fluid pressure in high purity applications where lubrication is not permitted. When mounted in-line, the pressure by-pass valve will permit fluid to pass through the system. When pressure approaches the valve setting, fluid is vented through the bottom port. Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure. Note: This valve is not designed to be used in piping systems with back-pressure on the downstream side.
