The R-K 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 the fluid is vented through the bottom port. Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure. Wide working pressure range (10 to 80 PSIG) Top entry for easy in-line maintenance and can be factory pre-set upon request. It is ideal for DI water and other highly purity piping systems as well as most harsh chemicals and corrosives. No metal contact with fluid Note:This valve is not designed to be used in piping systems with back-pressure on the downstram side.
