Brass Pressure Regulator, 3/4" 700PSI

TeeJet - 681534700 - 3/4 in. 700 PSI Brass Relief Valve

The TeeJet 681534700 (6815-3/4-700) is a piston-type pressure relief/regulating valve designed to bypass excess liquid and help maintain stable line pressure in high-pressure spray and liquid handling systems. Built from brass with a 3/4" inlet and pipe connection, it is adjustable to control line pressure anywhere within its operating range, with the selected setting secured by a locknut. Extra-large internal passages help it handle large flow volumes efficiently.
