| PRESSURE REGULATING VALVE DIRECT ACTING, SPOOL TYPE WITH RELIEVING FEATURE. ■ Maximum pressure setting up to 150 bar 2175 psi. ■ Three pressure ranges available for more accurate pressure control. ■ Partial reverse flow capability. ■ Hardened working parts for maximum durability. ■ Adjustable and tamperproof versions available. operation The adjustable spring-loaded spool is shifted at valve setting by the regulated outlet pressure on port [3] metering the supply flow from port [2], maintaining the regulated pressure on port [3]. An increase in the regulated pressure causes the spool to lift further and acts as a service line relief valve, closing the supply port [2] and then relieving to port [1]. Ports [2] and [3] remain normally open when port [3] pressure is below the valve setting. Back pressure on port [1] adds to the valve setting. | m / m | ||||||||||||||||
