MEC Full Port 3 in. FPT Angle Valve

All Marshall Excelsior globe and angle valves are designed to withstand extreme temperatures. To increase the longevity of the seal, all Marshall Excelsior globe and angle valves have a 360 rotating seal that stops rotating when it contacts the sealing surface while the valve continues to be tightened. These valves are mainly used in piping systems to control liquid or vapor ow in bulk plants, bobtails, transports, pumps or compressors. Installation Note: Before installing a globe or angle valve, the piping system and container must be free of dirt, debris, foreign matter and other particles, large or small, that could damage the sealing surface or seal of the valve. A minimal amount of pipe sealant should be used on the mating part. Excess pipe sealant can also cause damage to the seal surface or seal. Damage to the sealing surface or the seal will cause the valve to leak. To avoid damage to the valve or piping, due to pressure build-up from temperature changes, a hydrostatic relief valve should be installed where liquid can be trapped between 2 shutoff valves. A vent valve should be installed on the downstream side of the globe or angle valve if the angle valve is used as a shutoff valve at the end of a loading hose. This allows the operator to vent the trapped liquid before disconnect.|All stainless steel internal components with rotating seat disc design and V-cup Teflon packing stem seals|Double lead acme stem thread ensures quick and efficient operation|Rated for 400 WOG|Operating temperature 40 to +212 degree F
