APPLICATIONS: For discharge of liquid or gas from vessels, separators, treaters, knockouts and other similar liquid accumulators. For back pressure or pressure reducing applications with pressure pilots. FEATURES: Compact design O Ring sealed seat Valve travel indicator Field reversible topworks Teflon packed stuffing box TOPWORKS: Standard topworks have an effective diaphragm area of approximately 30 square inches for 1" and 65 square inches for 2" motor valves. Unless otherwise specified, all HPMV's will be furnished with ductile topworks, steel topworks available. Specify when ordering. SPRINGS: The 1"HPMV springs are available for diaphragm pressures of 10, 20, and 30 psig. The 2"HPMV springs are available for diaphragm pressures of 15, 20, and 30 psig. Unless otherwise specified, all 1" HPMV's with 1/2" INNER VALVES get 30 lbs. spring others get 20 lb. spring, all 2" HPMV's will be furnished with springs as follows 1000 & 2000 lb. W.P. valves, 20 lb. springs and 4000 lb. W.P. valves, 30 lb. springs. Top Adjusting Screw may be adjusted to vary the spring tension slightly; this affects pressure required to actuate valve. STEM TRAVEL: 1" HPMV - 1/2" maximum 2" HPMV - 3/4" maximum ACTUATOR WORKING PRESSURE: 10-30 psig normal (see spring ranges) 45 psig maximum WORKING PRESSURE: 1" HPMV - 4000 psig 2" HPMV - 1000, 2000 & 4000 psig INNER VALVE SIZES: 1" HPMV - 1/8",3/16", 1/4", 3/8", & 1/2" 2" HPMV - 1/4", 3/8", 1/2", 3/4" & 1" 2" HPMV - 7/16", 5/8" & 7/8" *Equal Percentage requires Pt. No. 2132 Diaphragm Plate on 1 In HPMV INNER VALVE SPECIFICATIONS: The 1" HPMV standard valve plugs consists of a carbide ball rigidly connected to a 303 stainless steel stem. Standard seats are made of heat treated tool steel. The 2" HPMV standard valve plugs for 1/2" and smaller consist of a carbide ball rigidly connected to a 303 stainless steel stem. Standard valve plugs for 3/4" and 1" consist of a hardened high chrome alloy ball rigidly connected to a 303 stainless steel stem. Standard seats are made of heat treated tool steel. Inner valves can be made from a wide selection of materials. Specify when ordering. 產(chǎn)品列表
