The standard longneck body provides full clearance for 2-inches of insulation with ANSI 150 pipe flanges. STEM/DISC Stern design provides high strength and positive disc control with standardized end connection for operator interchangeability. STEM BEARINGS Bearings are standard on both the upper and lower shaft to minimize torque and provide maximum stern support. SEAT Molded-in resilient seat provides bubble-tight shutoff to 250 psi. Dead-End Service The lugged body is drilled and tapped for isolation and removal of downstream piping at full rated pressure. TESTING Each valve is individually tested for bubble-tight closure at 110% of full rated pressure 格林奈爾蝶閥GRINNELL蝶閥WCG空壓機(jī)專用蝶閥 GRINNELL蝶閥 GRINNELL 美國GRINNELL蝶閥 GRINNELL WCG DN80蝶閥 GRINNELL DN100蝶閥 GRINNELL DN150蝶閥 WCG DN65蝶閥 WCG DN100蝶閥 WCG DN150蝶閥 GRINNELL蝶閥真空機(jī)專用 干燥機(jī)專用GRINNELL蝶閥 干燥機(jī)上專用蝶閥GRINNELL WCG蝶閥 格林奈爾WCG空壓機(jī)專用閥門 現(xiàn)貨WCG真空機(jī)蝶閥 現(xiàn)貨WCG干燥機(jī)閥門 GRINNELL WCG蝶閥 真空爐設(shè)備上專用。GRINNELL WC光桿蝶閥
