6 in Pneumatic Sliding Valve, 316 Stainless Steel, Threaded Pipe x ANSI Flange
Product Overview
The Betts pneumatic sliding valve is an external self-closing stop valve designed without a shear section. It requires 90 psi line pressure to fully open, with an air-open and spring-close cylinder. PTFE encapsulated O-rings ensure a positive seal for pressure or vacuum service, while standard 316 stainless steel discs provide premium corrosion resistance. The adjustable packing nut with woven PTFE-infused packing allows easy stem adjustments. The air cylinder operates up to a maximum working temperature of 250 °F (121 °C). A fusible plug set to melt above 212 °F (100 °C) is installed in the air cylinder to release air pressure in case of fire. The cargo tank must provide suitable protection for the valve as specified in 49 CFR 178.345-8.Sliding Valve, Air Cylinder Actuated Handle, Threaded Pipe Inlet, ANSI Flange Outlet, Pneumatic, 316 Stainless Steel, PTFE Seal, 316 Stainless Steel Stem, 6 in Inlet, 6 in Outlet, 90 psi Pressure Rating, 49 CFR 178.345-8 Standards, 250 °F Temperature Rating, 9.07 in Width
