Application Specifically designed to ensure positive shut-off and long, maintenance free service life in liquid or vapor service on bulk storage containers, transports, bobtails, cylinder filling plants and plant piping. The high quality construction and wide variety of sizes make them highly suited for use with LP-Gas, anhydrous ammonia and in the chemical and petrochemical industries. Features • “V”-ring spring-loaded pressure stem seal provides for leak-proof operation. No packing to retighten or replace. • Circular bridge in the globe design and a dropped seat in the angle design achieve greater flow with less pressure drop. • Swivel seat disc assembly minimizes the seat disc from grinding on the body seat. The seat disc stops rotating as soon as it touches the body seat. This feature provides for good seat alignment and ensures long seat life. • V” F. NPT plugged boss on the downstream side of the valve body allows attachment of a hydrostatic relief valve or vent valve. • “V”-ring stem seal virtually eliminates hard to turn handles frequently encountered with packed type seals. • Heavy duty rolled ACME stem threads provide quick action and long service life. Part Number * * 300# ANSI R.F. Flange. * * * To obtain approximate flow at other than 1 PSIG pressure drop, multiply flow in chart by square root of pressure drop. Example: 7514FP @ 9 PSIG = 133 x 9 = 399 GPM/propane. For NH3 flow, multiple propane flow by .90.

General Information Globe and Angle Valves, incorporating the synthetic rubber flange seal design, operate on the same principle as the “V”-ring valves. Gas pressure in the valve is exerted against the synthetic rubber flange, forcing it tightly against the stem. Leak-tight performance is assured and periodic adjustment is not required. The synthetic rubber construction provides smooth operating performance with long service life. These valves all incorporate a plugged %” NPT side boss on the downstream side of the valve that can be equipped with a hydrostatic relief valve or vent valve....
