globe angle valve - 1

“V”-Ring Seal Globe and Angle Valves General Information RegO® Globe and Angle Valves are designed and manufactured especially to meet the rigid requirements of the LP-Gas industry. The high quality construction and wide variety of sizes and styles also make them highly suited to many other industries such as anhydrous ammonia, chemical and petrochemical. These ductile iron valves are available in both threaded and flanged connections. Threaded connections are available in 1⁄2” F. NPT to 3” F. NPT sizes. Flanged connections are available in 11⁄2”, 2” and 3” pipe sizes. The ductile iron used in these valves has a 60,000 PSIG tensile strength which closely approaches that of steel castings. Its yield strength of 45,000 PSIG and elongation of 15% is also comparable to that of steel castings. These material features assure the ability of the valve body to withstand impact, wrenching stresses and thermal shock. This ductile iron conforms to ASTM specification A395. RegO® globe and angle valves are designed for working pressures up to 400 PSIG WOG and for operating temperatures from -40° F. to +160° F. “V”-Ring Stem Seal located above the seal, keeps the seal free from grit, and/or other foreign material that may hamper operation. Installation and Operation Note Containers and pipe lines should be thoroughly cleaned before globe and angle valves are installed. Large particles of solid foreign matter can permanently damage the seating surface in the valve body, causing the valve to leak. Use a minimum amount of a suitable pipe dope on the male connecting threads as excess amounts may fall off and be carried into the valve, causing damage to the seat or other operating parts. It is totally unnecessary to use excess force in opening or closing RegO® valves. The type of seat disc material used and the general design of these valves permits them to be opened and closed easily. Proper valve operation insures unusually long life. Wrenches must never be used to operate valves equipped with handwheels and designed for hand operation. Downstream Accessory Boss These RegO® valves incorporate a plugged 1⁄4” F. NPT boss on the downstream side of the body for attaching either a hydrostatic relief valve or vent valve. Boss size on the 2” and 3” valves has been increased to allow a 3⁄4” drilling for accommodation of a standard bypass valve or jumper lines. The “V”-ring spring-loaded pressure seal used in these RegO® globe and angle valves is the most effective stem seal yet developed. It should not be confused with conventional valve stem packing where the seal is obtained by compressing the packing around the stem by means of a packing gland with resultant hard operation and frequent packing replacement. The wax like surface of the teflon “V”-ring seal and consequent low friction assures leak-tight performance for an indefinite period where periodic retightening of the packing is not required and the seal provides extra long service life. In the RegO® “V”-ring design, the seal is effected by the pressure expanding the “V”-shape of the seal, forcing it against the stem and bonnet surfaces to prevent leakage. The higher the pressure within the valve, the more effective the seal becomes. A spring loaded washer under the “V”-rings keeps them in an expanded position to assure an effective seal under low pressure conditions. A wiper ring, Hydrostatic Relief—When the design of the piping installation is such that liquid may be locked between two shut-off valves, a hydrostatic relief valve should be installed in the lines between the valves. The pressures which can develop due to temperature increase in a liquid-full line are tremendous and can easily damage the valves or piping unless a hydrostatic relief valve is installed. Vent Valve—If the globe or angle valve is used as a shut-off valve on a loading hose, a vent valve should be installed in the downstream boss to allow liquid trapped beyond the shut-off valve to be vented before disconnecting the hose coupling. Replace Gate Valves with Flanged Valves Except for standard flange sizes, RegO® Flanged Globe and Angle Valves are smaller and lighter than contemporary valves, thus reducing price and shipping costs and making them far easier to install. RegO® face to face flange dimensions conform to gate valve dimensions, making replacement of most gate or plug valves with RegO® valves simple and easy. General Features Heavy Duty Handwheel provides easy operation. O-Ring Wiper keeps sand and grit away from pressure seal and stem threads. Heavy Duty ACME Threads for quick action and smooth operation. Swivel Seat Holder promotes long life. Synthetic Rubber Seat assures easy, positive shut-off. Globe & Angle Valves Teflon “V”-Ring Spring-Loaded Pressure Seal for leak-proof operation. No packing to adjust or replace. Stainless Steel Stem is centerless ground to provide a smooth sealing surface. Rugged Ductile Iron Body won’t crack or fracture from wrenching, dropping or hammer blows. Circular Bridge is contoured to provide extra high capacity and low pressure drop.
