1986 VALVE EQUIPMENT GUIDE Valves, valve actuators, and oth- er accessories are vital components in any ship's piping systems for cargo, fuel, ballast, steam, seawa- ter, and many other applications. Valve manufacturers offer a wide variety of valve types, variations, and materials, including ball, but- terfly, check, swing, gate, globe, di- aphragm, and other designs. They are produced in many materials, including bronze, stainless and car- bon steels, cast iron, aluminum, ductile iron, and in special materi- als for exotic requirements. The editors of MR/EN asked the manufacturers of shipboard valves and accessories to tell us about their latest products and marketing plans. The following review is based on the replies we had received at press time. FOR MORE INFORMATION If you wish to receive additional information on any of the products described in this review, circle the appropriate reader service number under each company's name, using the postage-paid card bound near the back of this issue. AMERICAN PIPING Circle 30 on Reader Service Card The forged steel line blinds man- ufactured by American Piping Products, Inc. of New Hyde Park, N.Y., are said to be the most posi- tive dead-tight shutoffs ever de- vised. These blinds feature "0" ring seals in dove-tailed grooves, specta- cle plates to indicate open or closed position, and lubricated jack bolts to automatically spread flanges apart. American line blinds are available butt weld or flanged, for all pressures and body materials. CLA-VAL Circle 31 on Reader Service Card Cla-Val Company of Newport Beach, Calif., manufactures a com- plete line of fluid-actuated, auto- matic fire protection equipment, from main valves down to the sprinklers. All components are de- signed to work together as a system for compatibility; they are also rug- ged and reliable. Designers of U.S. Navy ships have specified Cla-Val valves for more than 40 years. The company is said to be the Navy's largest supplier of automatic control valves for fire protection systems today. The Cla-Val magazine sprinkler valve has simple, dependable dia- phragm actuation, and features a test fitting and a double "0" ring stem. The manual pilot valve con- trol changes valve position quickly; it is used for magazine sprinkler valves and void filling valves. Cla- Val's dual solenoid pilot control valve is used to activate magazine sprinkler and foam systems, or any- where a relatively large capacity so- lenoid valve is needed. This valve stays in either position until the opposing solenoid is energized. CRAWFORD Circle 32 on Reader Service Card Crawford Fitting Company of So- lon, Ohio, manufactures Swagelok® tube fittings whose unique swaging action provides a seal between fer- rule and body at a point different from where the heavy work is per- formed. It supports the tube ahead of the seal to resist vibration, does not create torque or leave residual strain on the tubing, and does not significantly reduce flow area. Interaction of precision parts— body, front ferrule, back ferrule, and nut—produces a leak-free seal with a simple 1 lA -turn pull-up. The Swagelok works on thick or thin wall tubing, and seals consistently over a wide range of pressures, tem- peratures, and temperature cycling. Crawford also offers a complete line of valves and fittings. Shut-off, regulating, check, or relief valves are available in a variety of end connec- tions and ratings to 10,000 psi and 1,200 F. All valves are 100 percent tested. Crawford fittings in fraction- al, metric, and ISO sizes with straight and tapered threads are available in aluminum, brass, car- bon steel, Hastelloy C, Inconel 600, Monel, 316 Stainless steel, titanium, and other machineable metals and plastics. HAYWARD Circle 33 on Reader Service Card The Hayward Marine Division of Hayward Industrial Products, Inc., Elizabeth, N.J., manufactures a broad range of valves, strainers, and fittings for all types of vessels and applications. Hayward's engineered marine products are backed by technical and field assistance worldwide. The company's line of liquid cargo han- dling products includes angle valves, PVR valves, and inverted vent checks, as well as simplex, du- plex, fabricated, and "Y" strainers, and Cu/Ni strainers. JAMESBURY Circle 34 on Reader Service Card Jamesbury Corporation of Wor- cester, Mass., manufactures the Wa- fer-Sphere® high-performance valves that are suitable for 2Vi -inch and larger valve requirements. These valves feature a flexible-lip TFE seat that provides tight shutoff to 1,480 psi in temperatures ranging from cryogenic up to 500 F. They are compact, light, and easy to in- stall, and are said to offer corrosion resistance, long life, and easy, low- cost maintenance. Jamesbury also manufactures a complete line of ball and butterfly valves, valve actuators, and control devices. The company offers a unique Actuator Selection Slide as a (continued)
