Valve Equipment Guide user aid in matching actuator to valve. With this chart, the user selects the type of Jamesbury valve (threaded end ball, flanged ball, or high-performance butterfly), sets the Valve Torque Guide to the max- imum differential pressure of the planned application, and matches this to a jamesbury actuator best suited for the application. KEYSTONE Circle 35 on Reader Service Card The K-LOK extended service butterfly valves manufactured by Keystone Valve USA of Houston, a division of Keystone International, Inc., are included on the Qualified Products List per Military Specifi- cation MIL-V-24624(SH), Amend- ment 1, Types I, II, III, and IV. The K-LOK is rated to 285 psi and is fire-tested in accordance with API- 607. Both wafer and lug style K-LOK valves have met or exceeded all test requirements in sizes 14 inches and under. The K-LOK has been approved for a variety of marine applications, including JP-5 fuel-handling sys- tems, as well as for diesel oil and lubricating oil handling systems. K-LOKs are also being used in salt- water handling systems such as fire mains and in cooling water and chilled freshwater systems. LIMITORQUE Circle 36 on Reader Service Card Limitorque Corporation of Lynchburg, Va., has just introduced a comprehensive line of pneumatic valve actuators, the HR Series, that meets virtually any service condi- tion required. Ranging in torque outputs from 70 to 250,000 inch- pounds, on supply pressures varying from 40 to 120 psi, the new line fea- tures a slim profile design for easy installation and maintenance, and an all-cast-iron construction to meet harsh environmental requirements. Standard features include built-in adjustable stroke stops with adjust- ments ranging from 80 to 100 degree travel, and double scotch yoke mechanisms for improved balance. Limitorque also offers the T Se- ries worm gear operator for manual and motorized control of any valve or mechanism requiring 90-degree rotation. These new operators are available in two series: a commercial series for general industry applica- tions, utilizing ductile iron worm gears; and an AWWA series meeting A WW A C504-80 specifications and incorporating bronze worm gears. All components in both series fea- ture rugged, high-strength cast iron enclosures, self-locking worm gears with minimum gear backlash, full O-ring sealed construction, and ex- ternal mechanical stops to provide plus or minus travel adjustability. MUELLER Circle 37 on Reader Service Card A complete line of butterfly valves, check valves, and needle valves is manufactured by Mueller Steam Specialty of Lumberton, N.C., and distributed through Ma- rine Piping Products of New Hyde Park, N.Y. All types of body trim material are offered in a wide range of sizes, pressure ratings, and end connec- tions. Each valve is hydrostatically tested before shipment. Test re- ports and physical certifications on all products are available from Mueller. NEWMAN'S Circle 38 on Reader Service Card Newman's Inc., headquartered in Tulsa, Okla., markets a full line of marine valves under the brand name NEWCO. They are available in stock in a size range from 2 to 24 inches, in classes 150# through 2,500#. They come in gate, globe, angle, and check types. These marine valves are bronze trimmed with stainless steel, Stel- lite, Monel, and other special trims upon specification. They are used in saltwater applications such as tank- ers and cargo ships, barges, dry- docks, and pipelines. All meet MSS, ASTM, and ASME specifications, and are American Bureau of Ship- ping inspected. NEWCO marine valves are stocked in depth at local distribu- tors to facilitate customer accessi- bility. They may also be ordered directly from the manufacturer's seven strategically located ware- houses in Tulsa; Houston; East Brunswick, N.J.; Milwaukie, Ore., Chicago; and in Edmonton and Bar- rie, Canada. NORRIS Circle 39 on Reader Service Card The O-ring butterfly valves man- ufactured by Norris Flow Products, a division of Dover Resources, Inc., Tulsa, Okla., are backed by 25 years of experience serving the marine industry. The valves are offered in sizes 2 through 36 inches, and in various types such as wafer span, double rib, full lug, and long neck. The elastomer-lines R-Series has a temperature range of —35 to + 250 F, depending on seat and seal material and media handled. The valve body is isolated from the flow stream by a resilient elastomer seat and O-ring seals. Angle-disc con- struction gives 360-degree uninter- rupted contact of disc with seat. This series meets various commer- cial and military specifications for shipboard use as ballast, cargo-han- dling, cooling water, and machinery valves. The metal-lined M-Series has a temperature range of —40 to +550 F, depending on seal material and media handled. It features field- replaceable metal seat and shaft O- ring seals that isolate the valve body from the flow stream, thereby elimi- nating the need for premium body material. This series is said to be ideally suited for more severe appli- cations that ordinarily cause swell- ing of the elastomer. Norris also manufactures ANSI 150 valves rated 285 psi, designed for positive shutoff in severe service. These also come in elastomer-lined and metal-lined series, in sizes 2 through 36 inches. The company also offers air cylinder assemblies for operating its valves in 2- to 24- inch sizes. PITTSBURGH BRASS Circle 40 on Reader Service Card Pittsburgh Brass Manufacturing Company (PBM) of Irwin, Pa., has extended its product line by offering a complete range of actuated ball valves the company calls "Perform- ance Packages." Highly efficient, power-driven actuators are mated to PBM's Adjust-O-Seal ball valves in all styles, all metals, and all sizes. Depending upon specific require- ments, actuators may be either elec- tric or pneumatic, and if pneumatic may be of vane or piston type, and if electric may be reversible type. A full complement of accessories is available, including solenoid valves, limit switch boxes, regulator systems, positioner systems, motor brakes, auxiliary switches, heaters, and thermostats. PBM markets a complete range of two-way bronze valves in a choice of alloys with any type trim, including Monel. These valves feature sil- braze ends, Navy flanges, detenting handles, and blowout-proof stems. Manufactured to U.S. Navy and Coast Guard specifications, the PBM line of ball valves has been shock and vibration tested. These valves are available in Vi - to 4-inch sizes, pressures to 700 psig, and tem- peratures to 450 F. (continued)
