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.

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 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.

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.
