Mark Controls Expands

SD Butterfly Control Valve Line —Free Literature Available

Mark Controls Corporation's Center Line Se- ries SD butterfly control valve line has been expanded to include the SDT, a heavy duty, 300-psi rated valve. The SDT, as well as the other series SD butterfly control valves, have been designed for low-flow-rate-control applica- tions involving gaseous, liquid or slurry flow media, where tight shutoff is not required. Shut- off leakage capabilities for these valves range from 0.5 percent to 2 percent of the maximum capacity for liquid flow depending on specific materials of construction and temperature pa- rameters.

Series SD butterfly valves are available in standard temperature options of 500°, 850° and 1,200° F, as well as optional configurations for applications up to 1,600°F. All SD Series valves except the SDL and SDM are designed with an outboard combination radial/thrust bearing, which provides easy shaft rotation and allows the valve to be installed with the shaft in either the vertical or horizontal position.

Center Line Series SD valves are wafer style butterfly valves available in sizes ranging from 2 to 36 inches. Standard construction materials are a cast iron body, ductile iron disc and corro- sion-resistant steel shaft. The valves are also available in many other material configurations to satisfy the operating parameters of almost any application.

The Fourth International Maritime Exposi- tion will be held at the New York Hilton Hotel in New York City on November 13-15, 1985, in conjunction with the 93rd Annual Meeting of

The Society of Naval Architects and Marine

Engineers.

Industry professionals from around the world and in every phase of maritime life are expected to participate in these meetings. At the 1984

Exposition, 25,000 square feet of floor space was rented to companies that exhibited to 3,251 attendees.

Companies wishing to exhibit during the 1985

Exhibition should get in contact with the man- agement firm, Reber Friel Company, King of

Prussia, Pa. 19306, phone (215) 265-0825.

Shipbuilding Standards Groups

Seeking Participants

ASTM Committee F-25 on Shipbuilding, and

The Society of Naval Architects and Marine

Engineers (SNAME) Panel SP-6 on Marine

Industry Standards, are seeking participants to join in their standards development activities.

The two groups are working cooperatively to implement marine industry standards that will result in reduced costs and reduced design, con- struction, and repair time for marine vessels.

At a recent meeting of F-25 and the SNAME

Panel, the objectives of the Department of

Defense Value Engineering Committee were dis- cussed. The DoD is investigating ways to reduce costs and improve quality by adopting ASTM industry standards, wherever possible, in lieu of

Navy Military Specifications.

Individuals and organizations interested in the work of Committee F-25 should contact

ASTM staff manager Katharine Schaaf,

ASTM Standards Development Division, 1916

Race Street, Philadelphia, Pa. 19103, (215) 299- 5529. Those interested in SNAME Panel SP-6 should contact Thomas O'Toole, Bath Iron

Works Corporation, Department 56, 700 Wash- ington Street, Bath, Maine 04530, (207) 443- 3311, ext. 2943.
