Maritime Reporter, October 1993

<BODY> <div> Coast Guard Approves Marine P-V Valve Electromechanical Research Laboratories, Inc. (E.R.L.) received U.S. Coast Guard (USCG) approval for a new marine pressure-vacuum relief valve. Constructed of stain- less steel, the valve was tested in accordance with A.P.I. 2000, the USCG reports, and approved for use in vapor control systems. The valve, marketed under the name Superac, is an eight-inch, high- velocity model which employs an operating mechanism located out- side of the exhaust air stream, to eliminate valve sticking and improve reliability. Stainless steel bearings are used at all pivot points, which greatly improves the accuracy of the valve, the company reports. E.R.L. tests show the valve is repeatable to within three percent of the set point, and has a total pressure increase of less than five percent from initial opening to the full-open flow rate. Other characteristics of the Superac are its quiet operation, sim- plicity of design, high velocity dis- charge and manual test levers. Also, the valve can be inspected without tools, the company said.
