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.
