M type expanding gate valve has a non-rising stem with a expanding gate design to provide safe dependable services in a variety of environments. It is available in flanged ends or threaded ends in standard bore sizes from 1-13/16" through 7-1/16" in working pressures from 2,000 psi to 10,000 psi.
Ball Screw Operator is available for large bore and high pressure gate valves. All of our valves can be actuated by hydraulic or pneumatic actruators.
FALLS CHURCH, Va., April 14, 2011 /PRNewswire/ -- Curtiss-Wright Flow Control Company announced today that it will be expanding its commercial nuclear power teaming agreement with its partner Cameron International Corporation to include support for its WKM? Pow-R-Seal? gate valves.
Under the agreement Curtiss-Wright will manufacture the adapter spool Pow-R-Seal expanding double disc gate valves under its Quality Assurance (QA) program in accordance with ASME Section III, Division 1 and NQA-1 Quality Standards for Class 1, 2 and 3 requirements for nuclear power plant applications. Work on this contract will be performed by Curtiss-Wright Flow Control Company's Enertech business unit in Brea, California. "We are very pleased with this expanded teaming agreement," said David Linton, President, Curtiss-Wright Flow Control and Co-Chief Operating Officer of Curtiss-Wright Corporation.
"Enertech and Cameron have worked in close cooperation on the design and manufacture of the NozzleCheck reverse flow protection valve. The addition of the Pow-R-Seal gate valve to this product offering provides plant designers and owners with solutions for both general and high-energy system isolation needs."
Cameron's WKM Pow-R-Seal gate valve operates in nuclear service in support of the demanding Main Steam and Feedwater isolation applications. It has proven to have a lowcost of ownership for containment boundary use when compared to other valve types. The Pow-R-Seal's design also provides low pressure drop for compatibility with today's large turbines used in EPU (Extended Power Uprate) and new construction applications.
Enertech will control the Pow-R-Seal with its IEEE qualified (382, 344, 323), ElectroHydraulic Operator (EHO), pneumatic, or electric motor actuator. Global Demand for advanced main steam and feedwater isolation valves is estimated at over 2,000 units over the next decade.
