Nuclear Products Sales Representatives Request Information What's New	6" Solenoid Valve Represents the Latest Advancement of Valcor’s Technology for the Nuclear Power Plant (NPP) Market. Four (4) valves are destined for use in South Korea’s latest NPP construction project, Yonggwang Units 5&6. The design, to ASME III Code requirements, "N"-Stamped, is one of the largest to be developed by Valcor. The prototype unit is being subjected to an extensive set of design qualification tests to ensure that it can perform its intended safety function even after being in service for 40 years. Amongst other tests, the unit is exposed to thermal and radiation aging, vigorous shaker table testing to confirm that it will operate during an earthquake, and flow interruption tests at 1050 GPM. In addition to its size, the process used to conceive and fabricate the design was a new and innovative approach for Valcor Nuclear. Because of our limited ability to physically handle equipment of this size, Valcor has partnered with another ASME fabricator of large control valves, FlowServe (Williamsport, PA), to jointly design and build the unit. Valcor assumed the primary and overall design responsibility to ensure the electrical operator and valve internals meet with the Customer’s performance requirements, with FlowServe being assigned the responsibility to design and build the pressure boundary parts (body, bonnet, disc) in accordance with the ASME Code. FlowServe will also be carrying out all the factory tests on the assembled units and participate extensively in the IEEE qualification. The valves will ultimately bear the name of both companies. Valcor to Manufacture and Sell the Hoke^Ž Line of Nuclear Valves Valcor Engineering Corporation^Ž and Hoke, Inc., have agreed that Valcor will assume responsibility for the provision of ASME III and Safety Related Hoke Valves to the worldwide nuclear industry. Valcor will manufacture and provide a series of Hoke Valves which have been specially designed for use in nuclear service, and will also provide nuclear versions of certain of Hoke's commercial product lines. Hoke has an extremely large installed base and is well known for their instrumentation, needle, globe and bellows valves, as well as for manifolds, sampling bottles, and Gyrolok^Žfittings. Hoke's N2811, N4214 and N9303 series are the most predominant "N" stamped valves in use in the nuclear industry, but Valcor is able to supply any Hoke valve previously "N" stamped or used in nuclear service.

Valcor and Fox Valve Cooperate for Design and Manufacture of Cavitating Venturis Valcor Nuclear and Fox Valve Development Corporation have concluded an agreement which allows Valcor to provide Cavitating Venturis of Fox design to the nuclear power industry. These venturis are designed and manufactured in accordance with the ASME Boiler and Pressure Vessel Code, Section III, and can be "N" stamped by Valcor in accordance with its ASME Certification. Fox Valve Development Corporation was founded in 1961 based upon venturi technology, and has grown into a major supplier of venturi devices to various markets, including power, industrial, and aircraft and aerospace. Fox has developed cavitating venturi designs since its inception and is generally recognized for its expertise in that field. Fox is located in Dover, New Jersey. Valcor will act as the primary supplier, and will take responsibility for the detailed engineering, manufacture, and test of the devices. Valcor will provide the performance guarantees and hardware warranty. The supply will be undertaken in cooperation with Fox, who will provide to Valcor the conceptual design of the venturis as well as such technical assistance as may be required during the course of the contract. Cavitating Venturis are passive flow control devices (no moving parts) which, when installed in a piping system, limit the flow of fluid to pre-determined levels. The convergent-divergent shape of the venturi has a reduced throat area which induces flashing and re-condensation of the fluid (referred to as cavitation) in such a manner as to limit the flow rate. They can be used to assure an equal distribution of fluid in a multiple-branch system, and are commonly used in the emergency feed systems of nuclear power plants for this purpose.

Valcor Successfully Tests New SSPV Valve Valcor has developed and functionally tested a totally new air pilot valve intended for use as a Scram Solenoid Pilot Valve on GE Boiling Water Reactors. SSPV's in service have been a constant performance headache for utilities for several years, and a number of operating plants have been moving towards replacement with a different type of valves. The Valcor design meets the narrow specifications which apply to this critical service valve, which is used to signal the insertion of the reactor control rods during a reactor scram. It is an AC-powered, pilot operated 3-way air pilot valve, which does not use diaphragms (diaphragms have been the cause of slow response times for existing valves). The valve is available in two models, V70900-116, a two-solenoid "T-Type" arrangement, and V70900-116-1, a single solenoid "dual" arrangement. For this valve, Valcor departed from its normal DC solenoid technology and designed a brand new AC solenoid. The AC supply, combined with the exceptionally fast response time required of the valve, precluded the use of a rectified DC coil for this particular application. Valcor Joins with BW/IP Anchor Darling to Extend Product Line Size Valcor and BW/IP Anchor Darling have joined together to manufacture larger bodied solenoid operated valves. the team has been successful in winning a recent order form Hanjung, and expects to bid on several other projects over the balance of the year. Valcor is Now Your Source for Circle Seal Nuclear Valves Valcor, under license from Circle Seal Controls, Inc., Corona, CA is now supplying "N" stamped and Safety Related Circle Seal check, excess flow, and solenoid valves to the nuclear industry. We also support spare parts for these models. Contact Ravi Mahadevan at ext. 234.
