Catalog excerpts

This valve is engineered for all liquid or gas applications in the nuclear industry. Typical applications are feed water control systems, dump lines, make-up water, pilot control for large control valves, head vent systems, chemical injection systems, and monitoring/sampling systems. This gate type design uses spring loaded seal discs that seal tightly at all pressures from 0 psig to maximum rating. Extreme reliability is inherent due to the rugged design and simplicity of operation and a minimum number of moving parts. Isolation standoffs prevent excessive heat transfer to the solenoid operator. Because of the straight-through flow path with self-cleaning sealing surfaces, internal passages inherently resist any build-up of contamination and sludge. Compact, lightweight design provides excellent resistance to seismic vibration and shock. A completely enclosed and encapsulated coil ensures continuous operation during LOCA event. • Valve ratings: ANSI class 150 to 2500. • High Cycle life. Over 100,000 operations in most applications. • Resistant to contamination and sludge buildup. • ASME Section III, Classes 1,2 and 3. • Available Fail Safe Closed, Fail Safe Open or Fail in Last Position (Latching). • Position indication switches available for remote status indication. • Solenoid and switch assemblies readily accessible for removal or maintenance without disturbing the pressure boundary. • Stress and seismic analysis available. Qualified to IEEE 323, 344, 382. • Radiation resistance: Standard, 2x10A8 rads. • Qualified Life up to 60 years + LOCA. © 2016 VALCOR ENGINEERING CORPORATION PH: 973-467-8400 FX: 973-467-9592 WWW.VALCOR.COM
