The SV520-50 Series Excess Flow Check Valves from Valcor Engineering Corporation are specifically designed for liquid applications in the nuclear power industry, prioritizing personnel safety. These valves feature a solenoid-operated reset capability, allowing for remote operation after downstream system restoration. The construction is fully welded, ensuring zero leakage to the environment, and the design minimizes the number of moving parts, enhancing reliability. These valves are capable of sensing and shutting off fluid flow surges caused by downstream line ruptures, with position switches providing remote indication of valve status. They are rated for ANSI classes 150 to 2500 and can handle operating pressures up to 2500 PSIG and temperatures up to 650¬8F. The line sizes range from 3/8,Äù to 2,Äù, and the valves are resistant to contamination and sludge buildup. The body is typically made of stainless steel, with options for Stellite or elastomer seats. The solenoid operator is constructed from Class H material or better, compatible with 120 VAC or 125 VDC, with other voltage options available.
Extreme reliability is inherent due to rugged design, simplicity of operation, and a minimum number of moving parts. Isolation standoffs prevent excessive heat transfer to the solenoid operator. Internal parts are contoured to retard buildup of contamination and sludge. Compact, light weight design provides excellent resistance to seismic vibration and shock. A completely enclosed and encapsulated coil ensures continuous operation during a LOCA event.
These check valves are engineered for liquid or gas applications in the Nuclear industry. Typical applications are feed water control systems, dump lines, make-up water, miscellaneous process systems, N2 systems,monitoring and sampling systems.
