Product catalog summary
Description and Applications
This document describes the V526G 2-Way Direct Lift Solenoid Valve, designed for liquid or gas applications in the nuclear industry. It is typically used in systems such as feed water control, dump lines, make-up water, pilot control for large valves, head vent systems, chemical injection, and monitoring/sampling systems.

Features
  • Valve ratings range from ANSI class 150 to 2500.
  • High cycle life with over 100,000 operations in most applications.
  • Resistant to contamination and sludge buildup.
  • Complies with ASME Section III, Classes 1, 2, and 3.
  • Available in Fail Safe Closed, Fail Safe Open, or Fail in Last Position (Latching) configurations.
  • Position indication switches for remote status indication.
  • Solenoid and switch assemblies are accessible for maintenance without disturbing the pressure boundary.
  • Stress and seismic analysis available, qualified to IEEE 323, 344, 382.
  • Radiation resistance up to 2x10^8 rads.
  • Qualified life up to 60 years plus LOCA (Loss of Coolant Accident).

Design and Reliability
The valve features a gate-type design with spring-loaded seal discs for tight sealing at all pressures. It is designed for extreme reliability with minimal moving parts and a straight-through flow path that resists contamination and sludge buildup. The compact and lightweight design offers excellent resistance to seismic vibration and shock. The coil is fully enclosed and encapsulated to ensure continuous operation during a LOCA event.

Specifications
  • Solenoid Operator: Class H materials or better, available in various AC and DC voltages.
  • Electronic Components: Totally enclosed, meeting NEMA 4 standards or better, qualified to IEEE 323.
  • Line Connection: Standard socket weld, with optional butt weld or tube extensions.
  • Body Material: Standard stainless steel, with optional carbon steel.

Performance
The valve can operate at a maximum fluid temperature of 650°F with varying operating differential pressures depending on the valve type. The document provides typical Cv values for different valve types.

Standards and Qualifications
  • Valve complies with ASME B&PV, Section III Class 1, 2, & 3, B16.34, B31.1.
  • Qualified to IEEE 323 (1974, 1983, and later editions), IEEE 344 (1975, 1987, and later editions), IEEE 382 (1980, 1996, and later editions), and ASME QME-1 (2007 and later editions).

Catalog excerpts

V526G-1

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
