V526P

Product catalog summary

Description and Features
This document details the V526P solenoid valve designed for liquid or gas applications in the nuclear industry. It is suitable for systems such as feed water control, dump lines, make-up water, pilot control for large valves, head vent systems, and monitoring/sampling systems. Key features include:

Valve ratings from ANSI class 150 to 2500.
High cycle life with over 100,000 operations.
Resistance to contamination and sludge buildup.
Compliance with ASME Section III, Classes 1, 2, and 3.
Fail Safe options: Closed, Open, or Last Position.
Stellite or elastomer seats.
Position indication switches for remote status.
Accessible solenoid and switch assemblies for maintenance.
Stress and seismic analysis qualified to IEEE standards.
Radiation resistance up to 2x10^8 rads and a qualified life of up to 60 years plus LOCA.

Design and Operation
The valve ensures zero leakage to the environment using Valcor’s "through the wall" magnetic operation, eliminating potential leak points. It features a rugged design with minimal moving parts, isolation standoffs to prevent heat transfer, and internal parts designed to prevent contamination buildup. The compact design offers resistance to seismic vibration and shock. The valve uses a pilot poppet to assist the main poppet operation, combining direct lift and pilot design benefits.

Specifications

Solenoid Operator: Class H materials or better, available in various AC and DC voltages.
Electronic Components: Totally enclosed, meeting NEMA 4 standards, and 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.

Valve Types and Operating Conditions
The document lists various valve types (P1AH, P2BH, etc.) with maximum fluid temperatures of 650°F and operating differential pressures (ΔP) in PSI. It also provides typical Cv values, noting that actual values may vary based on applications.

Standards and Qualifications
The valve complies with several standards, including ASME B&PV Section III, B16.34, B31.1, and IEEE standards 323, 344, 382, and ASME QME-1.

Valcor Nuclear - Process Solenoid Valve 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, and monitoring/sampling systems. Absolute zero leakage to the environment. Valcor’s “through the wall” magnetic principle of operation eliminates all potential leak points such as packings, bellows and diaphragms. 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, lightweight design provides excellent resistance to seismic vibration and shock. This design uses a pilot poppet to create a pressure unbalance which assists the operation of the main poppet, thereby combining the best features of the direct lift and pilot designs. • 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. • Stellite or elastomer seats. • 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
