Product Description

Check Valves

Check valves are essential components in fluid systems, designed to prevent reverse flow and protect equipment from potential damage caused by backpressure or contamination. Spirax Sarco offers a wide range of check valves suitable for various applications and industries.

Disc Check Valve (DCV)

Features: Compact, fits between pipeline flanges, spring mechanism for reverse flow prevention.

Applications: Steam, condensate lines, process lines, hot/cold water systems.

Heavy-Duty Disc Check Valve (DCV10)

Features: Designed for high-flow conditions, centrally guided for reliability.

Applications: Pump systems, high-pressure fluid systems.

Split Disc Check Valve (SDCV)

Features: Compact, handles larger sizes, split disc design.

Applications: Large-scale steam/process lines, systems requiring minimal pressure drop.

Swing-Type Wafer Check Valve (WCV)

Features: Lightweight, unobstructed flow path, disc swings open with flow pressure.

Applications: Pipelines with sludge/pulp, large diameter pipelines.

Lift Check Valve (LCV)

Features: Robust, virtually maintenance-free, replaceable seats.

Applications: Steam boilers, general fluid systems.

Sanitary Check Valve (CVS10)

Features: ASME BPE compliant, suitable for pharmaceuticals, metal or soft seats, FDA/USP compliant materials.

Applications: High purity fluid systems, pharmaceutical manufacturing.

Benefits of Check Valves

Protect Equipment: Prevents damage from reverse flow.

Reduce Contamination Risk: Minimizes cross-contamination.

Improve Quality: Ensures accurate flow measurement.

Compact Design: Space-saving without compromising performance.
