Product Description

Casting Forging Flange wafer type single-disc double-disc swing spring check valve:

Wafer-Type Single and Double-Disc Check Valves:
These valves are vital components in fluid systems, ensuring one-way flow while preventing backflow.
 

Single-Disc Check Valve:

Design: Compact and lightweight, it features a single disc pivoting on a hinge, allowing fluid flow in one direction.

Versatility: Ideal for space-limited installations, widely used across industries for reliable backflow prevention.

Double-Disc Check Valve:

Design: With two discs for synchronized operation, it minimizes slamming for smoother, wear-resistant performance.

Applications: Commonly applied where quick, reliable shut-off is critical, such as in water treatment and chemical processing.

Both these wafer-type check valves excel in space efficiency and reliability, serving diverse industries to ensure fluid handling systems operate seamlessly.
