Detail Information
Wafer Piston Check Valve
Piston check valves are automatic valves designed to open with forward flow and close to prevent reverse flow. Their primary function is to safeguard mechanical equipment in a piping system by stopping any backflow of fluid.
Wafer Piston Check Valve-Features
1. Compact and Lightweight: Short length and small volume for easy handling and installation.
2. Durable Sealing Surface: Hard material welded sealing surface is resistant to wear, erosion, and abrasion, ensuring long service life.
3. Low Starting Pressure: Valve discs open fully with minimal pressure difference.
4. Quick Closing: Fast disc closure reduces water hammer pressure.
5. Versatile Installation: Suitable for both horizontal and vertical pipes.
6. Customizable Options: Various materials, sizes, and surface forms are available to match working conditions and customer requirements.
7. Cost-Effective: Economical installation and maintenance due to lightweight design and minimal installation requirements.
8. Water Hammer Prevention: The spring-operated design helps prevent water hammering and accommodates large pipe gaps.
9. Reduced Maintenance: Longer durability and easier maintenance compared to traditional check valves.
