A wafer type check valve is a non-return valve that automatically opens with forward flow and closes to prevent backflow, ensuring unidirectional flow in piping systems. This compact and lightweight valve is designed for space-saving installation while providing high efficiency and performance.

Material Options

Carbon steel (WCC, WCB wafer check valve), stainless steel wafer check valve (CF8, CF8M, CF3, CF3M), duplex steel, and alloys such as Hastelloy, Monel, and Inconel.

Size & Pressure Range

Size: 2” to 48” (DN50 to DN1200)
Pressure: Class 150 to Class 1500 (PN10 to PN250)

Key Features

· Automatic Operation: Opens and closes based on fluid flow, reducing the risk of water hammer.
· Compact & Space-Saving: Thin profile for easy installation between flanges.
· Multiple Disc & Seat Options: Metal-to-metal or soft-seated (EPDM, NBR, PTFE, Viton) for various applications.
· Spring-Loaded & Non-Spring Designs: Suitable for both horizontal and vertical installations.
· Low Maintenance: Simple structure with durable materials for extended service life.

Applications

· Water & Wastewater Treatment: Prevents reverse flow in pumping stations.
· Oil & Gas Pipelines: Suitable for high-pressure crude oil, natural gas, and refined products.
· Power Plants: Used in cooling water and steam systems.
· Chemical & Petrochemical Industry: Handles aggressive fluids with corrosion-resistant materials.
· HVAC & Fire Protection Systems: Ensures reliable flow control in chilled water and fire suppression systems.
