Single Disc Wafer Check Valve

Wafer check valve structure and application

Wafer check valve has the advantages of simple structure, beautiful appearance, light weight and convenient installation. It is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors, and it is more suitable for places with limited installation space.

Features & Benefits

Single-Disc Wafer Check Valves are designed for installation in flanged piping systems in both horizontal and vertical orientations. Compatible with applications such as gaseous compressors and blowers, water and oil pumps, and biofuels production.

Low weight design, 80% – 90% weight reduction compared to full body swing check valves

Versatile functionality for horizontal and vertical installations

Integrated single piece cast disc and arm assembly increases unit integrity

Simplifies piping, optimizes space utilization, and lowers installation costs

Simple in-field repairability to mitigate downtime

Traditional and zero fugitive emission designs available
