Single Disc Wafer Check Valve

Product Overview

The Single Disc Wafer Check Valve is a compact, non-return valve designed to prevent backflow in pipeline systems. Installed between flanges in a wafer-style configuration, it allows fluid to flow in one direction only and automatically closes when flow reverses, protecting pumps and equipment from damage.

Key Features

• Wafer-type compact design for easy installation

• Single disc (swing or spring-loaded) structure

• Automatic non-return function (no external control required)

• Fast closing response to prevent backflow

• Low pressure loss and smooth flow passage

• Lightweight and space-saving construction

• Available in various material options for different media

• Suitable for horizontal and vertical installation (model dependent)

Applications

• Water supply and drainage systems

• HVAC and cooling water systems

• Pump protection systems

• Industrial pipelines

• Chemical and process industries

• Oil and gas auxiliary systems

• Fire protection systems

• Irrigation and agricultural systems
