Swing Disc Check Valve

Product Overview

The Swing Disc Check Valve is a non-return valve designed to prevent backflow in pipeline systems. It operates using a hinged disc that swings open with forward flow and automatically closes when flow reverses, ensuring system safety and protecting pumps and equipment from damage.

Key Features

• Swing-type disc design for smooth flow control

• Automatic non-return operation (no external power required)

• Low pressure drop during forward flow

• Strong sealing performance to prevent backflow

• Robust construction suitable for industrial use

• Available in various materials and pressure ratings

• Suitable for horizontal installation (typical design)

• Long service life with minimal maintenance

Applications

• Water supply and distribution systems

• HVAC and cooling water systems
