Description

The wafer check valve is a specially designed check valve. It is usually installed between pipe flanges and fixed by bolts. The main application scenarios are water supply system, HVAC system, petrochemical, sewage treatment.

    Product Details

    A Single Plate Check Valve is a compact, wafer-type non-return valve designed to prevent reverse flow in piping systems. It features a single swing disc that opens automatically under forward flow and closes quickly when the flow stops or reverses, ensuring reliable backflow prevention and system protection.

    Working Principle

    When the fluid flows in the correct direction, the pressure pushes the disc open, allowing smooth passage through the valve. Once the flow stops or reverses, the disc automatically swings back to the seat, closing the valve and preventing reverse flow without the need for external control.

    Key Features

    Compact Wafer Design
    Single Swing Disc Structure
    Automatic Backflow Prevention
    Low Pressure Drop
    Flexible Installation
