The HC42X Silent Check Valve is a valve used in pipeline systems to prevent backflow of media, automatically controlling the opening and closing of the valve disc through media flow, featuring silent operation, anti-backflow, and anti-water hammer capabilities.

Core Features

Anti-Backflow: Automatically closes the valve disc using the pressure difference of the medium to prevent backflow of the pipeline medium.

‌Silent Design: Reduces water hammer noise during rapid valve disc closure, meets environmental protection standards.‌

Streamlined channel: Low pressure loss, suitable for water supply, drainage, and fire protection systems.

Structural Features

Material: Valve bodies, valve seats, and other components are made of ductile iron, stainless steel, and other materials, offering wear and corrosion resistance.

‌Installation Methods: Supports both horizontal and vertical installation, adaptable to various pipeline structures.‌

Performance Parameters

Nominal Pipe Size: DN50~DN500mm.

Nominal Pressure: PN1.0MPa, PN1.5MPa, PN2.5MPa.

‌Working Pressure: 1.0 MPa (PN 1.0 MPa), 1.6 MPa (PN 1.5 MPa), 2.5 MPa (PN 2.5 MPa).‌

Installation Precautions

Ensure the medium flow direction is consistent with the arrow on the valve body.

Large valves require independent supports to prevent bearing the weight of the pipeline.
