Bronze Dual Plate Check Valve
The Bronze Dual Plate Check Valve is a wafer-type non-return valve designed to prevent reverse flow and reduce water hammer in pipeline systems.
- Product Introduction
Product Overview
The Bronze Dual Plate Check Valve is a wafer-type non-return valve designed to prevent reverse flow and reduce water hammer in pipeline systems.
Its spring-assisted dual-disc mechanism enables fast and stable closure when flow stops or reverses, protecting pumps, pipelines, and downstream equipment from pressure shock and backflow damage.
Manufactured from corrosion-resistant bronze alloy, it is widely used in seawater, marine, desalination, and industrial systems requiring long-term reliability in corrosive environments.

Manufacturing & Quality Control
Each valve is produced under strict industrial quality procedures, including API 598 pressure and leakage testing, material certification verification, dimensional inspection before shipment, and full batch traceability to ensure consistent performance in industrial applications.
Installation Guidelines
The valve must be installed according to the flow direction arrow on the body, is suitable for both horizontal and vertical (upflow only) installation, should avoid direct installation at high-vibration pump outlets, and requires proper flange alignment before tightening.
Delivery & Lead Time
Standard production lead time is 15–30 days depending on size and order quantity, small sizes may be available for faster shipment, OEM or customized orders may require additional 5–10 days, and shipping terms such as FOB, CIF, and EXW are available based on project requirements.
Packaging
Each valve is packed in seaworthy plywood cases or cartons with internal rust protection, clearly labeled with size, pressure rating, and batch number, and suitable for both sea freight and air transportation.
