Key Features & Benefits
- Compact wafer-style one-piece design for space-efficient installation
- Center post fully supports internal assembly without external pins or plugs
- Maximum flow area reduces pressure loss and improves efficiency
- Dual-plate design provides increased strength with reduced opening and closing time
- Torsion springs assist valve plate closure, preventing flow reversal and water hammer
- Heavy-duty corrosion-resistant shaft construction for extended service life
- Shaft supports act as stops to prevent over-travel of valve plates
- Thrust washers reduce friction and wear of valve plate hinges
Application Details
The dual plate wafer check valve employs two spring-loaded plates hinged on a central hinge pin. The internal mechanism consists of two semicircular springs and plate surfaces fixed on the valve body by a pin. Spring deformation enables rapid valve closure, while fluid pressure opens the valve. This fast response time protects piping systems from water hammer damage in industrial fluid control applications.
Packaging & Delivery
Valves are packed in suitable wood cases by skilled workers to prevent damage during transit. We work with long-term forwarders for space booking, customs clearance, and transportation via sea, air, or rail according to customer requirements. Delivery time ranges from 7 to 60 days based on order specifications.
