The 1.4308 PN16 Dual Plate Check Valve is a wafer butterfly one-way valve designed for industrial fluid control applications. This compact valve features a dual-plate design with spring-assisted closure for reliable backflow prevention.

• Design: AP1594, API6D, JB/T8937
• Face to Face: API594, API6D, DIN3202, JB/T8937
• Pressure & Temperature Rating: ASME B16.34
• Test & Inspection: ANSI B16.50, DIN2401, GB/T9124, JB/T74

This dual plate wafer check valve employs two spring-loaded plates hinged on a central hinge pin. The internal assembly consists of two semicircular springs and plate surfaces fixed to the valve body by pins. Spring deformation enables rapid valve closure while fluid pressure opens the plates, providing fast response that protects pipelines from water hammer damage.

• Compact wafer-style one-piece design for space efficiency
• Center post fully supports internal assembly without external pins or plugs
• Maximum flow area minimizes pressure loss
• Dual-plate design provides increased strength with reduced opening and closing time
• Torsion springs assist valve plate closure to prevent flow reversal
• Consistent valve response prevents slamming and water hammer
• Heavy-duty corrosion-resistant shaft construction
• Corrosion-resistant shaft supports act as stops to prevent over-travel
• Thrust washers reduce friction and wear on valve plate hinges

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.
