Check valves serve as essential one-way or non-return valves in virtually all industrial applications. These simple yet vital devices prevent reverse flow, protecting equipment from damage and ensuring operational efficiency. Reverse flow can cause water hammer—a phenomenon involving repeated extreme pressure surges that can fatally damage or rupture connected pipework, valves, and pumps. Even without immediate failure, repeated water hammer impacts can promote fatigue, ultimately compromising system integrity.

Our dual plate check valves offer cost-effective solutions with low head loss characteristics when fully open. Unlike traditional swing check valves that may slam in vertical installations due to long disc stroke and inertia, our design incorporates two torsion springs that exert force on each valve plate, ensuring quick and automatic closure.

• Compact design with small size, light weight, and easy maintenance
• Dual torsion spring mechanism for rapid automatic closure
• Quick-close action prevents medium backflow and eliminates water-hammer effect
• Short length design provides rigidity and easy mounting
• Suitable for both horizontal and vertical pipeline installations
• Leak-proof performance verified through pressure water testing
• Safe, reliable operation with high interference resistance

Packing: We utilize appropriate plywood cases tailored to different valve types, with skilled workers ensuring protection against bruising during transit.

Delivery: 7-40 days based on order quantity after deposit confirmation. We partner with long-term forwarders for efficient space booking, customs clearance, and transportation via sea, air, or rail according to customer requirements.
