Features:

- Tilting Disc Design: A key element is a disc positioned at an angle (usually 15-25 degrees) relative to the flow path. This angle allows for smooth opening and closing with minimal pressure drop.
- Spring-Assisted Closure (Optional): Some designs incorporate a spring to aid disc closure, guaranteeing positive shutoff even at low flow rates.
- Low-Noise Operation: The tilting disc design minimizes slamming and noise compared to swing check valves, making them suitable for quiet operation environments.
- Bidirectional Flow (Optional): Certain tilting disc check valves can handle flow in either direction, offering operational flexibility.
- Material Variety: Available in various materials to suit different pressure ratings, temperatures, and fluid compatibility requirements.
- Short body, small volume and light weight
- Shafts protrude on both sides of the body and allow the lever and counter weight to be mounted on the right or left side, both vertical and horizontal pipeline applications.
- Disc swings freely. The disc opening depends on the flow velocity
- Adjustable weight offers the adaptability to the individual working conditions.
- Metal to metal or resilient seating options.
- Maintenance free design.
- Tilting Disc Check Valves With Hydraulic Damper eliminate the closing slams and water hammer for entire closing stroke.
- Closing speed is adjustable depends on working conditions.
- All components of the valves are designed for high stress occurred during damping effect.

Benefits:

- Low Head Loss: The tilted disc design minimizes flow restriction, resulting in lower pressure drops and improved efficiency within the piping system.
- Reliable Shutoff: The design ensures positive sealing, preventing backflow even at low pressures (with spring-assisted closure).
- Reduced Water Hammer: The tilting disc promotes smoother flow transition, minimizing the risk of water hammer (pressure surges) that can damage pipes and equipment.
- Quiet Operation: The design minimizes slamming and noise, making them ideal for applications requiring quiet operation.
- Versatility: Available in various materials, sizes, and configurations (bidirectional flow) to suit a wide range of applications.

FAQs:

A. What differentiates a tilting disc check valve from a swing check valve?

- Tilting Disc: Disc sits at an angle, offering lower head loss and quieter operation.
- Swing Check: Disc swings on a hinge, can experience higher head loss and slamming.

B. What are the advantages of a spring-assisted closure?
