Tilting Disc Check Valve

Overview

Tilting disc check valves, also known as slanted disc check valves, are widely used due to their efficient operation, minimal maintenance needs, and versatility.

Key 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.

Applications

• Water Supply
• Water Treatment
• Irrigation

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.
