Specialty Valve is a leading Swing Check valve manufacturers in India . A swing check valve is a type of check valve used in piping systems to allow flow in one direction while preventing backflow in the opposite direction. It typically consists of a hinged disc, known as the swing disc or flap, inside the valve body.
How does it work?
The main structure of the valve, usually made of metal or plastic, contains the internal components. The swing check valve's distinguishing feature is the swinging disc or flap, which is hinged at the top of the valve body. When there is forward flow (flow in the desired direction), the pressure of the fluid pushes the disc open, allowing the fluid to pass through the valve. In some designs, a return spring is used to help close the disc when flow stops.
This ensures that the disc closes promptly, minimizing the risk of water hammer or reverse flow. The seat is the sealing surface against which the swing disc closes to prevent backflow. It ensures a tight seal when the valve is closed, preventing any fluid from flowing backward through the system. The hinge pin is the pivot point for the swing disc. It allows the disc to swing open and closed as fluid flows through the valve. When flow stops or reverses, the swing disc swings back to its closed position under the influence of gravity or a return spring. This effectively seals off the valve, preventing any backflow.
Swing check valves offer several features that make them suitable for various applications.
Here are some key features:
Some swing check valves may include additional features such as external lever and weight for adjustable closing speed, bolted bonnet for easy maintenance, or rubber-coated disc for improved sealing. Compliance with Standards: Swing check valves are often designed and manufactured to meet industry standards and specifications, ensuring performance and reliability in various applications.
Installation :
When installing swing check valves, prioritize horizontal orientation to prevent water hammer and ensure effective operation. Vertical installations, particularly with upward flow, risk the disc slamming against the seat when flow stops.
Confirm flow direction matches valve indications. Mount securely with ample clearance for maintenance. Use appropriate methods for threaded, flanged, or welded connections. Conduct pressure tests post-installation and clearly label for easy identification during maintenance.
