Manual Disc Check Valve

Manual Disc Check Valve is a robust and sturdy fitting which is commonly placed in between the flanges for the prevention of reverse flow of the liquid flowing through the system. It is commonly used in various application areas such as hot water systems, process lines, steam and condensate system. Best in class materials are used for the fabrication of this plumbing units which imparts higher durability to withstand large pressure and temperature. Buyers can get this valve from us in bulk as per their requirements at a reasonable price.

1. Disc Mechanism: The primary feature of a manual disc check valve is its disc mechanism. This disc is typically positioned within the valve body and is free to move along the axis of flow. When the fluid flows in the desired direction, the disc is pushed open, allowing the fluid to pass through. If the flow direction reverses, the disc moves back to its closed position, blocking the flow and preventing backflow.
2. Spring or Weight: Many manual disc check valves are equipped with a spring or a weight to assist in closing the valve when flow direction changes. The spring or weight provides the necessary force to ensure that the disc returns to the closed position effectively.
3. Body Design: The valve body is designed to facilitate the movement of the disc. It includes an inlet and an outlet for fluid to pass through. The interior of the body is shaped to guide the disc's movement, and it often features a seat against which the disc seals when in the closed position.
4. Installation Orientation: Manual disc check valves have specific installation requirements due to their design. They need to be installed in a specific orientation to function properly. Usually, there are arrows or markings on the valve body indicating the direction of flow.
5. Materials: These valves can be constructed from a variety of materials, including metals like stainless steel, cast iron, or bronze, as well as plastics and other specialized materials. The choice of material depends on factors such as the type of fluid being handled, temperature, pressure, and the environment.
6. Sizes and Pressure Ratings: Manual disc check valves come in various sizes to accommodate different flow rates. They are also available with different pressure ratings to suit the requirements of different applications.
7. Manual Operation: As the name suggests, these valves are manually operated. This means that their opening and closing actions are not automatic and require human intervention. This can be advantageous in certain situations where the flow needs to be controlled precisely.
8. Maintenance and Service: Manual disc check valves are relatively simple in design, making them easy to maintain and service. Regular inspection and cleaning are necessary to ensure proper functioning and prevent clogs or other issues.
9. Application Range: These valves are commonly used in applications where backflow prevention is critical, such as in plumbing systems, sewage systems, irrigation systems, and industrial processes.
10. Cost-Effective: Manual disc check valves are generally more cost-effective than their automatic counterparts due to their simpler design and manual operation.
