SVR Global is the most reputed Dual plate check valve manufacturer in USA. We supply corrosion free, top-quality valves to chemical industries, marine industries and water industries in New York, Ohio and Alabama. A dual plate check valve is a type of check valve that consists of two plates or discs that are hinged together in the center. The plates are designed to open in response to fluid flow, allowing fluid to pass through the valve, and then close to prevent backflow. This design allows for a more compact valve than traditional swing check valves and provides for a faster response to changes in fluid flow.
These valves operate by utilizing the kinetic energy of the fluid to push the plates open against the force of gravity and any springs or weights that may be used to assist in closure. Under the influence of gravity, as well as springs or weights, the plates of the valve shut when fluid flow ceases or changes direction.
Parts of a Dual Plate Check Valve:
- Body: The main body of the valve, which contains the two plates and the hinge mechanism.
- Plates: two plates hinged together.
- Hinge: A mechanism that connects the two plates and allows them to pivot.
- Spring: A spring mechanism that helps to close the plates and maintain a seal.
- Seals: A set of sealing elements that prevent leakage when the plates are closed.
Types of Dual Plate Check Valves:
- Wafer Type: Wafer type dual plate check valves are designed to be installed between flanges and are held in place by bolts or other fasteners. They are generally less expensive and more compact than other types of check valves.
- Lug Type: Lug type dual plate check valves are similar to wafer type valves, but they have threaded inserts or lugs that allow them to be bolted directly to a pipeline without the need for separate flanges.
- Flanged Type: Flanged type dual plate check valves are designed to be installed between flanges and have a raised face to provide a seal against the flange faces. They are generally more expensive and larger in size than wafer or lug type valves.
