Dual Plate Check Valve Manufacturer in USA
SVR Global is the most reputed Dual plate check valve manufacturer in USA. We provide top-quality, corrosion-free valves to the chemical, marine, and water sectors in New York, Ohio, and Alabama. A check valve with two plates or discs that are hinged together in the middle is known as a dual plate check valve. The valve’s plates are made to respond to fluid flow by opening to let fluid pass through, then closing to stop backflow. Compared to conventional swing check valves, this design enables a smaller valve and offers a quicker response to changes in fluid flow.
These valves work by using the fluid’s kinetic energy to drive the plates open in opposition to gravity and any springs or weights that might be utilized to help.
Parts:
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:
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.
