An Introduction to Dual Plate Check Valves: Definition, Types, Features and More
Июл . 17, 2024
Dual plate check valves are mechanical valves that prevent backflow and ensure fluid flow in one direction. For anyone interested in learning more about this significant piece of engineering technology, this article provides a comprehensive overview of its design, principles, and applications.Dual plate check valves, also known as check valves with two plates and two plugs. They are used in major HVAC/R systems, water supply lines, oil/natural gas pipelines, steam and condensate systems to regulate liquid, gas, steam, and steam volumes.

Dual Plate vs. Swing Check Valve
Июл . 17, 2024
Check valves are automatic valves that open with forward flow and close against reverse flow. The main function of a check valve is to protect mechanical equipment in a piping system by preventing fluid reversal. A swing check valve is an economic type of check valve, but it has a high slamming effect. Dual plate check valves are more popular than swing check valves in Norwegian offshore industry [16] because they have a low slamming effect. Additionally, the total cost of a dual plate check valve—initial cost, maintenance cost, and energy cost—is less than a swing check valve. In fact, swing check valve makes more pressure drop and energy consumption in pumping system. However, the minimum flow capacity may not produce enough pressure during the usage of dual plate check valves, which results in two operational problems. The valve loses more pressure when it is not in a fully open position, and in addition to a rise in energy consumption, insufficient flow velocity can wear the valve. A case study of minimum flow capacity and velocity calculation for fully opening a 22Cr duplex dual plate check valve in ASME pressure class 300 is discussed in this paper. The minimum flow in the example is lower than minimum critical flow required to fully open the valve. Thus, to avoid operational problems, it is recommended to not operate the valve with minimum flow. The other recommendation is to avoid installing the valve on the vertical line. Reducing the size of the valve and spring torque behind the disk are two other solutions to mitigate operational risks due to a minimum flow condition.

Dual Plate Check Valve
Июл . 17, 2024
The dual plate check valve or dual disc check valve is known as non-return valve or retainerless check valve. The valve allows the medium to flow in one direction only and to prevent flow of fluids to the opposite direction. The valve is working in an automatic system which contains an articulated mechanism. It is much lighter in weight and smaller in size compared to a conventional swing check valve body design. This valve design is the result of attempts to provide an alternative in solving the problem associated with swing check valves. The valve contains two spring-loaded plates that are hinged on a central hinge pin.
