A check valve with two hinges is called double plate control valve. The fluid flow direction causes these plates to open and close. The fluid can pass through when the plates open in the direction of forward flow. The plates automatically close when the fluid reverses, avoiding backflow and harm to the system.
Why Use Dual Plate Check Valves?
Dual plate check valves are often used due to their efficiency and reliability. Here is why they are preferred for most applications:
- Backflow Prevention: The primary purpose of a dual plate check valve is to prevent reverse flow in the system, which could lead to damage, contamination, or operational failure.
- Compact and Lightweight Design Dual plate check valves have a more compact and lightweight design than the traditional swing check valves. It makes it more ideal for installations in limited spaces.
- Reduced Flow Resistance The streamlined design of dual plate check valves minimizes pressure drop and resistance to flow, thereby improving the efficiency of the system as a whole.
- Fast and Reliable Closing Mechanism: The two plates close within very short time after the reverse flow is sensed and prevent any pump, compressor, or other delicate equipment from being damaged.
How Dual Plate Check Valves Work?
How a dual plate check valve works is quite simple:
- Flow in the Right Direction: When the fluid flows in the desired direction, the two plates are left open to fluid flow through the valve.
- Detection of Backflow: When the backflow exists or a pressure difference is available, the plates close automatically preventing backflow to the system.
- Automatic Operation: This system does not necessitate an outside supply of power or manual operation. This is, therefore, highly dependable and low maintenance.
Features and Benefits of Dual Plate Check Valves
- Better Flow Control: The design of the dual plate check valve has better flow control with minimal resistance. This helps to ensure that the flow in your pipeline systems runs very smoothly and efficiently.
- Space Saving: Because of their slimmer design, dual plate check valves take up less space, hence easier installation in tight spots as compared to the larger, traditional valves.
- Robust and Long Serving: These high-quality dual-plate check valves are built robust to resist most hostile environments that may have prevailed, thereby rendering long-term satisfactory performance.
- Reduces the Maintenance Work Needed: Due to this valve having the lowest number of moving parts in motion, one would rarely find issues related to higher maintenance costs with more down-time.
Applications of Double Plate Check Valve
Double plate check valves have been used considerably in many sectors where backflow prevention is required. Some of the sectors where these valves are used are as follows:
- Oil & Gas: Dual plate check valves prevent backflow of oil and gas pipeline and other devices from getting contaminated or failing in operation.
- Water Treatment: They are used in wastewater and water treatment facilities to stop tainted water or chemicals from flowing backwards.
- Chemical Processing: Dual plate check valves keep dangerous fluids from returning to systems in chemical facilities, avoiding contamination and preserving safe operations.
- Power Generation: These valves are used in power plants, especially in steam and cooling systems, to stop backflow that might harm sensitive machinery like pumps and turbines.
- Marine & Shipping: Dual plate check valves are usually installed in marine systems where it prevents the backflowing and pumps or engines will not malfunction.
Components of a Dual Plate Check Valve
- Valve Body: The primary structure, which houses all the internal parts of the valve, connects the pipeline.
- Twin Plates: Two plates work on hinges and close and open to allow or block fluid flow. The plates are designed to close automatically in case of backflow.
- Spring: In some models, there is a spring mechanism that helps the plates close faster when backflow is detected.
- Seat: The surface against which the plate seals when it closes to prevent backflow.
- Bolt and Nut: These parts hold the valve, ensuring it remains intact but giving easy access to the valve during service.
