A check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve. When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. Depending on the valve type, the closure mechanism is different. Unlike other valves, they do not need a handle, lever, actuator, or human to correctly work.

Dual plate check valve are available in 4 basic connection: Wafer, Lug, Solid Lug, Flanged end, and in an extensive range of sizes, pressure classes and materials. Material required other than standard upon request

More Knowledge about TVCCL valve:

TVCCL check valve made of selected materials, each valve we made can offer the material certificate which according to BS EN 10204 3.1. Under the normal using situation, we can guarantee the TVCCL valve is more durable than the other manufacturers. And the performance is more reliable and practical. Using check valve under normal situation all can achieve the non-return effect. However, if the pipeline installation distance is less than 6~8 times the size of the valve, the life of the check valve may be shortened or the valve body and parts may be damaged.

More Knowledge about dual plate check valve:

Aluminum bronze is very hard, wear resistance, and light weight, with excellent tensile strength, even in high temperature environment can still maintain these excellent physical properties.
It’s the most commonly used in applications where their resistance to corrosion makes them preferable to other engineering materials. Suitable for use in general sea water-related service and do not need MOQ.
The dual Plate Check valve is an automatically opened valve that only allows the medium to flow in the same direction and prevents reverse flow. Automatically open and close when there has pressure generated, no need to handle or other actuation control. Under the action of the pressure flowing in the same direction, the discs are opened, so that the medium can flow in the pipeline; conversely, when the medium flows in the opposite direction, the pressure generated by the medium and the weight of the valve discs act on the seat. When the valve is closed, the check valve will cut off the flow, thereby achieving the effect of backstop and media backflow. Its main function is to prevent backflow of the medium, prevent the pump and drive motor from reversing, and release the container medium. TVCCL's check valve is quickly closed due to the valve flap, which can quickly achieve the effect of the backstop and can effectively reduce the occurrence of water hammer.

TVCCL Check Valve is a dual plate check valve that conforms to API 594. TVCCL is known as one of the leading manufacturers of Valve in Taiwan since we established.A check valve, non-return valve (NRV) or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Simply put, a check valve allows flow in one direction and automatically prevents back flow (reverse flow) when fluid in the line reverses direction. Ceck valve are one of the few self-automated valves that do not require assistance to open and close. Unlike other valves, they continue to work even if the plant facility loses air, electricity, or the human being that might manually cycle them. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. Check valves are found everywhere, including the home. If you have a sump pump in the basement, a check valve is probably in the discharge line of the pump. Outside the home, they are found in virtually every industry where a pump is located. There are various types of check valves used in a wide variety of applications. Basically, check valve is doing the function of avoiding reverse flow no matter what the type is.
Taiwan Valve Centre Co.,Ltd. is the professional dual check valve manufacturers in the Taiwan. This information concerning the installation and operation of TVCCL Wafer Style, Dual Plate Check Valves. To ensure efficient and safe operation of TVCCL Dual Plate Check Valves. This manual is general in nature and is not meant to take the place of an on-site, process engineer or pipe fitter.Installation procedure 1. Check the dual plate check valve to make sure the pressure and duo chek valve materials are correct for the application. 2. Make sure the pipe line has enough support to prevent vibrations and load weight from damaging the check valve. 3. Make sure pipes are aligned. 4. Make sure pipe flanges and doule door check valve sealings are clean from any debris.Check all surfaces for cleanliness and other visible sign of foreign matter as the internal surfaces/parts must be clean and free of debris before installation 5. Before installing the valve, it is important to know the flow direction. The flow direction shall be the same direction as the arrow that can be found on the side of the valve. If the valve is installed in the wrong direction the flow will stop. 6. Fix the valve with the bolts without tightening them. 7. Use crosswise bolt tightening to ensure a fixed installation. Other bolt tightening sequences may affect the installation.Dual plate check valves should be installed a minimum of 6 pipe diameters downstream of any piping component (elbow, Tee, Valve, etc.) to allow the flow to stabilize. There should also be a minimum of 2 diameters of straight pipe downstream of the valve before the next fitting to allow for pressure recovery.
