More Knowledge about TVCCL valve:

TVCCL full rubber type check valve’s material is divided into two choices, NBR and EPDM. Before use, you must pay attention to the temperature of the medium and whether there is a granular object in the medium. Because the rubber can't afford the high temperature and low temperature as well, it is recommended to use it at normal room temperature to avoid the rubber falling off or deforming; and owing to the rubber is unbearably worn, It is not recommended to use the full-rubber type check valve in the cement or the medium which has the presence of particulate matter in pipelines. The installation method is the same as the dual plate check valve. The only difference is that the flange surface of the full rubber type check valve is also covered with rubber, so it is not necessary to add a gasket to fix it.
The Full Rubber type check valve’s inner covering rubber, the medium and the body material are not in direct contact, and the rubber is separate into the medium and the valve body material, thereby achieving the acid resistance and corrosion resistance. The Full rubber type check valve body internal adopts an all-rubber design, which is not easily deposited or produced. And it also reduces the maintenance cost, but the disadvantage is that the rubber is not suitable to keep for a long-time in outside, even if the quality of the rubber is high, the aging phenomenon cannot be avoided.

More Knowledge about dual plate check valve:

The Dual plate wafer type check valve with full rubber, as the name implies, it is the wafer type check valve which lined the rubber inside the body, also known as a full lining check valve. Full rubber check valve is lined with rubber, which has a better waterproof and slip-proof effect than the other valves. Without any leakage under normal circumstance. Commonly used in environments with high salinity content, desalination or coastal areas. Due to the insulating function of the rubber material, it has become the first choice for users of the above-mentioned environment. Full rubber check valve’s body is covered with rubber, so the valve body material can be selected from the lower price, such like DI material or WCB material, and the price is lower than AL-BRONZE or Duplex and Super Duplex Stainless Steel.

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.
