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:

Lug type with full rubber lined check valve's body with full rubber lined can effectively reduce disc's leakage probability for the corrosion of seawater.
Bolt hole of lug type with full rubber lined check valve can be tapped according to client's requests to particularly customized.Dual plate Lug type check valve enables the one-sided lugging of pipes. Dual plate Lug type check valve has protruding lugs in the periphery of a body that provides passage to bolt holes that match with those in the flanges. In a lugged connection the valve is fastened directly to the pipe flange by connecting the pipe flange with bolts to the valve body also drilled with threads. Its tight seal and one-piece body prevents operating fluid leakage, allowing for safer more reliable operations. Because it has threaded bolts around the entire area, the lug valve is a safer option. Lug type dual check valve can be used on lines that provide replenishment to auxiliary systems where the pressure may rise above the system pressure. A dual plate Lug type check valve is combined with body, plate, pin and spring. Due to the short closing stroke of the disc and the spring loading, the water hammer is significantly reduced.

FAQ
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.
