More Knowledge about TVCCL valve:
TVCCL Full Lug type valve has lugs that are used to mount the valve to lugs that are attached the flanges on the ends of sections of pipe so that each length of pipe can be removed and replaced independently. Full Lug Type check Valve have the main advantage is you can disconnect any flange of the pipeline. Full Lug type check valves require different connections depending on the environment and area. TVCCL check valve has many choices of connections, generally wafer, flange and lug. Among them, the lug type is divided into two types, generally lug type check valve (TC6) and full lug type check valve (TC9).
The difference between the two is that the Lug type flange is hollow at the flange, so the weight is lighter; the full lug type check valve is solid to the flange, so the weight is heavier, but it is also stronger. Full Lug type check valves are also connected by flanges on both sides, so there is no flange thickness. For Full Lug type check valves, the flange thickness is equal to the face to face (FTF).
More Knowledge about dual plate check valve:
Solid Lug Type check valve also called Full Lug type check valve. It is named the Lug type is because the shape is like the ear. Full Lug type is suitable for the environment where the space is small, because the flange hole has tapping, it can save the space occupied by the nut and the cost of the nut. Full Lug check valve has the same advantages and installation with Lug type, just the shape is different. Full Lug type Check valve is threaded (Flange holes by tapping). Also, after tapping the holes, it only needs the bolt to install, it can decrease the spent of Nuts on the contrary. Clamped between flanges with bolting passing through the body of a valve. The full lug type wafer type check valve's design that one end of the line can be taken off without having an effect on the opposing side. This can be executed by using flanges, along with two sets of lugs (bolts) that don't utilize nuts since each flange features its own bolts. It's also important to note that you don't need to shut down the entire system in order to clean, inspect, repair, or replace a lug wafer valve.

- 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.we will email our Installation and maintenance instruction for your reference at first transaction.WCB/CF8/CF8M/CI/DI/B148 C95800(ALBC3) we usually have stock as above; However, to some special materials, like A8904A/CF3M…etc. We need evaluate if it need MOQ or not.NBR→Usually used in WATER & WASTEWATER TREATMENT.
