Lug type dual check valve, Lug wafer check valve

Lug type valves are provided with threaded bolting holes in accordance with API 594.

Check valves, also known as non‐return, reflux or one‐way valves are automatic valve types that do not require any manual or electrical intervention to open and close.

Check valves are used to allow flow in one direction only and prevent the reversal of flow. They are also used to protect the system and it’s components from water hammer and pressure surges.

Applications

  • Lug type check valve is suitable for a country, which has high-frequency earthquake. Alternatively, the pipe has violently impact and shake often.
  • Dual Plate Lug Type Check Valve is suitable for small pipelines and high temperature and high-pressure environment
  • Dual Plate Lug Type Check Valve can be applied to various environments such as water, steam, oil, strong acid oxidizing fluid and urea.
  • Lug type check valve is fastened directly to the pipe flange by connecting the pipe flange with bolts to the valve body also drilled with threads.
  • Dual Plate Lug Type Check Valve is a good solution whenever required compact dimensions and reduced weight.
  • Dual Plate Lug Type Check Valve is suitable for use in clean, dirty and seawater applications.
  • Lug type check valve is installed above ground in order to reduce congestion.

More Knowledge about TVCCL valve:

TVCCL Dual plate Lug type check valve has a retainer type (TC6) and retainerless type(TC8-2) design. Lug type can make lining rubber inside the body, full rubber lug type check valve (TC7) can satisfied with sea water and high concentration brine…etc. full rubber type could be suitable to use in the media which corrosive easily. Since the length of lug wafer check valve is shorter than the general check valve, make it more suitable for places with installation space restrictions. Lug type check valve’s flange hole is by tapped, so it’s not like flange type, one flange hole needs two nuts, can also save the cost of nuts.

More Knowledge about dual plate check valve:

Dual plate check valve lug type 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.
