Dual Plate Lug Type Check Valve
Lug type dual check valve, Lug wafer check valve
The dual plate lug type check valve only takes 15-20 minute completely dissemble and reassemble or less.
In general, the flange holes of dual plate lug type check valves have tapping.
Lug type check valves are furnished with thru-hole bolting in accordance with ASME, JIS, ISO, MSS and AWWA…etc. Threaded bolt holes are available when specified.
A metal-to-metal leakage rate of 1cc/minute/inch diameter can be provided at no extra cost if specified with customer enquiry/order.
Note: API 598 specifies 3cc/minute/inch diameter with water.
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.
- Lug Type check valve's OD usually do not need machining, and we do tapping on bolt hole.
- While small size lug valve be installed, the piping flange does not have the problem of installation.
- Do not have install problem of pipe flange, especially for small size.
- Even for small size, still has bolt to set each bolthole.
- Bolt hole to be tapped according to client's requests to particularly customized.
- Retail acceptable.
- Beautifully packaged.
- Customized special valve.

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.
