300LB Dual Plate Lug Type Check Valve,14 Inch 300LB Dual Plate Lug Type Check Valve,6A 300LB Dual Plate Lug Type Check Valve
Lug type dual plate check valve suitable for use in countries with a lot of earthquakes or in environments where there will be vibrations.
The dual plate lug type check valve only takes 15-20 minute completely dissemble and reassemble or less.
Seat Leakage:
Our products- dual plate check valve is tested to API-598 which has a metal to metal seat permitted seat leakage of 3 c.c./inch when use hydrostatic test. And if we use pneumatic test is according to API-598 which has a metal to metal seal permitted seat leakage of 700 c.c./inch.
In general, the flange holes of dual plate lug type check valves have tapping.
China 6A Dual Plate Lug Type Check Valve Manufacture
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.
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.
Lug type valves are provided with threaded bolting holes in accordance with API 594.
Features
- 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 dual plate check valve:
CF8.CF8M – literally,”stainless steel” is the steel rusty hardly. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless Steel are devided into many serials. Most commonly are A351 CF8,A351 CF8M,A351 CF3M…etc.
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
