Lug retainerless dual check valve

Dual plate lug type with retainerless check valve’s body features a single cast body without pin retainer holes in the body. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications.

Lug body with ratainerless double disc check valves are also suitable for liquid, natural gas and steam service applications.

Compared to conventional swing check valve, lug type retainerless design dual plate check valves have the advantage of zero leakage toward outside, cost saving. It can be installed in any line orientation, superior seal performance. Dual plate lug type with retainerless check valves are designed in accordance to API 594.

Retainerless type without holes drilled in the body avoiding possible leaks to the external.
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.
Lug type valves are provided with threaded bolting holes in accordance with API 594,ASTM,JIS,ISO.

More Knowledge about TVCCL valve:

TVCCL Retainerless wafer check valve body features a single cast body without penetration through the body wall, eliminating the possibility of outside leakage; making it a preferable option for High-temperature work environment. Under the normal using situation, TVCCL guarantee retainerless type valve does not have any leakage problem on Body. Dual plate check valve with retainerless are available in 4 basic types: Wafer, Lug, Solid Lug, Flanged end, and in an extensive range of sizes, pressure classes and materials.
TVCCL check valve made of selected materials, each valve we made can offer the material certificate which according to BS EN 10204 3.1. Under the normal using situation, we can guarantee the TVCCL valve is more durable than the other manufacturers. And the performance is more reliable and practical. Using check valve under normal situation all can achieve the non-return effect. However, if the pipeline installation distance is less than 6~8 times the size of the valve, the life of the check valve may be shortened or the valve body and parts may be damaged.

More Knowledge about dual plate check valve:

Lug type retainerless type check valve has no screwed body plugs.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.
The Retainerless type is a type which body without pin retainer holes in the body. Retainerless type check valve use carrier and screw instead of retainer function to fix the pin. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications. Retainerless valves are also suitable for high-temperature liquid, natural gas, steam service applications. Retainerless type check valve all inserts/parts are all the same as Dual plate check valve, except for using carrier and screw to replace the retainer. Simply, Dual plate check valve is drill four holes through the body of the check valve to facilitate installation of a hinge pin and stop pin, but Retainerless can be fixed by carrier and screw and is no need to drill the holes outside of valve’s body. Model: TC8 Wafer or Double Door Check Valves have no through holes. The Retainerless special to use in industry, especially offshore or onshore pipelines, there is a tremendous concern for fugitive emissions and potential environmental concerns. Retainerless check valve design also provides higher integrity on high pressure, ensuring no concerns about leakage.
