Lug Check Valve

lug check valve enables the one-sided lugging of pipes. Dual plate Lug 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 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 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 Lug Check Valve by Chongqing Jeri Marine Equipment Co.,Ltd distinguishes itself by offering superior control in fluid handling operations. As an "automatic" valve, it is designed to open with forward flow and close with reverse flow, essentially using the pressure of the fluid passing through a system to operate. This makes it an indispensable component in maintaining the efficiency and safety of your piping systems. The Chongqing Jeri Marine Equipment Co.,Ltd Valve is an emblem of reliability, crafted from robust materials including cast iron, carbon steel, and stainless steel, ensuring durability and compatibility across a wide range of applications.

Structural Features:

Lug Check Valve adopt half semicircular disk, rotate around the shaft of the valve seat channel, since the valve's port is the flow line, flow resistance is small, suitable for low velocity and flow does not change often large diameter occasions, but not suitable for pulsating flow.

Simple structure with well sealed.

Easy to install, easy to replace the valve at any time.

Products Applications

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