Description & Features

Titanium Alloy TA2 Check Valve that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow closes the valve. Most check valves contain a ball that sits freely above the seat, which has only one through hole. The ball has a slightly larger diameter than that of the through hole. When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. Once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow.

● Simple structure, small volume, light weight.

● The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.

● Tight and reliable, Mainly used to connect or cut off the medium in the pipeline, can be used in petroleum, natural gas pipeline and other industrial USES.

● A wide range of applications, from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.This type of valve shall generally be installed horizontally in the pipeline.

● Products can withstand high and low temperature, high pressure, corrosion resistance, and stable sealing performance.
