Product Description:
Check valves are mechanical valves 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. The mechanics of check valve operation are not complicated. 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. We manufacture check valves in conformity with ASME B16.34 standards. All valves are tested according to API 589 requirements. The marking is as per MSS SP-25 standards.
Tianqi valve is located in the "township of the Chinese pump valve" - Oubei town of Yongjia County, is a collection development, production and sales of valves and service in one of the modern enterprise, the company was founded in 2014, since the creation of technology innovation, the growing scale of.
