◎Excellent sealing performance, using metal bellows as the key sealing component, with its lower end welded to the valve stem assembly and its upper end connected to the
Plate welding forms a metal barrier to prevent fluid medium leakage and achieve zero
leakage of the valve stem
◎The main components such as the valve body are made of forged steel with high structural strength, resulting in a more uniform structure, better density and strength integrity, and dimensional errors small, with better performance compared to castings, able to withstand higher pressure and temperature
◎ Easy and reliable operation
The dual guarantee of long service life with corrugated pipe sealing and packing sealing
reduces the risk of leakage and lowers the frequency of maintenance; Valve body and
◎The minimum wall thickness design of the valve cover meets the requirements of relevant standards, ensuring the strength and rigidity of the valve under harsh working conditions such as high temperature and high pressur

Stop Check Valve, A multi-purpose valve that functions as both a stop valve and a check valve. Its structure is similar to that of a globe valve, but the stem and disc are not fixed. When the stem is lowered and the disc is pressed tightly on the seat, it acts as a stop valve; After the stem rises, the check valve acts. On lines that require both a stop valve (or gate valve) and a check valve (such as the outlet of a water pump), using a stop check valve can save installation costs and space. In the opening and closing process, because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, it is more wear-resistant.
The Silenct Check Valve is a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. Belonging to an automatic valve, its main function is to prevent medium backflow, prevent pump and drive motor from reversing, and prevent the release of container medium. Check valves can also be used on pipelines to supply auxiliary systems where the pressure may rise above the system pressure.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
