Features
The self-sealing stop valve is characterized by medium backflow (high-in and low-out), with dual functions of cut-off and check-off. The valve cover and the valve body are self-sealing structure. When closed, the self-pressure is 100% sealed. The valve is designed to be double-sized. The valve core solves the problem that the pressure difference is large and the opening is difficult. The special alloy of valve seat and valve core welding has wear resistance and toughness. It adopts taper seal and linear sealing surface. Under the condition of large temperature difference, it will not deform and is not easy to crack.
