The American standard stainless steel ball valve's actuator work drives the valve body to open and close quickly, and the speed can be cut off within seconds. American standard stainless steel ball valve is mainly divided into three types: single acting, double acting and regulating type, which can be used as throttle regulating flow. At the same time, with the control box, the switch control can be carried out in the remote control room. Its sphere is floating. Under the action of medium pressure, the sphere can produce a certain displacement and press tight on the sealing surface at the outlet end to ensure the outlet end seal. The structure is simple, the sealing performance is good, and the load of the ball body to the working medium is all transmitted to the outlet sealing ring. The selection of the sealing ring material can withstand the working load of the spherical medium, and the structure thereof is widely applicable to the medium and low pressure ball valve.
 
    American standard stainless steel ball valves have fireproof and anti-static devices. The valve stem is designed to prevent blowout. It can prevent the valve stem from being sprayed out of the valve body due to improper operation. It can be used with the connection plate of various driving devices, and the position adjustment is convenient. When replacing or installing the actuator online, the position of the hole can not be seen clearly, which is convenient for the adjustment of the limit device of the actuator. For the valve with the welded end, the end material of the valve can be adjusted according to the material grade of the user to ensure the strength of the material. Adaptability and weldability, the valve stem is connected to the handle through flat keys or splines or deeds. It is versatile and easy to assemble and disassemble. It can be made of oil sand or synthetic diamond material of various materials. American Standard Stainless Steel Ball Valves The base material of the valve seat should be made of stainless steel with a linear expansion number close to that of the housing material. The hardening treatment of the sealing surface can also be carried out by manual surfacing or plasma spray welding of hard alloy.
