Is there any direction for the installation of stainless steel flanged ball valve? In theory, the installation of stainless steel flanged ball valves has no direction. Whether it is a pneumatically driven ball valve or an electric ball valve and other ball valve products, there is no direction. However, in the actual application process, in order to avoid the leakage of the valve body and the valve cover, the valve The body is generally connected to the direction from which the material medium comes. Of course, if some stainless steel flanged ball valves are directional, arrow indications will be given on the valve body. If the installation is reversed, there is no way to ensure tightness.
Schematic diagram of installation direction of stainless steel flanged ball valve
Stainless steel flanged ball valves are structurally divided into two types: one-way sealing and two-way sealing. Obviously, the one-way sealing stainless steel flanged ball valve has a direction. cause production accidents. The two-way sealed stainless steel flanged ball valve is not limited by the installation direction.
The stainless steel flanged ball valve with manual control function has no direction, and the stainless steel flanged ball valve with the actuator has direction. V-shaped ball valves and eccentric hemispherical valves have directionality, and generally the flow direction of the medium is marked on the valve body. The floating ball valve and the fixed ball stainless steel flanged ball valve are bidirectional and are not limited by the installation direction.
In practical applications, the characteristics of the products supplied by each manufacturer should also be considered. The key is to see whether there is a flow direction indication on the stainless steel flanged ball valve body. If not, it is a two-way seal, regardless of the installation direction; if there is a flow direction indication , it must be installed in strict accordance with the direction prompts, so as to play the role of the stainless steel flanged ball valve.
