The installation of pneumatic ball valves in the equipment depends on the specific conditions of the equipment. Pneumatic ball valves also have different models. Generally speaking, pneumatic ball valves have no direction, but if they are installed incorrectly, they may cause leakage of the equipment and eventually lead to Production cannot be guaranteed. Practice has proved that in order to prevent leakage of the valve body and bonnet of the pneumatic ball valve, the pneumatic ball valve is usually connected in the direction of the material medium. To make the pneumatic ball valve have directivity, an arrow indication will be given inside the pneumatic ball valve. If the pneumatic ball valve is installed in the opposite direction, the sealing of the pneumatic ball valve cannot be guaranteed.
1. One-way pneumatic ball valve
From the structural point of view, pneumatic ball valves are divided into one-way pneumatic ball valves and two-way pneumatic ball valves. Obviously, one-way pneumatic ball valves have directions. If the one-way pneumatic ball valves are installed reversely, the sealing of the equipment cannot be guaranteed, and it may even cause Production accidents cause equipment failures and become unusable.
Two, two-way pneumatic ball valve
The double pneumatic ball valve is not restricted by the installation direction. Two-way ball valve has no direction, plus actuator has direction. V-shaped ball valve, eccentric half ball valve, has directivity, usually write the flow direction of the medium on the pneumatic ball valve. Floating and fixed ball valves are two-way structures, which are not restricted by the installation direction. In fact, the characteristics of the products supplied by various manufacturers should also be considered. The key is to see whether there is a flow direction indicator in the pneumatic ball valve body. Otherwise, it is a two-way seal and does not consider the installation direction. The role of.
