What is a pneumatic valve and what is the function of pneumatic valve A pneumatic valve is also known as directional control valves, the major function of a pneumatic valve is to switch airflow. These valves are capable to maintain the pressure. The range of pneumatic valves is vast and there are many categories of pneumatic valves.
Pneumatics are also used in control valves, pneumatics has many applications in different industries. It also has other applications such as dentistry, construction, and mining.
The pneumatic actuator uses compressed air as the power source, and the movement of the piston drives the crank arm to rotate at 90 degrees, so that the valve can be opened and closed automatically. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, cardan shaft.
{keyword},Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve.
{keyword}.The disc of the butterfly valve is that the disc has a shaft rotating on the position of the valve seat. The angle of the rotation determines the opening and closing degree of the valve.
{keyword},Most gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
