How to choose common accessories for pneumatic ball valves?
In the previous article, we introduced the role of common accessories for pneumatic ball valves. Today we mainly talk about how to choose these common accessories.
When installing pneumatic ball valves, in order to meet their different requirements in different pipeline systems, it is necessary to select accessories with different specifications, also known as pneumatic components, such as pneumatic head types, solenoid valve requirements, filter pressure reduction Valves and limit switches, etc., the following are the points that need to be paid attention to when selecting their pneumatic components and accessories:
1. The choice of pneumatic head. When selecting a pneumatic head, first determine whether to use a single-acting pneumatic head or a double-acting pneumatic head, and then you can select a pneumatic head that meets the output torque according to the valve's operating environment, the pressure of the air source, and other parameters.
2. The selection of solenoid valve mainly considers whether its pressure range, circulating medium, flow coefficient, working temperature, explosion-proof requirements and voltage meet the needs of pneumatic valves.
3. The pressure range, working temperature, circulating medium, filter element accuracy and drainage device should be paid attention to when selecting the filter pressure reducing valve.
4. Selection of limit switch. Choose whether the color of the position indication of the limit switch meets the requirements, whether the feedback mode is inductive or mechanical, and whether its explosion-proof level meets the requirements, etc.
The above are the matters needing attention when selecting common accessories such as pneumatic components of pneumatic ball valves.
