Is the size of pneumatic battery valve universal? How to adjust it?

The size of pneumatic battery valve is not universal and can be adjusted by adjusting the pressure of gas medium. According to relevant data, the specifications of pneumatic battery valves are 24v and 12v, which are not universal. It can be adjusted by adjusting the pressure of the gas medium. Electromagnetic pneumatic valve uses the magnetic field generated by electromagnetic coil to pull the valve core, thus changing the on-off of the valve body. When the coil is de-energized, the spool will retract under the pressure of the spring.
