working principle;
YH38... series; The working principle of liquid and gas solenoid valves is pilot operated and normally operated
There are two working forms: open or normally closed. When powered on, the electromagnetic force first opens the pilot hole, and the pressure in the upper chamber rapidly drops around the closing component
Create a pressure difference of up, down, and up, and the fluid pressure pushes the closing member to move upward, causing the valve to open. When the power is cut off, the spring force closes the pilot hole
The inlet pressure quickly enters the upper chamber through the bypass hole, balancing the pressure difference between the upper and lower chambers of the closing member. Under the action of the reset spring force, it pushes
Move the closing component downwards to close the valve. The normally open principle is exactly the opposite.
Electromagnetic working conditions;
1. Environmental temperature- 10/+50ºC
2 . Relative humidity; 5%/85%
3 . Power supply voltage; AC24V
Installation precautions;
When installing the solenoid valve, the solenoid coil should be facing upwards and kept in a vertical position. If conditions do not permit
When inclined at 35 °, the arrow on the valve body should be consistent with the flow direction of the pipeline, and it should be installed in an exposed position
Rainproof and splash proof measures should be taken in the sky.
2. The fluid temperature must be lower than the calibration temperature of the solenoid valve.
When the fluid cleanliness is not high, especially when particles and ribbons are mixed in, it should be installed in front of the valve
Filter.
5. When solenoid valves are used in systems that operate continuously for a long time, a bypass device should be installed for easy maintenance.
