Balanced pneumatic stop valveWorking principle:
1. The control mode is pneumatic, and the air source pressure is 0.4~0.6 MPa. Set to power on and power off. It can also be set in reverse according to user requirements.
2. Valve open: press the valve open switch, the solenoid valve is energized. After triplets, after treatment, the air source will enter the cylinder rod cavity. Under the pressure of the air source, the piston will be pushed up, driving the valve up, and the valve will be opened.
3. Close the valve: press the lower close valve switch, the solenoid valve is de-energized, and the air source enters the rodless cavity of the cylinder after triple treatment. Under the pressure of the air source, the piston is pushed down, driving the valve flap down, and the valve is closed.
Balanced pneumatic stop valveStructural features:
1. The balance type pneumatic stop valve is S-shaped flow line, with pressure self-balancing structure, convenient opening and closing, low vibration, low noise, corrosion resistance and long service life. It can ensure convenient opening and closing under any pressure difference.
2. Frequent opening and closing under high pressure difference within the rated pressure range, tight and reliable sealing, to ensure zero leakage of the valve.
3.Balanced pneumatic stop valveUsing pneumatic device control, the system has fast response speed, can act accurately according to the control instructions, and can realize the remote control, centralized control and automatic control of the valve.
4. Maintenance and overhaul is convenient and quick.
