804 Pneumatic Balancing Valve

Technical Specification

Size: P, A interface size: G1/4"

S1, S2 interface size: G1/8"

Pressure Range:

S1 end set pressure: 0.02-0.4MPa, users can set according to actual working conditions, generally use filtered compressed air

S2 end sampling pressure: S1±0.01MPa (from the equipment working pressure) P, A two-end pressure: determined by the control pressure required by the valve connected to the balance valve, generally use filtered compressed air

Temperature Range: 0℃~ 100℃

Advantage：

The balance valve, which is highly sensitive to pressure changes of ±0.01MPa, can automatically control and switch without manual adjustments.

Working Principle

This valve controls the output of the air source at the A end by the pressure change at the S2 port (the pressure at the S1 port is constant), thereby automatically controlling the switch of the valve connected to it (for example: angle seat valve). This allows the device to automatically adjust with the change in working pressure, ensuring the stability of the device’s working pressure.
