1. Features:

1. The air pressure reducing valve is used under the condition that a certain air pressure needs to be maintained in the general pneumatic control system and general pneumatic pipeline.

2. The air pressure reducing valve, also known as the pneumatic pressure regulating valve, is an overflow type direct-acting air pressure reducing valve, which directly controls the output pressure by operating the pressure regulating spring by the handle, and can achieve stepless pressure regulation within the specified pressure regulation range. And keep stable at the set value.

3. When the downstream pressure of the air pressure reducing valve (pressure at the output port) exceeds the set pressure, the overflow valve begins to overflow, so this series of products should not be used directly for harmful gases that are not allowed to leak into the air.

4. The air pressure reducing valve adopts a balanced intake valve, so the change of the input pressure in the range higher than the set pressure has little effect on the output pressure.
