Working Principle:
Compressed air forces the piston to reciprocate, achieving valve opening and closing.

The medium pressure acts on the valve seat, with minimal interference to the piston,

allowing the valve to open or close quickly. The improved internal structure of the valve

allows for better fluid flow and reduced pressure loss.

Advantages:

1.Compact size, beautiful appearance, long lifespan: Made of stainless steel valve body,

high-end appearance, corrosion-resistant. The piston and seal are integrated, simple

and reliable, with a unique structure ensuring that the axial seal is not affected

by lateral forces and eccentric loads, resulting in a longer sealing lifespan.

Can be installed in any direction.

2.Fast response, minimal pressure loss: The fluid flow in the valve body is better,

and since the medium pressure acts on the valve seat, the piston is hardly

affected by resistance, resulting in fast switching speed and minimal pressure loss.

3.Vacuum resistance: Excellent sealing performance, suitable for vacuum pipelines.

4.Anti-blocking: Particularly suitable for controlling media with particles, viscosity, and easy condensation.

5.Maintenance-free: Due to only having one moving part (piston rod),

without the traditional filler sealing components between the stem and

actuator in conventional valves, and without additional driving actuators,

the coaxial valve requires no additional maintenance.

Applications:
Machine tool cooling and lubrication, petroleum extraction and processing,

gas production equipment, powder metallurgy, high-pressure washing machines,

pressure grouting, blow molding machines, sewage treatment equipment,

foam equipment, high-pressure testing equipment, laminar cooling, vacuum equipment.
