Quick-closing valve series
The spring is built inside the mechanism, effectively saving the channel space and more smooth airflow.
Full-card buckle design without a single screw.
Using the new spine and claw structure, the valve time is shorter, the valve> 0.1S.
National invention and many other patents.
The national explosion-proof certification, international IEC, EU AETX certification.
Using the piston type sealing mode, will not seal more reliable, to solve the mechanism shrinkage and expansion problems.
