Screw valve series
Plastic parts use rotating locking structure, which is more safe and reliable than straight plug
The mechanism seal adopts lateral extrusion seal to solve the problem of end surface deformation
The gear adopts external tooth drive and high-performance motor to avoid the problem of internal tooth jamming, and the continuous operation times can reach 60,000 times
Full-card buckle design without a single screw
The conical sleeve piston dynamic seal is used to completely solve the problem of old bellows
Nut and wire rod use radial anti-lock structure, high voltage open, low voltage off more reliable
The valve seal bracket adopts guided positioning, and the on and off valve is more smooth, without shaking
