Screw valve series
The plastic parts are connected by rotating locking structure which is safer and more reliable than the straight plug type
The mechanism seal adopts the side extrusion seal solves the end face deformation problem
The gear is driven by external teeth and high performance motor to avoid the problem of stuck internal teeth and the continuous running times can reach 60000 times
Full buckle design without a single screw
The problem of expansion and contraction of the old bellows is completely solved by adopting the dynamic seal of the tapered sleeve piston
Nut and screw adopt radial anti-lock structure high voltage on low voltage off more reliable
Valve seal bracket adopts guide positioning switch valve more smoothly no shaking
