Product advantages

No cavity design structure

During the closing process, this structure can crush and aggregate the material attached to the valve ball, without causing the valve to lock up. With the increase of Pressure, the sealing effect is enhanced and the leakage risk is low.

Valve drive shaft design

The valve drive shaft is designed with multiple sets of PEEK bearings to effectively reduce torque and solve the problem of valve seat and valve core wear caused by high-frequency switch center offset.

Diamond spraying on valve ball and valve seat

The surface of the sphere and the sealing surface of the valve seat are hardened using diamond spraying technology. The coating and substrate belong to micro metallurgical bonding, effectively avoiding the peeling of the hardened layer during long-term operation.

Good corrosion resistance

Diamond coating has stable chemical properties and can withstand corrosion from most acids, alkalis, and salts, protecting the substrate material.

Excellent wear resistance

The wear resistance is 2-3 times that of ordinary hard alloys (such as tungsten carbide), greatly extending the service life of valves under harsh working conditions.
