Wear-resistant Ceramic Eccentric Rotary Valve

FUVALVE Ceramic Eccentric Rotary Valve Series with double eccentric design, torque sealing. Using double eccentric to produce cam wedge tightening effect to realize torque sealing. When closing, the C-type ball moves gradually relative to the seat, the tighter the clearance is, and the leakage grade of hard seal reaches VI. It is a typical spherical seal. And, it has functions of cut-off and adjusting; It can regulate and control throttling in slurry medium with abrasive solid content, fibrous fluid, high viscosity and scale-prone slurry.

Working principle：

Ceramic eccentric rotary valve, the valve body adopts an integrated eccentric design, and the single valve seat through shaft design.It has the properties of corrosion resistance, wear resistance, high temperature resistance and anti-crushing.

Structure description：

Due to the streamlined valve chamber design, when the valve is opened, the valve chamber is open and there will be no blocking or clogging.When closed, there is no material retention area in the valve chamber to avoid material crystallization and cannot be opened.

The introduction of advanced ceramic processing technology, the use of special processes, the unique self-lubricating properties of ceramics; can ensure ultra-light opening and closing torque.

The actuator connection is through the bracket interface, which complies with the ISO5211 size standard.

When the sealing pair is opened, due to the self-cleaning and moisturizing properties of the ceramics, the fouling and adhesion on the sealing surface can be cut off during the opening process with shear effect.

When the sealing pair is closed, the wedging effect caused by the eccentricity can automatically compensate for the sealing of the valve; it can extend the service time of the sealing pair for leakage.
