DN150 Fully Lined Silicon Nitride Rotray Cam Valve for Acetic acid catalyst solution

FUV940T 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 slury.

Product Characteristics
Ceramic Eccentric Rotary Valve is also known as Cam Flexible Valve because of its cam-shaped rotation track. The valve body is integrated structure, single seat and through-shaft design, which has the advantages of wear resistance, erosion resistance,high temperature resistance and anti-crushing.

Due to the streamlined valve chamber design, when the valve opens, chamber opens and expands, cam ball is detached from valve seat, and there will be no sticking or blocking; when the valve closes, there is no material detention zone in the valve chamber, which avoid material crystallization turning on unable to open.
It has self-cleaning function. When the valve is opening, cam spherical is tilted away from valve seat, and the fluid flushes sundries along the sealing surface totally. When the valve is closing, C-ball moves gradually relative to the valve seat, which can realize the shearing of the adhering sundries on the sealing pair to ensure the cleaning of the sealing pair, and the wear resistance of the solid C-type ceramic valve seat will not be damaged by
intercepted objects.

Its actuator connection is through the bracket interface, which meets the ISO 5211 size standard.
FUV940T Ceramic Control Partial Core Rotary Valve has the advantages of light switch, low friction, no contact between spherical surface and sealing seat when opening and closing, small torsion and flexible rotation.
When the sealing pair is opening and closing, there is shearing performance. Ceramics have self-cleaning and self-wetting properties which help to clean scales and adhesives on the sealing surface and maintain long-term tightness.
According to the wedge effect which created by eccentric core, the tighter the closure of C-ball and valve seat, the contact between seal pairs can be compensated by themselves.
Ceramic Ball and Ceramic Seal match perfectly and the best sealing effect is realized. It ensure V or above shutdown level and better regulation performance.
