Eccentric rotary valve

Eccentric rotary valve, also known as the deflection cam valve, the eccentric ball plunger control valve. It has an eccentric rotation
Spool, when the control valve to close. When closed, the valve body of the flexure arm to generate flexural deformation, so that the spherical ball plunger and the valve seat of the spool close
Contact, good sealing performance. Eccentric rotary valve features are as follows.
Erosion resistance. Valve body and cover the whole cast, wide operating temperature, in a 40 to 450 ° C, working pressure can 10MPa.
Wear long service life. Its contact with the valve seat ring can be minimized the eccentric ball plug in the open, and therefore, due to rotation caused by the wear is small, it also reduces the friction, improving the dynamic characteristics of control valve, and to extend the useful life of the control valve air cylinder manufacturers
3 adjustable ratio. Full cavity up to 100:1; 60% shrinkage cavity up to 60:1; 40% shrinkage cavity of up to 40:1.
4 good seal. Spool flexure arm deflection of the valve body can be pressed against the seat of the sealing ring to ensure a good seal, the standard
The leakage amount is less than 0.01% ℃.
5. Flow capacity. The flow capacity of up to 1.2 times the same diameter seat valve.pilot valves
Flow characteristics close to the modified parabolic characteristic change in the direction of flow does not change the flow characteristics.
7 dynamic stability. Only requires less torque to tightly closed. The change of the flow direction, the fluid on the valve body the role of torque cancel each other, nor the valve plunger undercut phenomenon, therefore, the dynamic stability of the plunger valves and butterfly valves.
8 in the valve body lining a variety of corrosion-resistant or wear-resistant lining material to adapt to run under a variety of operating temperature and pressure conditions, can be adapted to the control of corrosion and fluid containing particles.
9., Light weight, small size, flexible installation, versatility.solenoid valve actuator
