Pneumatic regulating ball valve is a kind of orthogonal rotary valve, it with the valve positioner, proportional control can be realized, and the two five-way solenoid valve and control box, which can realize the switch control. Pneumatic V type ball valve core is designed with a special shaped v-notch, with precise closure properties and control functions, suitable for control occasions, with large rated flow coefficient, adjustable ratio is large, the sealing performance is superior, the compact structure, small size, vertical needle valve manufacturer horizontal installation, etc. Suitable for gas, liquid, solid granular media control. As there is no gap between valve core and valve seat is back, so have a lot of shear force and self-cleaning performance, especially suitable for containing fibrous or suspension of tiny solid particles and solids control.
Pneumatic regulating ball valve features:
1. Ball valve by V of the valve and actuator and other accessories. Advanced control valve is a quarter-turn structure.
2. Have excellent control characteristics: v-type valve has a inherent flow characteristics and that's at nearly the same percentage as high as 300:1 adjustable ratio. So V valves can be supplied in wide range of change of precise control.
3. Z large flow volume: because of its streamlined shape and full quarter-turn control, to make the volume of the Z value is extremely high, general ability particularly big, small flow resistance, so you can use the more economical and practical valve size smaller.
4. V valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure the valve has excellent sensitivity and speed of induction.
5. Z big reliable (safe) sex: the body as a whole structure, strong and durable, operation is not affected by the pipeline pressure, and can avoid the leakage of the valve body.
6. Superior metal seat sealing: v-type valve adopts metal valve seat, have buffet compensation function, and are excellent sealing performance and long service life. On the flow, the leakage of 10 or less - 6 x rated flow coefficient.
7. Strong shear capacity: v-type valve adopts metal hard seal structure, V and metal seated valve core in the process of turning, v-notch and valve seat can produce a strong shear to cut off the fiber, and 12 needle valve other impurities and self-cleaning function, avoid valve stuck phenomenon.
8. Pneumatic V type ball valve structure is compact, small light, convenient installation, easy maintenance.
9. Pneumatic actuators using piston cylinder and crank arm structure, output torque, small volume. Actuator adopt fully sealed waterproof design protection grade is high. Cylinder block USES the import mirror cylinder, oil free, small friction coefficient, corrosion resistance, with super durability and reliability. All drive bearing adopts boundary self-lubricating bearing without oil lubrication, ensure that the shaft does not wear.
