Pneumatic V notch jacketed ball valve introduction
Pneumatic V notch jacketed ball valve is a kind of right-angle rotary structure of the control valve, which is composed of v notch jacketed ball valve and piston type double action or single action (spring return type) pneumatic actuator, Pneumatic V notch jacketed ball valve is used with positioner, which can achieve proportional regulation;Pneumatic V notch jacketed ball valve can be used with solenoid valve and control box to realize two-position cut off control.Pneumatic V notch jacketed ball valve spool design with special shape V-notch, accurate flow characteristics and control function, suitable for gas, liquid, solid particle and other medium control.Because there is no gap between the valve core and the seat rotation, so Pneumatic V notch jacketed ball valve has a great shear force and self-cleaning performance, especially suitable for the suspension containing fiber or small solid particles and solid particles of the working conditions of the automatic control system.

We are Pneumatic V notch jacketed ball valve manufacturer in size starts from DN15 x DN 40 (1/2″ X 1-1/2″) to DN150 x DN600 (6″ x24″).
The Jackets assure consistent valve Heating or Cooling of the process media to prevent crystallization or seizing of flow media. The Pneumatic V notch jacketed ball valve with very well design to help the high temperature steam or oil flow over the valve ball & body parts to keep the media liquid.

Pneumatic V notch jacketed ball valve Product features:
1. Pneumatic V notch jacketed ball valve to compressed air as the power, through the piston rack, gear mechanical drive valve stem, with angular stroke output torque rotation ball 0~90°, can complete the opening and closing action or adjustment action.Input 4-20mA current signal through the matching electric valve positioner to change the rotation Angle of the spool (0-90° arbitrary Angle) to adjust and control flow and other parameters.Precise control, small volume, light weight, small flow resistance, large flow coefficient, simple structure, good sealing performance.It is a valve with real high efficiency to control the process condition.
2. Pneumatic V notch jacketed ball valve with excellent regulation characteristics: V-valve with an approximate equal percentage of the inherent flow characteristics and up to 300:1 adjustable ratio.V-type valves therefore provide accurate control over a wide range of variations.
3. The maximum flow volume: because of its streamlined shape and full right Angle rotation control, the maximum volume is particularly high, the flow capacity is particularly large, the flow resistance is small, so you can use a smaller and more economical valve size.
4. Pneumatic V notch jacketed ball valve with double bearing structure, high mechanical stability, small starting torque, to ensure that the valve has excellent sensitivity and induction speed.
5. Maximum reliability (safety) : the valve body is a whole structure, strong and durable, operation is not affected by pipeline pressure, and can avoid leakage of the valve body.
6. Excellent sealing of metal seat: Pneumatic V notch jacketed ball valve adopts elastic movable metal seat, with self-compensation function, excellent sealing performance and long service life.In the flow direction, the leakage quantity is ≤10--5× rated flow coefficient.
7. Super shear capacity: Pneumatic V notch jacketed ball valve using metal hard seal structure, V-type valve core and metal seat in the rotary process, V-type notch and seat to produce a strong shear force, can cut off fiber and other impurities, and has a self-cleaning function, to avoid the valve stuck phenomenon.
8. Pneumatic actuator adopts piston cylinder and curved arm conversion structure, with large output torque and small volume.The actuator adopts fully sealed waterproof design with high protection grade.The cylinder body use mirror cylinder, oil-free lubrication, small friction coefficient, corrosion resistance, with super durability and reliability.All transmission bearings are lubricated with oil-free boundary self-lubricating bearings to ensure no friction damage to the transmission shaft.
