The characteristics of the pneumatic V type pneumatic valve adjustment and selection

Pneumatic V type pneumatic valve adjustment: is a kind of pneumatic valve seat adopts metal, or metal for ptfe seal with the rotation of the pneumatic valve, it has the advantage of the pneumatic valve and control characteristics of pneumatic valve combined into an organic whole, can be used to adjust the pneumatic valve, pneumatic valve can be shut off again cut off. Again due to the shear function, and so are more suitable for medium of the operation condition of the particles. Pneumatic V pneumatic valve is a quarter-turn structure control pneumatic valve, pneumatic valve can be divided into pneumatic V adjusted and pneumatic V cut off the pneumatic valve. It with pneumatic valve positioner, proportional control can be realized. With two five-way solenoid pneumatic valve and control box, which can realize the switch control. Pneumatic V type pneumatic valve valve core is designed with a special shaped v-notch, with precise closure properties and control functions, pneumatic V pneumatic valve is suitable for a variety of control occasions, compact structure, small size, tight horizontal installation, etc. Pneumatic actuators with double acting and single acting ( Spring return) , the pinion and rack drive; Pneumatic valve adopts series of large diameter AW pneumatic actuator fork type transmission, reasonable structure, large output torque, a double-acting and single acting.


pneumatic V regulating pneumatic valve's main features are:


( 1) Pneumatic V pneumatic valve by pneumatic valve and actuator and other accessories. Is a quarter-turn structure control pneumatic valve. V pneumatic valve does not need to repair for a long time, a longer service life.
( 2) Stable adjustment characteristics: pneumatic V pneumatic valve has an approximate percentage of inherent flow characteristics and up to 300:1 adjustable ratio. So pneumatic V pneumatic valve can provide accurate in wide range of change control.
( 3) Maximum flow volume: because of its streamlined shape and full quarter-turn control, make the upper limit of volume is higher, great capacity, small flow resistance, thus can use smaller budget pneumatic valve size.
( 4) Pneumatic V pneumatic valve adopts double bearing structure, mechanical stability, high starting torque is small, the pneumatic valve has good sensitivity and speed of induction.
( 5) Stability: pneumatic valve body as a whole structure, the operation is not affected by the pipeline pressure, and can stop the leakage of pneumatic valve body.
( 6) Metal pneumatic seat sealing: pneumatic V pneumatic valve adopts pneumatic metal valve seat, with the help of the compensation function, and are excellent sealing performance and long service life. On the flow, leakage 10 rated flow coefficient.
( 7) Strong ability of shear: pneumatic V type pneumatic valve adopt metal hard seal structure, pneumatic V type pneumatic valve core and metal seat in the process of turning, v-notch and pneumatic valve seat to create a strong shear force to cut fiber impurities, such as with self-cleaning function, stop pneumatic valve stuck phenomenon.
( 8) Pneumatic V pneumatic 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, cylinder block USES sophisticated mirrors, oil free, small friction coefficient, corrosion resistance, strong resistance to usability and stability. Transmission bearing adopts boundary self-lubricating bearing without oil lubrication, the drive shaft friction losses.
