V type pneumatic ball valve is the new development of the hard seal, PTFE seal ball valve. It uses a spring loaded movable seat structure, valve seat and ball will not produce V type pneumatic ball valve (13) raw waste or from the card and other issues, reliable sealing, long service life. V type ball valve core is designed with a special type of V type gap, flow capacity, pressure loss is small, and has the exact characteristics of the closure and control functions, flow characteristics, such as the approximate percentage. Opening and closing pieces by V segment structure, completely solve the problem of cavity deposition of medium valve.
Pneumatic V type ball valve is a right angle rotary valve, which is composed of GT pneumatic piston actuator (single or double effect) and V type ball valve is composed of two parts. Its sealing formalism has two kinds of soft seal and metal hard seal. The pneumatic V type ball valve is a right angle rotary structure, when the spool rotates relative to the valve seat has the strong effect of shearing, especially suitable for medium and small particles with fiber control. The company is widely used in petroleum, chemical, electric power, papermaking, metallurgy and other industries.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
3.1 valve body:

3.2 valve assembly:
Spool type: V type spool
Flow characteristics: equal percentage characteristics
Material: ICr18Ni9Ti, oCr18Ni12Mo2Ti
The seat material: tetrafluoroethylene, special PPL, metal seat.
Adjustable ratio: 350:1
1, compact structure, small size, vertical and horizontal installation, etc..
2, with excellent adjustment characteristics: V type ball valve with an approximate percentage of the inherent flow characteristics and the 300:1 of the adjustable ratio. Therefore, V type valve can be in a wide range of changes to provide precise control.
3, the maximum flow capacity: because of its streamlined shape and full right angle turn control reasons, the maximum volume is particularly high, especially large capacity, small flow resistance, so it can use a smaller valve size is more economical and practical.

4, V type ball valve with double bearing structure, high mechanical stability, low starting torque, to ensure that the valve has excellent sensitivity and induction speed.
5, the maximum reliable (safety): the body as a whole, strong and durable, the operation is not affected by the pressure of the pipeline, and can avoid the leakage of the valve body.
6, metal seat of the superior sealing: V ball valve using a movable metal seat, self compensation function, and has superior sealing performance and long service life. In the flow, the leakage is less than 10-6 * rated flow coefficient.
The shear capacity of 7, super: V type ball valve adopts a metal seal structure, V type ball valve core and metal seat in the process of rotation, V notch and the valve seat to generate a strong shear force to cut off the fibers and other impurities, and has self-cleaning function to prevent the valve stuck phenomenon.
