ball valve

Pneumatic overview of v-type regulating ball valve:

Air is the new development of v-type regulating ball valve hard seal and seal four fluorine ball valve adjustment.It adopts plate spring loaded movable seat structure, seat and the ball will not produce air raw jam or out of v-type regulating ball valve, reliable sealing, long service life.V-shaped ball valve valve core is designed with special switch v-notch, the flow capacity is big, small pressure loss, with precise closure properties and control function, flow characteristic is approximate equal percentage.Open-close part adopts v-shaped ball lack of structure, completely solved the problem of the valve cavity easily sedimentary medium.

Pneumatic main characteristics of v-type regulating ball valve:

1, compact structure, small size, vertical horizontal installation, etc.
2, have excellent characteristics: v type ball 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, the maximum flow volume: because of its streamlined shape and full quarter-turn control, make the maximum volume is extremely high, flow capacity particularly big, small flow resistance, so you can use the smaller more economic and practical valve size.
4, v-shaped ball valve with double bearing structure, high mechanical stability, small starting torque, to ensure the valve has excellent sensitivity and speed of induction.
5, the most reliable (safe) sex: the body as a whole, strong and durable, operation is not affected by the pipeline pressure, and can avoid leakage of the valve body.
6, superior metal seat sealing: v type ball valve with metal valve seat, self-help 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, super shear capacity: v type ball valve with metal hard seal structure, v-shaped ball valve core and the metal seated in the process of turning, v-notch and valve seat can produce a powerful shear force to cut off the impurities such as fiber, with self-cleaning function, avoid valve stuck phenomenon.
8, optional the company production of pneumatic, electric and pneumatic external regulation, electric external regulation.
