Pneumatic v-type regulating ball valve features overview and application

Pneumatic v-type regulating ball valve is a quarter-turn structure of rotary type regulating ball valve. By installing the valve positioner can realize proportional control. Pneumatic v-type regulating ball valve valve core is designed with a special switch v-notch, can make the valve flow capacity increase, pressure loss is small, the valve cavity no deposit medium, and the valve seat relative rotation to produce shear force, prevent card dead, and provide accurate control function. Pneumatic v-type regulating ball valve is for use in Class150 ~ 600, PN1.6 ~ 10.0 MPa, working temperature 200 ℃ or less various piping, suitable for gas, liquid and solid particles of the medium such as control. Due to the valve core and valve seat are no clearance rotary, so have a lot of shear force and consecrated themselves performance, especially applicable to contain fibrous or have small solid particle suspension and solid state granular control. This product can be widely used in oil, chemical industry, paper making, power, metallurgical, pharmaceutical, environmental protection and other automatic control system.

Pneumatic v-type regulating ball valve features:
1, have excellent control performance: V ball valve has a nearly the same percentage of the intrinsic flow feature and as high as 300:1 adjustable ratio. Therefore V type valve can be in wide width range to provide accurate control.
2, maximum flow capacity: because of its streamlined appearance and full quarter-turn control, because the maximum volume is extremely high, flow capacity particularly big, small flow resistance, so can use smaller more economic and practical valve size.
3, maximum reliable (safety) sex: the body as a whole, durable, operation from line pressure influence, and can avoid the leakage of the valve body.
4, super shear capacity: V ball valve mining has a metal hard seal structure, V ball valve core and metal seat in turning process, V notch and seat produce a powerful shear force can cut fiber impurities, and have consecrated themselves function, avoid valve card dead phenomenon.
5, metal seat is superior sealing: V ball valve using metal valve seat, self-help compensation function, and has the superior seal performance and long service life. In the flow, or less leakage 10-6 × rated flow coefficient.
6, compact structure, adopts double bearing structure, mechanical stability performance is high, small volume, convenient in installation.
7, don't take any pipe joint of monolithic body, so do not suffer a pipe or bolt stress influence, and because the body without any pipe joint, the pressure shell not be pressure "mutation" influence.
8, has a V type body, even in small flow or high viscosity medium, but also in the whole range range, guarantee the accuracy of control.
9, leakage-proof durable seat in its outer diameter place lining with stainless steel inner core PTFE cup or type O ring, seat with section larger cobalt tungsten carbide is made through a alloy ripple spring further enhance the seat structure.
10, when the valve is closed, V notch and seat occurs between wedge shearing action, and both has sanctified function and can prevent the ball core card dead, especially suitable for pipeline scaling freezing or contain fiber and particle solid occasion.
