VQ947H- 16 c V electric flange regulating pneumatic ball valve

Electric V VQ947H - regulating pneumatic ball valve With 16 c is a ball core v-notch fixed pneumatic ball valve, control performance is better in the pneumatic ball valve, flow characteristic is equal percentage, adjustable ratio of 100:1. The v-shaped incision and metal shearing action between the pneumatic valve seat, especially suitable for fiber, tiny solid particles and slurry medium. Electric V adjusting ball pneumatic valve core is in the shape of V can realize linear adjustment, wide adjustable range. When the pneumatic valve closing, v-notch produce wedge between shearing action with the pneumatic valve seat, both have the function of self-cleaning and can prevent the core ball stuck, especially suitable for the pipeline scaling freeze.



electric V adjusting characteristics of pneumatic ball valve:



1, the pneumatic v-shaped incision of the spool and metal seat before have shear effect, especially suitable for fiber, tiny solid particles and slurry medium.

2, with adjusting and reliable positioning capabilities, the approximate percentage, flow characteristic of the adjustable range.

3, v-type regulating pneumatic ball valve adopts pneumatic valve seat structure of plate spring loaded, pneumatic valve seat and the ball core won't produce the problem such as jam or from, reliable sealing, long service life.

electric V mechanism regulating pneumatic ball valve:



electric V adjusting ball special v-shaped opening of pneumatic valve and pipe flow form a cross section, can according to the size of the opening of the v-shaped ball core, to the flow of medium size and precise adjustment of the parameters such as pressure control, applies to adjust the bigger of the control system. Electric V regulating pneumatic ball valve does not need the other match servo amplifier, DC4 - input 20 ma, DC0 - 10 v or DC1 5 v related signal and power supply can control pneumatic ball valve operation, realize the medium pressure, flow, temperature, liquid level of various parameters, such as the precision of adjustment.
