Dome valve

Product description

YDF-A dome valve is our company to introduce advanced foreign special powder valve technology, and in accordance with domestic and foreign thermal power and water glass manufacturing systems and other systems of the actual transmission of powder and professional development, with a number of patented technologies. New product structure, excellent performance and stability, good sealing performance, automatic pressure compensation, protective seat design, erosion resistance, open and close rotary zero friction, long service life. Products with strong automatic control of centralized control with the computer can be combined to meet the automation requirements of modern pipelines, widely used in thermal power, cement manufacturing, glass manufacturing and thermal power transmission systems such as powder control, start Closed off the flow of use. 
 YDF-A dome valve is widely used in thermal power plants, pneumatic ash, power plant dust, and feeding, discharging system, it has the advantages of simple structure, less wear and tear, small torque.

 Structural features
1, the valve adopts inflatable ring, valve opening and closing, no contact between the spool and the seal. 
2, when the valve is switched over, the ring inflated to achieve elastic deformation of the seal.

3, the valve is in place switch, and the switch signal can be sent to the PLC for remote control.

4, the valve cylinder drive, easy and quick switching.

5, the structure is simple, directly driven by the cylinder valve to open and close the valve state, easy maintenance.
