Special seat eccentric adjustable control valves
features
Traditional valve is through the valve core or V hole to change the flow characteristics and flow, while ZAJV electric eccentric control valve is through special seat to change flow characteristic and the flow, this is the biggest difference of this valve. It achieves the accurate adjustment. After many years' research, high-precision computer control is necessary. This valve is superior to the traditional V type control valve, eccentric rotary valve design, is the best alternative products, are the domestic origination.
A variety of seat for selection. This valve uses laser cutting to achieve required shapes and sizes to adapt and meet the requirements of different customers.
Eccentric cavity and eccentric valve core, can overcome the large torque, meantime in the movement process, the core and the valve seat separated and not contact, with small wear, long service life. Bonnet and body integration, reducing one leak point.
The same size of the Cv value of 3 kinds above, just achieved by changing the seat, reducing inventory management, achieve production of standardized,
All valve components adopt modularization design, easy to change, Bonnet and body integration casting, reducing leak point, Super light thin exteriorcharacteristic, is the important innovation to traditional valve, Valve disc, seat adopt advanced processing technology, has good wear resistance and corrosion resistance. Through the seat to accurately adjust flow and characteristics of flow, There are various options of seat can meet the special requirements of customers,
