Product features

The electric cage type regulating valve is a kind of pressure balance regulating valve. The valve body adopts the pilot valve core guided by sleeve. The valve core has a balance hole to reduce the unbalanced force. It has large adjustable ratio, small vibration and good interchangeability. It can be used in most single seat and double seat valve applications, but it is not suitable for particles and dirty media. It is the most widely used type of control valve.
 Structure of electric cage control valve
Features of electric cage control valve:
 
There is a window on the electric cage control valve to determine the flow rate and flow characteristics. The unique symmetrical porous cage valve disc can effectively control the noise and cavitation. It is not only suitable for more demanding working conditions, but also can customize various flow coefficients to meet the customers' more detailed process requirements. The control gas, liquid, steam and other media are widely used.
