Product features

The electric cage type regulating valve is a pressure balance type regulating valve. The sleeve guided pilot valve core is used inside the valve body. The valve core is provided with 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 is not suitable for particles and dirty media. It is the most widely used type of control valve.
Structure of electric cage type regulating valve
Features of electric cage control valve:
 
There are windows on the electric cage control valve to determine the flow and flow characteristics. The unique symmetrical porous cage valve flap can more effectively control noise and cavitation. It is not only suitable for more demanding working conditions, but also can tailor various flow coefficients to meet customers' more detailed process requirements. It is widely used to control gases, liquids, steam and other media.
