Proportional control angle seat valve

  • Working principle

    The valve positioner receives a 4-20 mA current signal from the controller or control system, converts it into a gas signal through the processor, controls the valve opening, and cooperates with the valve adjustment cone to achieve fast and accurate flow regulation of the valve.

  • Characteristics

    1. Easy to adjust and easy to operate;

    2. Stable operation;

    3. The unique adjustment cone design establishes the linear or proportional relationship between the valve opening and closing stroke and the flow rate, thus achieving accurate and fast flow adjustment.
