The Features of ZDLP Electric Single Seat Globe Control Valve: 

ZDLP Electric Single Seat Globe Control Valve

1.The adjustable range of single seated electric globe control valve is large, the inherent adjustable ratio
is 50, and the flow characteristics can be linear and equal percentage.
2. The guiding area of the valve plug guide part is large, and this electric globe control valve has strong
anti-vibration performance.
3. The electric globe control valve has a compact structure and has a S streamlined passage, which makes the
pressure drop loss small and the flow rate large.
4. Electric actuators come in many forms and can be used for 4~20mA.DC or 0~10mA.DC.
5. The electronic type of single seated electric globe control valve can directly control the opening of the valve by the current signal, without the need of a servo amplifier.
