Cage Guided Single Seated Electric Globe Control Valve

Cage Guided Single Seated Electric Globe Control Valve

Thesingle seated electric globe control valveis a pressure balance regulating valve. It adopts a cage sleeve guide and a single seat sealing structure. Thiselectric globe control valveis equipped with an electric actuator,and the flow passage is S-streamline and the quality seal ring is used.The cage guided single seated electric globe control valve has the characteristics of stable operation, large allowed differential pressure,accurate flow characteristics and low noise. It is especially suitable for work situations where the pressure difference between the upstream and the downstream is large.

The Features of Single Seated Electric Globe Control Valve:

1.单个座椅电球控制阀的可调节范围很大，可调节比率
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 ofsingle seated electric globe control valvecan directly control the opening of the valve by the current signal, without the need of a servo amplifier.
