Product Description

Electric Control Valve

Our Self-forced temperature control valve needs foreign energy –AC 220V. It is using itself energy of controlled medium to automatically control the temperature.

Nominal Pressure: PN1.6, PN4.0, PN6.4

Set temperature range: 0~270°C

Connecting join with Temperature Controller: G1 Male screw

Flange standard: PN16, conforming to JB/T79.1,PN4.0,PN6.4,comforming to JB/T79.2 convex flange.

Face to face dimension: conforming to GB12221-89.

Self-forced temperature control valve has a complete range of structure —ZZWP/ZZWM

Single seat/Sleeve Control Valve.

There are two model —Heating adjustment (B type) and Cooling adjustment (K type).

The features are wide range of set temperature and easy to adjust. With over-temperature and overload protection, it is safe and reliable. It is easy to set temperature indicated by temperature scale. During working, it could be set continuously
