ZZWPEIntroduction to Electric Temperature Control Valve Products

The electric temperature control valve adopts an integrated design, which can automatically adjust and effectively control the temperature of steam, hot water, hot oil and other media. The valve has a simple structure, easy operation, wide temperature control range, fast response time, reliable sealing performance, and can be adjusted freely during operation. Therefore, it is widely used in hot water supply in chemical, petroleum, food, textile, hotel and restaurant departments.

ZZWPEFunctions of electric temperature control valve products

Automatic adjustment function:

As long as the user sets the temperature, the actuator can automatically adjust the opening size of the valve based on the actual measured temperature.

Self diagnosis and diagnosis ability:

When the thermocouple breaks during the control process, it has the ability to select the output protection mode of the actuator (i.e. the actuator is in the fully open position, fully closed position, hold position, and set position)0-100%）

There is a manual adjustment function
