ZZWPE Electric Temperature Regulating Valve

The ZZWPE-16C electric temperature regulating valve is suitable for controlling large caliber and heat transfer oil. The valve only requires a regular 220V power supply and utilizes the energy of the regulated medium to directly adjust and control the temperature of media such as steam, hot water, hot oil, and gas. It can also be used to prevent overheating or heat exchange situations.

summary

The ZZWPE-16C electric temperature regulating valve is suitable for controlling large caliber and heat transfer oil. The biggest feature of this valve is that it only requires a regular 220V power supply, and utilizes the energy of the regulated medium to directly adjust and control the temperature of steam, hot water, hot oil, and gas. It can also be used to prevent overheating or heat exchange situations. The valve has a simple structure, convenient operation, wide temperature adjustment range, fast response time, reliable sealing performance, and can be adjusted freely during operation. The ZZWPE-16C electric temperature control valve is widely used in hot water supply for departments such as chemical, petroleum, food, light textile, hotels, and restaurants.

2、 Structure and Principle

The regulating valve consists of three parts: the main valve, intelligent actuator, and sensor. According to user needs, there are two types of structures: heating type and cooling type.

Structure and principle of heating type regulating valve

Before working, the main valve core is in the half open position and the sensor is in a natural state. Connect the power supply and fully open the main valve core. The medium flows into the main valve body in the direction of the arrow and heats the heat storage box through the valve core. When the temperature rises to the corresponding set value, the sensor generates a corresponding linear signal to input into the integrated intelligent actuator, which then drives the valve stem and valve core to generate displacement, closes the main valve core, and stops heating. When the temperature drops below the set value, the sensor generates a linear signal input to the actuator, driving the valve core to gradually open, causing the medium to flow into the heat storage box according to parabolic characteristics, and heating until the set value is reached. In this way, the controlled medium is always controlled within the set temperature range, thus achieving the goal.

ZZWPE Self operated Electric Temperature Regulating Valve Debugging:

(1) Connect to a 220V AC power supply. Open the main valve and slowly open the shut-off valve in front of the valve.

(2) Connect the bulb wire to the terminal post.

(3) Observe whether the change in set temperature is within the allowable range. If it is found to be too high or too low, the drive casing can be removed and the temperature setting switch can be turned (fine adjustment is sufficient). Repeatedly adjust. Until the temperature is controlled within the allowable range.

(4) This valve should be used in places with an ambient temperature of -25~55 ℃, and attention should be paid to moisture prevention.
