Electric steam temperature control regulating valve

1、 Product Introduction:

The electric steam temperature regulating valve is composed of a 381L electric actuator and a straight stroke regulating valve body. It is a high-performance regulating valve that can be widely used in automatic control systems in industries such as power, metallurgy, petroleum, chemical, pharmaceutical, boiler, and light industry.

ZZWPE-16PElectric steam temperature control regulating valveThe electric actuator receives control signals such as 4~20mA/4~12mA/12~20mA/0~5V~1~5V, changes the opening of the valve, and feeds back the isolation signal of the valve opening to the control system to adjust parameters such as pressure, temperature, flow rate, and liquid level.

ZZWPE-16PElectric steam temperature control regulating valveThe series adopts top guide and single seat sealing mechanism. Compared with other similar regulating valves, it has outstanding advantages such as simple structure, large rated flow coefficient, and small valve seat leakage. In addition, the series with soft sealing structure has both regulating and cutting functions, making it a type of regulating valve that can also be used as a cutting valve.

2、 Product advantages:

1Automatic adjustment: It can automatically adjust the valve opening according to the set temperature, maintain temperature stability, and reduce manual intervention.Equipped with 381L straight stroke electric actuator, it has small size, full specifications, light weight, high thrust, easy operation, no adjustable potentiometer, high reliability, and low noise.

2Energy saving and efficient: By precisely controlling the flow rate of the medium, energy waste is avoided and system efficiency is improved.The 381L electric actuator adopts an integrated structural design with self diagnostic function, making it very convenient to use and calibrate.

3Quick response: The valve can be quickly adjusted when the temperature changes, ensuring timely temperature control.There is a digital display window where control signal values and valve position values can be seen.

4Easy to install: The structure is simple, and installation and maintenance are convenient.

5. High reliability: Using durable materials and technology to ensure long-term stable operation.381L electric actuator function: with fault diagnosis, alarm and protection functions for broken control signals. When the signal is interrupted, the actuator can be turned on or off; Or close; Or maintain; Or any predetermined position between 0 and 100%. Equipped with valve blockage fault diagnosis, alarm and protection functions.

6. Strong adaptability: Suitable for different media and temperature ranges, widely used in heating, air conditioning, industrial and other fields.

7. Remote control: Some models support remote monitoring and adjustment, improving management convenience.

8. Good safety: equipped with overload protection and fault alarm functions to ensure system safety.
