Heat transfer oil proportional electric control valve control principle

The intelligent electric temperature control valve accepts the DC current signal from the PID intelligent regulation instrument to change the flow of the regulated medium so that the controlled process parameters are maintained at the given value. Widely used in electric power, metallurgy, chemical, petroleum, textile, pharmaceutical, paper and other industrial production automation control.

Intelligent electric temperature control valve nominal diameter from 20 to 200mm, nominal pressure 1.0, 1.6, 4.0, 6.4MPa, the use of temperature range -40 °C ~ 450 °C, accept the signal 1 ~ 5V.DC or 4 ~ 20mA.DC . Among them, the intelligent electric single-seat temperature control valve is suitable for applications where the differential pressure is small, the viscosity of the medium is large, or there is a slight amount of particulate impurities. Intelligent electric sleeve temperature control valve is suitable for pressure difference occasions. According to the material of the valve inner sealing part, there are two types of metal-metal and non-metal-metal sealing, and when the latter valve is closed, the leakage amount can reach VI level (zero leakage) standard. According to different fillers, it can be divided into two types: general packing seal and bellows seal. The former is used in general situations, while the latter is used in important occasions where no leakage is allowed. Flow characteristics are linear or equal percentages.

Smart Electric Temperature Control Valve Ordering Information:

1. When the user has determined the valve type and model (especially non-standard models), the user should correctly explain the meaning and requirements of the model.

2. The user should order according to the product model listed in the sample. If there are special requirements for the product project, please state in the order:

1) Structure length 2) Flange standard 3) Structure of the valve: If the passage is full-diameter or reduced-diameter, body cover connection 4) Valve internals and other requirements for materials 5) Pressure test, inspection standards, marking and other requirements;

3, when the valve is used in a very important situation or the environment is more complex, please try to provide design drawings and detailed parameters, SENMI valve technology department for your review.

4. SENMI valve can be configured according to the specific requirements of the user electric device, pneumatic drive device, turbine device.

5. All kinds of valves produced by SENMI valve factory can meet the requirements of the order, and the products are strictly tested and tested according to the relevant standards one by one before leaving the factory.

6. The warranty period for all products of SENMI valves is: Customers are officially installed and used within 12 months.
