Product Details

1Micro electric regulating valveProduct Overview:

1. Introduction:

Siemens electric temperature control valve is a special application of electric regulating valve in the field of temperature control; The Siemens electric temperature control valve consists of a German SIEMENS original controller, actuator, sensor, and flow control valve.

2、 Application areas:

1. Heating system heat exchanger or heat exchange unit;

2. Domestic hot water system;

3. Air conditioning water/air system;

4. Thermal temperature control for production processes.

3、 Siemens temperature control valve (SKC62) product advantages:

1. Different on-site operating conditions can flexibly adjust control parameters to make the system more efficient;

2. By using calculus calculations, predict temperature trends in advance and achieve accurate temperature control;

3. The controller can read the current temperature value and observe the working status of the valve;

4. Scalable functions, such as temperature compensation, remote settings, day night and winter summer conversion, cascade control, over temperature alarm, remote communication, central monitoring, etc., energy-saving and safe;

5. Users can choose the circuit breaker protection function according to their requirements, and the valve will automatically close when there is a power outage;

6. Realize various intelligent energy-saving operation modes, unmanned operation, and high cost-effectiveness.

4Micro electric regulating valveCommon knowledge of selection:

1. The selection of valve materials, flow capacity, and actuator shut-off force should be comprehensively considered based on the type of heat medium (steam/hot water), temperature, pressure parameters, and operating conditions (heat exchanger type, on/off system);

2. When used for steam flow control, it generally refers to saturated steam with 98% dryness. If it is superheated steam, due to changes in the adiabatic index k of the steam and corresponding changes in the fluid viscosity coefficient, the flow rate generally needs to be recalculated and verified;

3. The flow rate of the medium is proportional to the square root of the pressure difference before and after the valve. Excessive pressure difference not only generates noise, but also causes cavitation on the valve body, affecting its service life. Mild cases may result in poor sealing, while severe cases may cause explosions and result in major accidents such as casualties;

4. The temperature regulation curve is the guarantee for achieving temperature control effect. Except for special requirements for fast heating systems, valves should be ensured to have equal percentage or parabolic characteristics as much as possible;

Equal percentage: Q/Qmax=R (L/Lmax-1)

Parabolic shape: Q/Qmax=1/[1+(root R-1) L/Lmax] 2

5. Electric temperature control valves cannot be used as shut-off valves for a long time. When shutting down, please turn it off;

6. Two way valves cannot be used as three-way valves by removing the blind plate from the valve base;

7. When using third-party produced equipment to match Siemens products, attention should be paid to meeting safety requirements;

8. The temperature control valve cannot be used in a direct water supply system and requires circulation. If it is an instant heat exchanger, a heat storage tank needs to be added.
