Piston type Siemens electric control valve

Piston type Siemens electric control valveThere are elastic elements inside the structure, such as springs, bellows, bellows type temperature packs, etc., which utilize the principle of balancing elastic force and feedback signals. The indirect acting regulating valve adds a pilot valve that amplifies the feedback signal and drives the main valve disc to change the valve opening through the actuator.

Performance characteristics:

(1) Proportional band, large integration time, freely adjustable range, suitable for different working conditions.

(2) The controller has powerful functions, mature software, and diverse functionalities.

(3) The actuator has strong force and runs smoothly.

(4) The actuator has a stroke verification function, which automatically identifies different valve bodies.

(5) The sensor has good pressure characteristics and high accuracy.

Piston type Siemens electric control valvePay attention to the following aspects when using:

1. Electric control valves are field instruments that require an ambient temperature range of -25 to 60 ℃ and a relative humidity of ≤ 95%. Waterproof and cooling measures should be taken when installing in outdoor or high-temperature environments. The source of the earthquake should be kept away from the source or additional anti vibration measures should be taken.

2. Regulating valves should generally be installed vertically, and in special cases, they can be tilted. If the tilt angle is too large and the valve itself weighs too much, supporting components should be added to protect the valve.

3. The installation of regulating valve pipelines should generally not be too high off the surface or plate. When the pipeline height is greater than 2m, a platform should be set up as much as possible to facilitate the operation of the handwheel and maintenance.

4. Before installing the electric control valve, the pipeline should be cleaned to remove dirt and welding slag. After installation, in order to ensure that impurities do not remain in the valve body, the valve should be cleaned again, that is, when introducing the medium, all valves should be opened to prevent impurities from getting stuck. After using the handwheel mechanism, it should be restored to its original neutral position.

5. To enable the production process to continue in case of malfunction or maintenance of the electric control valve, a bypass pipeline should be added to the control valve.
