Description

Electromagnetic valve of VN series DN 40 mm flanged with electromechanical gas flow regulator (positional control, LF230S actuator).

Switching frequency, 1 / hour, no more: 20.

Supply voltage: electromagnetic coil: 220 V, 110 V, 24 V (50 Hz); 24 V (DC);

electric drive of consumption: 220 V (50 Hz).

Climatic version: U3.1 ( - 30 . . . + 40 О С)

Valve protection class: IP65.

Protection class of the electric drive: IP54.

Full resource of inclusions, not less: 500,000.

Case material: aluminum alloys AK12OCh, AK12PCh.

Mounting position: any, except when the solenoid coil is located below the longitudinal axis of the valve.

Rotation angle of the regulator: 90 ° .

Regulator full stroke time, s: 150 (for a running engine); 20 (for a returnable spring).

The solenoid valve with positional control operates in the following modes:

  • "closed" (with de - energized electromagnetic coil);
  • "intermediate flow rate" - is 10 - 50% of the nominal (voltage is applied to the electromagnetic coil; the flow rate is set by rotating the regulating flap shaft when the clamp of the electric drive is loosened to the damper shaft);
  • "nominal flow" (voltage is applied to the electromagnet and the damper motor; the flow rate is set by changing the damper angle with the help of a mechanical stop on the electric drive).

When voltage is applied, the actuator turns the damper to the "nominal flow" position, limited by a mechanical stop, while simultaneously stretching the return spring. If the supply voltage is cut off, the spring returns the damper to the "intermediate flow" position.
