Limit switch VK type

Field of application

Limit switches of VK type are designed for remote control of stop pipeline valves in stationary installations, as well as for signalling the position of valves (closed or open) at power industry enterprises in alternating current circuits of 250 V frequency 50 and 60 Hz and DC voltage 220V.

The switches, depending on the circuit used, can provide:

1) automatic shutdown of the electric drive when the working member of the valves reaches the initial or final position;

2) electrical interlocking from simultaneous signal supply for valve opening or closing;

3) indication of reinforcement position by means of local indicator;

4) electrical connections according to the consumer diagram for:

- remote control of the electric drive from the control panel and stop the valves in any intermediate position using the "STOP" button;

- remote light signalling on the control panel of extreme positions of valves.

Сonditions of use

The switches are designed for operation in industries where the presence of explosive mixtures is excluded under operating conditions.

Type of climatic design of switches - У2, Т2, УХЛ2 as per GOST 10150-69.

Delivery type - for domestic market and export.

* - minimum number of revolutions of the drive from the closed position to the open position when turning 120 degrees
** - the maximum number of revolutions of the drive from the closed position to the open position when turning 270 degrees
