The stations are intended for remote control of electric drives for machines and mechanisms in stationary plants and on ground, sea vehicles, where they
are driven manually by operator, as well as for signaling associated with the specified electric drives or other electrical devices.
The stations with 1ExdeIICT6 Gb , 2ExedIICТ6 explosion protection marking are intended for operation within explosion hazardous industrial areas, vehicles and storage facilities for products of chemical, oil-refining, gas and other branches of industry.
Enclosure of PVK stations with indication is made of premix and consists of body and cover. Inside the enclosure one or two (accordingly for one- or
two-button stations) contact blocks ensuring electric circuit switching are installed on the cover.
Drive of “Stop” button is mushroom with self-locking (or without self-locking by special order), “Start” drive is cylindrical without self-locking. The main actuator of the stations are contact blocks. Blocks have one normally open (1NO) and one normally closed (1NC) contacts. Terminal clamps of blocks allow connecting of two wires with cross section up to 2.5 mm2 each or one wire with cross section up to 4 mm2.
On default in stations PVK-15, 18 with indication one red “Stop” button with self-locking and one light indicator are installed, in stations PVK-25, 28 with indication one red “Stop” button with self-locking, one green “Start” button and one light indicator are installed. On default stations are equipped with cable glands VK12 (2 pcs.). The control stations can be equipped with one or two glands of other types having explosion protection marking corresponding to level and type of station explosion protection by the Customer’s request.
Weight of stations PVK-15, 18 with indication is 1.0 kg maximum, weight of PVK-25, 28 with indication is 1.4 kg maximum.
