  • Page 3: Introduction

    INTRODUCTION Rectangular V370 and round RK 370 fire safety valves with fire resistance class EI 120 (ve i o) S are manufactured by FRAPOL Sp. z o.o. in Krakow and are intended for use in the construction industry as elements closing ventilation ducts during the fire within vertical fire barrier to prevent permeation of hot gases and fire smokes via this way to zones not covered by the fire.

    (or solder), which causes breaking of the glass cover (or dissolution of solder), and as a consequence the valve closes when the air flowing through the installation achieves the temperature of ~72°C. V370/HO RK370/HO The actuation of the heat-responsive device releases the peg of the mechanical thermal element based on it, and the latter, by moving backwards, triggers the element blocking the partition of the valve blocking it in the open position.

Opening of the valve occurs by turning the manual lever, during which the return spring is stretched.

    Valves in HO and HE versions By turning the manual lever (item 1 Fig. 1a or 2a) clockwise for V370 valves and anti-clockwise for RK370 valves, switch the cut-off partition of the valve from "closed" to "open" position, at the same time stretching the closing spring.

Air flow direction via the valve is of no significance for its assembly method (before or after the partition).
  • Page 9 32.5 mm This requirement means that valves of V370 or RK370 type should protrude from the wall on the drive side to the distance not greater than B=222.5 mm. 4.4.1.2. Connect the valves with the suspended ventilation ducts on both sides of the fire barrier.
  • Page 10 EI120 and thickness of 125 mm, the cut-off partition of the valve should remain in the axis of barrier thickness. Valves of V370 type must protrude from the wall on the drive side to the distance of 218 mm, while valves of RK370 type must protrude from the wall on the drive side to the distance of 213 mm.
