Company "Vector" represents valves fire GUARD, ROOM (frost-proof valve) and KID (pressure relief valve). Fire valves Vent-Vector is designed to block the spread of fire and combustible materials through vents. The fire resistance of fire dampers GUARDIAN from 1 to 1.5 hours.
KOM valves are frost-resistant, equipped with a controllable actuator that provides an initial opening of the valve when it is freezing. Further opening of the valve occurs automatically when you turn on the fan. Close the valve when you disconnect the fan and return the actuator to its original position is provided by the reverse spring the actuator and gravity.
Valves KID overpressure is established in the enclosure of the tambour-sluices or Elevator shafts, which directly adjoin the protected areas. Door tambour-gateways should be interlocked with the actuators in the loop the opposite direction. Instead of two ordinary valves with actuators (normally-closed and valve with adjustable louver grills) possible to install the excess pressure valve to simplify installation work.
