Double-Action Fire Safety Valve SigmaVent-15-DD-SV for Effective Fire Protection

The valve is manufactured as standard, channel version with rectangular body and external actuator. The body is made of galvanised steel and is structurally similar to a 320 mm long section of duct, with connecting flanges made in one piece with the body. The box-type damper is made of galvanised steel and is packed inside with fire-resistant flame retardant material. A special feature of the Sigmavent-15-DD damper is the location of the actuator in a fireproof box to protect it from an open source of fire and maintain its operability. The valves are operable in any spatial orientation.
