Valve delay the fire

Delays the fire valve fire cast-1 (the valve) is intended to prevent the penetration of fire, smoke and combustion products in the fire in the premises, including pipelines, systems of General ventilation, air conditioning and heating, as well as for protection of openings in fire barriers in the residential, public, administrative-household and industrial premises.

Delays the fire valve with normally open damper (BUT) is designed to block the spread of fire (of fire and combustion products) at the air ducts and channels of systems of ventilation and air-conditioning systems and for the protection of openings in the enclosing constructions in the event of fire in buildings and constructions of different values. Valve damper is installed in the location or in the places of passage of the systems through fire breaks with controlled the limit of fire (fire-prevention walls, partitions and ceilings).

Delays the fire valve normally closed damper (NC) is installed in the supply and exhaust systems of emergency anti-smoke ventilation.

Delays the fire of the valve is to be installed in the premises of the categories, A and B on взрывопожароопасности and places sucking explosive and fire hazardous and corrosive environments.

delays the valve is made of steel ST3, followed by painting or, at the request of the customer, from the galvanized steel or stainless steel.

The valve is manufactured in a sound and can be installed in vertical and horizontal openings.

The valve can operate in any spatial orientation.

Delays the fire valve is produced according to the technical requirements TU 4854-001-72720007-08.

Type of climatic performance of valves – U3 type according to GOST 15150-69.

The characteristics of the external environment for operating and storage of the valve:

  • aggressiveness in relation to carbon steel of ordinary quality above aggression of air with temperature up to 80 C, a dust content is not more than 100 mg/m2;
  • with a temperature of -30 degrees C and up to +40 C;
  • with relative humidity up to 80%;
  • not containing explosives, an explosive dust, sticky and fibrous materials.

Delays the fire valve can be equipped with a terminal block. Connecting the wires to the terminal block is performed by the customer at his discretion.

The valve is equipped with the following drives:

  • Electromechanical with spring return;
  • electromagnetic with the thermal lock;
  • spring with the heat of the castle.

For Delays the fire valves with electromagnetic drive will need to include the disruption of power magnet after 15 seconds after the shutter.

On request of the customer, the valves can be equipped with electric drives of domestic and import manufacture.

Information on the drives available on request. To do this, you can contact us in any convenient way for you, see our contact details are available in section Contacts
