Wall supply valves WI-150/SPK-150 and WI-390/SPK-390

Wall supply dampers WI - 150/SPK - 150 and WF - Z90/SPK - Z90 have an increased heat - insulating property due to the cellular structure of the body walls and the porch. The porch of the valve provides hermetic closing of the valve due to the frost - resistant rubber and pile sealant fixed along its perimeter.

Valves WI - 150 / SPK - 150 and WF - 390 / SPK - 390 - normally open, open due to a pushing spring and gravity acting on the porch. To close the valve, it is necessary to apply a force of no more than 1.5 kg - for WI - 1501SPK - 150 and no more than 2 kg - for WI - 390 / SPK - 390.

The curved shape of the porch makes it possible to effectively direct the air flow to the upper part of the house, which, in case of cage keeping of birds, makes it possible to exclude direct contact of cold supply air with the bird.

The WI - Z90 / SPK - 390 damper with high performance is especially effective in the southern regions of Russia and allows you to successfully implement economical minimum / transitional ventilation schemes with inflow through the side walls and exhaust through the fans on the end wall, without resorting to the installation of exhaust roof shafts.
