SV

Description


SV is a circular supply valve used to introduce air.
The valve is a practical ventilation solution, used in installations with constant or variable air flow.
Recommended for small rooms with wall or ceiling mounting.

The SV is equipped with an adjustable center disc and a mounting frame.
Screwing/unscrewing the center disc increases/decreases the space between the disc and the frame, thus obtaining the adjustment of the air flow.

Adjusting the disc is easy and is done manually.
The mounting frame is provided with holes and is used to attach the valve to the wall or ceiling.
The valve is provided with a sealing gasket.
