Description

Valve pneumatic device is used to shut off pipelines and control gas supply. The spindle, moving along the thread in the cover of the housing, transmits movement to the valve, which closes the inlet hole. Density of connection of cover with housing is provided by gasket, and spindle and cover - by gland device. The connection of the valve and the spindle is made with a gap that allows the valve cone to be centered along the cone of the closed hole, as well as to rotate freely relative to the spindle, which prevents wear of the working conical surfaces of the valve and the housing.
