Construction and Principle of Operation
The basic design of the Mancuna Vacuum Valve consists of two parts
only, a flanged steel funnel, and a flexible rubber sleeve.
The sleeve is held in a collapsed condition by the negative pressure
under which the dust collector operates.
The weight of the collected material above the valve builds up until
the head is sufficient to force it through the valve.
The seal is then automatically re-created. Each size can be supplied
with or without a steel housing incorporating a removable panel.
Normally the sleeve consists of Neoprene Rubber which is resistant to
most chemicals and will withstand temperatures up to 121°C (250°F).
higher temperatures the 8" and 10" sizes can be supplied with sleeves in
Silicone Rubber, 205°C maximum (400°F).
