The Original Dome Valve

The operating efficiency of all Clyde Pneumatic Conveying systems relies upon our unique Dome Valve, currently installed in over 100,000 applications worldwide.

"Often imitated, never duplicated".

The pressure tight air operated bulk materials handling valve is simple in design and construction resulting in extremely sustainable process reliability even in the most difficult applications.

Key features:

Inflatable Sealing Mechanism The fast closing bulk material cut-off Dome Valve incorporates a unique pressure tight sealing arrangement. This is achieved by using an inflatable seal, which is automatically inflated on closure of the valve and deflated upon opening

Nominal Bores ranging from 50 - 400mm as standard

Temperature Range -20 to 450 deg C

High Availability over 3,000,000 cycles between major overhauls and 1,000,000 cycles for seal replacement
