High Conductance (HC) XL High Vacuum Ball Valve

HC Ball Valve


A&N’s High Conductance ball valve is the latest and largest addition to the Extended Life (XL) ball valve series. Including the XL’s patented fully-stabilized stem design, the HC provides maximum conductance with its fully ported ball and shortened two-piece corrosive resistant 316L stainless steel body.

The smooth profile makes this design easier and more efficient to heat. The valve is opened and closed manually or pneumatically by 1/4 turn, quick actuation. During actuation, the PTFE Teflon® seats wipe across the ball. This feature reduces particulate build-up, making this valve robust in particle-rich effluent streams.

New HC Features

Two-piece body

One less body o-ring seal means one less potential leak path & huge maintenance cost reductions when using perfluorelastomers

Smooth profile

Maximizes heat transfer from heating components

Minimized overall length and slimmer profile

Increases conductance and reduces weight & footprint

Fully bored ball port

Maximizes conductance with straight-through, unimpeded flow

Extra space between body & handle brackets

Minimum of 5/8" clearance allows more room for heating components

Adjustable stroke actuator

Adjusts +/-5° to ensure proper open/close over life of the valve

Integrated handle lock

Prevents accidental opening/closing. Lock Out-Tag Out ready
