Suction Manifold Valve

Why do I need a manifold valve anyway?

The problem: 
Two or more dental surgeries (operatories) sharing the same vacuum pump.
When one chairside suction is being used,  you want the remaining chairside suction to remain quiet but also ready for use. 

What most manufacturers do:
A hand operated valve is placed near the suction tip. Unfortunately these valves are prone to jamming as fine particles of detritus find their way into the mechanism. 

The XeroStar solution

An electrically switched air valve  -   The new XeroStar Manifold Valve !
Actually it's two or more valves joined to a common vacuum manifold - see the snapshots below

The Benefits

• This eliminates the need for any form of chairside flow control such as hand operated valves - which tend to be noisy and cause problems as they become clogged with detritus.  They are also costly to replace.

• No hissing or gurgling noises - just a pleasing, instantaneous shut off  (or instantaneous switch on!)

• fully automatic - no need for fumbling with valves or switches.

Each surgery has it's own remote controlled (low voltage electrical) valve situated in the plant room near the separator.
Important Note: Individual manifold valves can be located near the chairside if required, depending on existing pipelines. 
It's a fairly flexible concept!

Each surgery has access to the same vacuum pump/separator via it's own manifold valve.

The valve is designed to shut off the vacuum instantly when the handpiece is replaced in the cradle even if the vacuum motor is still running.  This eliminates any "noise fall off" or gurgling sounds. The result is a pleasing, instantaneous shut off.  ie The suction noise stops immediately the handpiece is replaced.

The vacuum will resume instantly when the handpiece is lifted.

Each surgery can "tap into" this vacuum as required.  There is no need for the second surgery to manually "turn off" their suction while surgery number one is operating - it all works automatically!

Only when all handpieces are replaced does the vacuum motor switch off.

The number of surgeries operating with suction at any one time is only limited by the capacity of the vacuum motor. 
The capacity of the vacuum motor can be matched closely to the number of surgeries.

When the maximum number of surgeries are operating, an extra vacuum motor can be automatically switched on to augment the vacuum for short periods. This negates the need for one large (expensive) motor to be in continuous service and wasting power over long periods. Therefore only when all operatories are simultaneously using suction  over extended periods is one large motor justified. 

The Vacuum Manifold comes complete with the required number of valves, together with power supply and control relays. 

See snapshot above showing three operatories connected to one manifold.
