Valve Maintenance Schedule
The two solenoid driven air valves used in Xandex pneumatic controllers to drive the Pneumatic Shuttle and Ink Cartridge are identical. Valve one (V1) supplies air to the ink cartridge, and is also referred to as the Cartridge Valve. Valve two (V2) supplies air to the pneumatic shuttle and is also called the Shuttle Valve.
Xandex Motorized Z controllers contain a third valve (V3) that is identical to the Shuttle and Cartridge valves. The Motorized Z uses this valve to change the air pressure supplied to the cartridge valve when inking in small dot mode. In normal operation, the third valve (V3) in the Motorized Z controller will not need replacement for the life of the unit.
Preventive maintenance for Xandex pneumatic controllers requires replacement of just the Cartridge Valve, or replacement of both the Cartridge and Shuttle valves at the intervals specified in the table below.
|Controller Model #||Replace||Interval|
|All Models||Cartridge Valve||
Continuous High Speed Use = 6 months
All other applications = Every 12 million cycles
|All Models||Cartridge Valve, Shuttle Valve and internal tubing as required||Every 24 months|
Two types of valve replacement sets are available from Xandex to facilitate controller preventive maintenance.
