Page 13: Installation
ART 22 Installation Valves are precision manufactured products and should not be subjected to misuse. Careless handling, allowing foreign particles to enter the valve through the end ports, lack of cleaning both valve and system before operation should be avoided. Excessive force during pipe tightening and handwheel operation should be avoided. -
Page 14: Test Points
• The double regulating feature is now set which enables the valve to be fullyclosed for isolation and re-opened to the previously set position. It is recommended to record this set position for reference later if necessary. Maintenance The Albion Art 22 does not require any routine maintenance.
