I VAL-MATIC'S ½"-3" AIR/VACUUM VALVE OPERATION, MAINTENANCE AND INSTALLATION NTRODUCTION The Air/Vacuum Valve has been designed with stainless steel trim to give years of trouble-free operation. This manual will provide you with the information to properly install and maintain the valve to ensure a long service life. The Air/Vacuum valve is designed to exhaust large quantities of air upon system start-up and allow air to re-enter the line upon system shut down.

DESCRIPTION OF OPERATION (Cont'd) The only moving parts in the valve are the float and the float guide. The float guide assures that the float enters the seat at the optimum angle and assures that the float will not make contact with any surface other than the resilient seat thus assuring long maintenance free life. INSTALLATION The installation of the valve is important for its proper operation. Valves must be installed at the system high points in the vertical position with the inlet down.
