VAL-MATIC’S 4”-20” AIR/VACUUM VALVE OPERATION, MAINTENANCE AND INSTALLATION INTRODUCTION 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 has been designed with stainless steel trim to give years of trouble free operation. The Air/vacuum valve is typically mounted on a pipeline at the high points or large changes in grade.

INSTALLATION Valve Size (in) 4 6 8 10 12 14 16 18 20 The installation of the valve is important for its proper operation. The valves must be installed at the system high points in the vertical position with the inlet down. For pipeline service, a vault with freeze protection, adequate screened venting, and drainage should be provided. During closure, some fluid discharge will occur so vent lines should extend to an open drain for in-plant installations.

The general details of construction are illustrated in Figure 5. The body (1) is flanged for connection to the pipeline. See page 2 for installation to the pipeline. WARNING: The valve must be drained before removing the cover or pressure may be released causing injury. 1. Close main isolation valve.
