VAL-MATICS WASTEWATER 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 Wastewater Air/Vacuum Valve has been designed with stainless steel trim to give years of trouble free operation. Regular maintenance may be required for valves subject to fluids containing high suspended solids with greases/oils.

INSTALLATION 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. A shutoff valve should be installed below the valve to allow regular maintenance.

6. Slowly open valve A to place unit back in service. MAINTENANCE The Wastewater Air/Vacuum Valve should be scheduled for inspection and backwash on a regular basis. The use of Fusion Bonded Epoxy (FBE) interior coating greatly minimizes the need for backwashing. Based on experience in service, a more frequent backwash regimen may be desirable to minimize leakage. WARNING: Wear safety glasses to look into the valve outlet after installation. Released fluid can cause injury.

TROUBLESHOOTING REASSEMBLY Several problems and solutions are presented below to assist you in troubleshooting the valve assembly in an efficient manner. All parts must be cleaned and gasket surfaces should be cleaned with a stiff wire brush in the direction of the serrations or machine marks. Worn parts, gaskets and seals should be replaced during reassembly. Refer to Figures 2 and 3. 1. Leakage at Bottom Connection: Tighten valve threaded connection.
