VAL-MATIC'S AIR RELEASE VALVE (Simple Lever Type) 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 Release Valve has been designed with stainless steel trim to give years of trouble-free operation. The Air Release Valve is typically mounted at the high points in a piping system to automatically remove pockets of air as they accumulate.
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. 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 area in plant service. A shut-off valve should be installed below the valve in the event servicing is required.
3. Remove the 2 retainer rings (13) and pivot pin (12) that pass through the lever frame (3). The float (5) and float arm (10) will be free from the cover. Disconnect float from float arm (10). MAINTENANCE The Air Release Valve requires no scheduled lubrication or maintenance. INSPECTION: Check outlet for water leakage. If continuous water leakage occurs, valve inspection and repair is needed. 4. To remove lever frame (3), remove hex-head locator (21). Rotate seat (4) counterclockwise to remove. Table 2.
