VAL-MATIC’S 1/2”-3” WELL SERVICE AIR 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 Well Service Air Valve has been designed with stainless steel trim to give years of trouble free operation. The purpose of the valve is to automatically discharge and admit air into the discharge pipe of a vertical turbine or well pump. The Size, Maximum Working Pressure, and Model No.

INSTALLATION The installation of the valve is important for its proper operation. The valves must be installed in the vertical position with the inlet down on the discharge pipe between the pump and check valve, see Figure 2. During closure, some fluid discharge will occur so vent lines should extend to a safe location or open drain for in-plant installations. A shutoff valve should be installed below the valve in the event servicing is required.
PAGE 4
THROTTLING DEVICE CONSTRUCTION The Throttling Device has an exhaust disc which is typically adjusted between 5% and 30% open to control the venting rate. The valve needs to be set in the field and tuned to the operation of the pump. The Throttling Device should be opened just enough so that all of the air is discharged before the check valve opens. Opening the throttling device further will increase the pressure surge in the pump column.

DISSASSEMBLY MAINTENANCE The Well Service Air Valve requires scheduled lubrication or maintenance. no The valve can be disassembled without removing it from the pipeline. Or for convenience, the valve can be removed from the line. All work on the valve should be performed by a skilled mechanic with proper tools. Refer to Figure 2. All work on the valve should be performed by a skilled mechanic with proper tools. Refer to Figure 2. INSPECTION: Periodic inspection for leakage can be performed.
