Updated 247/447 Pump: Valve Plug Change
Change Notice
DV Systems has recently made a change to the design of the Valve Cap used on the ‘247’ and ‘447’ compressor pumps on our ‘Heavy Duty Industrial’ pressure-lubricated air compressors.
The new design has been implemented in September, 2018 and can be used on existing pumps in the field where a plug is damaged and needs replacing.
Valve Plug Replacement Tool
Installation of the valve plug requires the valve plug tool (part # VT1). Using the valve plug tool:
- Install the new Set Screw into the Valve Plug and torque to 15 ft lbs / 20.3 Nm.
- Install the Cap Nut (‘SS-7424’) onto the Set Screw and torque to 15 ft lbs / 20.3 Nm
- Install the new Valve Plug and torque to 125 ft lbs / 169 Nm
The new assembly (shown above) includes a new valve plug (part # 445-89-1) and set screw (part # SS-6043).
