MODEL KPFS LIQUID LEVEL FLOAT SWITCH
VALVE REPLACEMENT KIT INSTRUCTIONS
RK-VALVE-KPFS VALVE REPLACEMENT KIT
The RK-VALVE-KPFS is the Valve replacement kit for the Kenco pneumatic float switch model KPFS. The Valve is made up of
three main components. These components can be seen in the middle view of Figure 1 and consist of the Valve Base, Valve Body
and Valve Cap. There are two screws that hold the KPFS to the Switch Body. These two screws also serve as the screws that hold
the valve assembly together. Because of this, each of the three Valve components are assembled to the Switch Body one at a time
until all three components are in place, then the two screws are installed to clamp the Valve assembly together and secure it to the
Switch Body. To get started with the assembly, the old Valve must first be removed.
Figure 1
Refer to the illustrations in Figure 1 for the Valve removal process.
To remove the old Valve:
1.
Turn off the supply line pressure to the Valve if system is pressurized.
2. Disconnect the supply and outlet lines. Disconnect the exhaust line if equipped.
3. Remove the Switch Enclosure Cover.
4. Remove the two screws holding the Valve assembly in place and discard.
5. Remove the Valve Cap, Valve Body, Valve Base, all of the O-rings and discard.
6. The Needle will be loose and probably laying inside the Switch Enclosure. Locate the Needle and discard.
7. Make sure the valve mounting surface on the Switch Body is clean and free of any dirt or debris. The KPFS
is now ready to have the new Valve installed.
