1. With the Brine Measuring Tank full and the 122 Brine
Measuring Valve in the "Float Up" position, the valve
is ready to open when vacuum is applied. The Brine
Transfer Valve is positively held closed by pressure
thru tube #1.
2. When unit starts its brine operation, water passes
thrd the injector, creating vacuum in the brine line
to the 122 Valve.
3. With the control in the ’Float Up" position and
vacuum present, the 122 Valve opens to a11ow brine
to flow through the injector into the unit. Brine flows
thru the unit and out to waste.
4. As the brine is withdrawn from the Brine Measuring
Tank, the float travels down the float rod. Upon contacting
the lower stop, the pilot control is positioned
to apply positive pressure to the cover chamber of the
122 Valve. Pressure closes the valve and stops the
flow of brine to the unit.
5. When the flow of brine stops, only fresh water continues
to flow thru the injector to rinse the brine from
the unit.
6. The Brine Transfer Valve is held closed until the
brine line is repressurized after the brine rinse step.
7. At this time the pressure is directed thru tube #2 to
the power unit chamber of the 7100 PKI-IR transfer
valve causing it to open, permitting brine flow from
the salt storage tank to the brine measuring tank.
8. As the Brine Measuring Tank refills, the float travels
up the float rod. Upon contacting the upper stop, the
pilot control is positioned to close the Brine Transfer
Valve and hold positive pressure to the cover chamber
of the 122 Valve, maintaining it in its already closed
position.
9. Fresh water is admitted into the Salt Storage Tank by
the Bob Float Valve. The lowest level in the Salt
Storage Tank is automatically maintained above the
highest level in the Brine Measuring Tank.
The operation of the No. 122 Brine Measuring Valve and
the No. 7100 PKHR Brine Transfer Valve is described
under steps thru 7. Refill of the brine measuring
tank is then by pumping rather than gravity.
With the Brine Pump ’System the 7100 PKHR Brine
Transfer Valve is fitted with either a mechanical or pressure
switch to start and stop the brine pump. A mechanical
switch is activated by the vertical movement of the
diaphragm in the 7100 valve. A pressure switch is activated
by pressure tube No. 2.
When tube No. 2 is pressured, the 7!.00 valve opens,
the pump starts, and brine is pumped into the brine
measuring tank until the float bears against the upper stop
and positions the Pilot Control. This relieves pressure
in tube No. 2 and pressurizes tube No. to close the 7100
valve and stop the brine pump.
