Hydraulic Pressure Management/
Water Savings Valve with Dual Setpoints
Typical Performance
A dual system pressure with reduced system
pressure during low demand periods is illustrated in
the chart. At low flows, a minimum pressure is
maintained and as flow increases to the switch point,
delivery pressure increases to the maximum pressure
set point for switch. The point between low pressure
and high pressure setpoints is adjustable to fine-tune
the valve to system requirements. The “water saving
zone” below maximum pressure line represents valve
effectiveness in reducing water losses and frequency
of pipe breaks in a system.

MODEL
The Cla-Val Model 98-06/698-06 Water Saving Valve is
a pressure reducing valve that uses two downstream
set points to achieve optimum system pressure; i.e. the
capability delivering only the pressure that is needed to
meet current demand.
A high pressure set point is selected for high flow
demand and a low pressure set point is selected for low
demand. This dual set point arrangement allows for
reduction in water consumption as well as unintentional
water loss by keeping system piping from being over-
pressurized during periods of low demand. It does this
without inhibiting adequate pressure during high or fire
demand. The design is 100% hydraulic and, in addition,
to the dual pressure set points, the transition point at
which the pressure changes based on the flow is also
adjustable. The patented design of the valve allows for
smooth transition from one set point to the other,
providing optimum performance and measurable water
savings by reducing consumption, minimizing leaks and
lessening the potential for pipe breaks.

Many factors should be considered in sizing pressure reducing valves including inlet pressure, outlet pressure and flow rates.
For sizing questions or cavitation analysis, consult Cla-Val with system details. Not Recommended for Dead-end Service
