| Type Comments | The Zurn Wilkins Model ZW209BP Pilot Operated Pressure
Reducing Valve with Low Flow By-pass is designed for many
applications where the reduction of high inlet pressures to
safe and stable outlet pressure is required. The pilot assembly
reacts to changes in downstream pressure allowing
the main valve to modulate between the open and closed
position ensuring a constant downstream set pressure. Once
the downstream pressure reaches the pilot setting, the main
valve will seal shut. When the main valve closes, the low flow
bypass is set to a slightly higher pressure which allows it to
handle very low flows up to 10 GPM when there is off peak
demand. (An additional bypass may be needed to handle
flows between the bypass and main valve minimum flow.) In
addition the Model ZW209BP comes standard with epoxy
coating internally and externally for corrosion protection as
well as isolation valves and pressure gauges for quick and
easy maintenance or repair. |

| Application | The Zurn Wilkins Model ZW209BP Pilot Operated Pressure
Reducing Valve with Low Flow By-pass is designed for many
applications where the reduction of high inlet pressures to
safe and stable outlet pressure is required. The pilot assembly
reacts to changes in downstream pressure allowing
the main valve to modulate between the open and closed
position ensuring a constant downstream set pressure. Once
the downstream pressure reaches the pilot setting, the main
valve will seal shut. When the main valve closes, the Model
NR3 low flow by-pass remains open allowing low water flow.
The by-pass prevents downstream pressure to rise above its
set-point as flow decreases, protecting downstream components
from damage. In addition the Model ZW209BP comes
standard with epoxy coating internally and externally for
corrosion protection as well as isolation valves and pressure
gauges for quick and easy maintenance or repair. |
