Powers 410 Series Balancing Valves - Manual

Hot and cold water enter their respective ports and the flows
are equalized through the action of the balancing poppet (1).
The poppet caps (2) prevent a “slamming” of the poppet as it
approaches the seat by a feedback of the controlled pressure.
The entire balancing poppet assembly is contained in a Celcon
chamber (3). This chamber is replaceable as a complete
cartridge. After the hot and cold flows are equalized, they are
mixed by the action of the mixing plate (4). As the temperature
adjustment stem is rotated from shutoff to maximum hot water
temperature, the mixing plate passes the required proportion of
hot and cold water to produce the control point. With the
adjustment stem in its full clockwise position, shutoff is
obtained by shutting off both supplies.
The adjustable limit stop (5) allows the user to set the maxi-
mum discharge temperature. This mixer does not recognize
supply water temperature changes so any variation in the
water temperature will affect the control point and the
adjustable limit stop setting.
CAUTION: Maintenance of units requires resetting of
adjustable limit stop.

The Series 410 Hydroguard is particularly recommended
for showers and shower bath installations in motels, hotels,
dormitories, and high-rise apartment buildings.
Troubleshooting
What to look for if:
1. The flow of water is less than desired.
a. Valves upstream from supply not fully open.
b. Low supply pressures.
c. Accumulation of lime deposits in hot water pipes,
restricting the flow of hot water.
d. Showerhead clogged.
e. Low hot water supply temperature.
2. Flow of water is completely shut off.
a. Valves upstream from supply completely closed.
b. Failure of hot or cold water supply pressure. The
HydroGuard is constructed to restrict the flow of water
on hot or cold water supply failure.
3. Flow is untempered hot or cold water.
a. The water supplies are connected to the wrong ports.
See Fig. 5 for instructions on reversing the mixing
plate.
b. DIAPHRAGM is ruptured, replace with new cartridge.
4. Flow of water continues when HydroGuard is shut off.
a. Worn SHUTOFF DISCS. Replace worn disc.
b. Foreign particles on mixing plate.
c. Scored mixing plate.
5. Maximum temperature is too low.
a. Accumulation of lime deposits in hot water pipes,
which restricts the flow of hot water.
b. The Adjustable Limit Stop is not at its maximum
adjustment.
c. Hot water temperature too low.
