General Application

These Pressure Balance Valves are for use with GrohFlexTM
universal rough-in valve.

Planing of piping is done at the time of the rough installation.
2 different types of PBVs are possible.
Observe the possible combinations, see Page 1.

Specification

• Concealed single handle pressure balancing valve for tub
and shower

• Integral service stops

• Integral check valves prevent cross flow

• Pressure balanced diaphragm cartridge automatically
adjusts to inlet pressure fluctuations

• Cartridge restricts hot water supply if the cold pressure fails,
to prevent scalding

• Flow pressure:

- min 1 bar or 14.5 psi

- recommended 1-5 bar or 14.5 – 72.5 psi

If greater than 5 bar or 72.5 psi, fit pressure reducing valve

• Max. operating pressure 8.5 bar or 125 psi

• Max. test pressure 34.5 bar or 500 psi

• Flow rates at 3 bar or 45 psi

- Type #1 19 843 23 l/min or 6,1 gpm

- Type #2 19 844
bottom outlet 20 l/min or 5,3 gpm
top outlet 11 l/min or 2,9 gpm

• Temperature

- max. (hot water inlet) 80 °C or 180 °F

- The handle rotation stop may be used to limit the maximum
temperature. The maximum temperature will be reached
when the handle is turned in a counter-clockwise direction.

• Back-to-back installation is possible by reversing the
pressure balancing cartridge.

• Water connection: cold - RH

hot - LH

General preparation

1.Cut of the excess blue box material, see fig. [1].

2.Seal the rough-in valve, see fig. [2].

3.Close the integrated service stops, see fig. [3].

4.Remove flush cap, see fig. [4].

Installation Type #1 19 843

If both rough-in outlets are used, you have to install a spout
with diverter. If only the lower rough-in outlet is used, you

have to install a spout without diverter.

1.Install control unit and secure with screws, see Fig. [5].

2.Close valve by turning the adaper (A) clockwise until it
stops, see Fig. [6].

3.Open the hot and cold integrated service stops.

4.For installation of handle parts, see Fig. [7].

5.While installation observe the right mounting position.

If the pressure balancing valve is installed too deep, the
fitting depth can be increased by 25mm or 1" with an extension
set, Part No. 47 823, see page II.

Note:

The preset maximum temperature will change if the inlet
temperatures change or the setting of the water heater
thermostat is altered or if the water inlet temperature is
fluctuating.

Operation

Turn lever anti-clockwise:

- Open from cold to hot water flow, see Fig. [8].
The adjustable hot water limit stop (B) is factory set at a
position to limit maximum outlet temperature to below the hot
water supply temperature, see Fig. [7]. For installations where
there is need to modify the limit temperature, remove the limit
stop (B) and replace in a more clockwise position for colder
water, or more counter-clockwise position for hotter water.

Observe the mounting position of stop (C).
