The DO7-ZF is a drop tight pressure reducing valve suitable for
water up to 70˚C (90˚C for short periods) and inlet pressures up
to 16 bar. The outlets pressure can be adjusted between 0.5 bar
and 3 bar. Typically these valves are used on the incoming water
supply pipe to a dwelling to reduce the pressure at the cold taps
and provide a more even pressure between hot and cold supply.
The D07-ZF is also suitable for unvented hot water storage
systems and when supplied for this purpose, are factory set and
sealed to prevent field adjustment. These valves are WRc
approved for use on potable water. Manufactured in
