Top Range
The TOP range of pressure reducers offers the same
high standards of design, construction and performance
as the ECO range but with extra features.
Emmeti have developed a membrane pressure reducer
with a balanced diaphragm construction. This design
ensures a high stability of outlet pressures, regardless of
variations in the upstream pressure.
The diaphragm is made of a synthetic material with a low
friction coefcient, reducing the formation of limescale
buildup, which is a main cause of installation failure.
The valve mechanism is ‘drop tight’ in compliance
with EN1567. This means that water pressure on the
downstream side of the valve will not creep up, even
when water is not owing through the valve.
The single-piece diaphragm assembly allows easy
servicing and replacement, without the need to remove
the whole body.
Additionally, the TOP range incorporates a serviceable
stainless steel lter designed to prevent contamination
of the pressure gauge and downstream pipework. Cold
water models have a transparent plastic cover so that
build up of sediment can be seen. Hot water models
have a brass lter cover
The TOP range also offers simple, accurate pre-calibrated
dial-up adjustment enabling the required pressure to be
preset prior to installation
The TOP range has a choice of two body styles, one for
compression sealing in DN15 and DN20 sizes and one for
at faced union sealing in 3/4”,1” and new 11/4” sizes
featuring internal and external BSP threads for reduced
stockholding.
These two together with a wide range of connectors
offers comprehensive connection options from 15mm
right up to 11/4”M.
Gauge ports are included on both sides, 1/4” BSP
female, for reading the downstream set pressure.
Technical Data
Maximum inlet pressure: 16 bar
Adjustable outlet pressure range: 1.0 – 6.0 bar
Outlet pressure: factory set to 3.0 bar
Factory Calibration:
In line test bench using 8.0 bar upstream pressure

and 3.0 bar downstream, 100% tested.
Adjustment:
Simply adjust turning the black control knob and

reading the displayed scale. You can calibrate to the

required downstream pressure before installing.
When ow begins it will control immediately to set

pressure.
