A range of top dial pressure reducers, available between ½” and 1”. Pipe union connectors are also available. Adjustable from 1 to 6 bar outlet pressure with top dial-up setting and include a built-in serviceable stainless steel filter and a gauge port (blanked off) either side. All Top range pressure reducers are WRAS approved.
The Top range of pressure reducers offers the same high standards of design, construction and performance as the ECO range but with extra features.
The diaphragm is made of a synthetic material with a low friction coefficient, reducing the formation of limescale build up, 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 flowing 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 filter 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 filter cover.
The TOP range also offers simple, accurate pre-calibrated dial-up adjustment enabling the required pressure to be preset prior to installation.
Gauge ports are included on both sides, 1/4” BSP female, for reading the downstream set pressure.
- Maximum inlet pressure: 16 bar
- Adjustable outlet pressure range: 1.0 – 6.0 bar
