BRANCH<br />
DEVELOPMENT<br />
Branch location is imperative<br />
for good business, not just<br />
for us but for you too. Take a<br />
look at the latest changes to<br />
the <strong>Tradelink</strong> network to help<br />
make life easier for you.<br />
Unfortunately earlier this year<br />
we had to close our branch in<br />
Margaret River WA, with the<br />
Busselton store looking after<br />
customers and doing deliveries<br />
in the area.<br />
Last month we also said<br />
goodbye to the branch at West<br />
Gosford in NSW with the team<br />
at the Erina store looking after<br />
customers and doing deliveries<br />
in the area.<br />

OVENTROP HYDROMAT DP –<br />
DIFFERENTIAL PRESSURE REGULATOR<br />
Available in both fl anged and BSP<br />
threaded versions, using the Oventrop<br />
Hydromat DP will lead to a longer life<br />
for system parts and increased system<br />
effi ciencies, producing energy savings<br />
and lower end-user costs.<br />
Oventrop’s differential pressure regulators,<br />
Hydromat DP, are proportional regulators designed<br />
to work without auxiliary energy to ensure constant<br />
differential pressure within a necessary proportional<br />
band across a system.<br />
As the differential pressure in the installation<br />
increases, the valve disc closes down and then<br />
re-opens as the pressure falls. The regulator<br />
reduces the excess differential pressure until the<br />
set pressure in the pipe is reached.<br />
When used in conjunction with a manual balancing<br />
valve such as the Oventrop Hydrocontrol R or F,<br />
it will keep constant design fl ow at heating and<br />
cooling units.<br />
End user energy savings and reduced contractor<br />
hardware costs are achieved by installing the valve<br />
in the return line and connecting it via a capillary<br />
tube to the supply line.<br />
This suffi ciently services multiple units at once<br />
to minimise overfl ows, meaning valves are not<br />
required to be installed at each terminal. Instead, a<br />
single valve should be installed for an entire fl oor or<br />
branch in a building to regulate an entire zone.<br />
To ensure your system can be controlled by a<br />
Hydromat DP, they are available in two fl anged<br />
and two BSP threaded versions, all with their own<br />
presetting pressure<br />
options.<br />
The two BSP threaded<br />
versions are available<br />
in DN15-DN50, with<br />
presetting options of<br />
5-30kPa or 25-70kPa.<br />
The fl anged versions suit DN65-DN100 with<br />
presetting options of 20-100kPa or 40-180kPa.<br />
All Hydromat DP’s can operate to a maximum<br />
working temperature of 120°C and are constructed<br />
of either a cast iron (fl anged) or bronze (BSP) body,<br />
bronze bonnet, DZR resistant brass stem and a<br />
stainless steel seat and soft seal disc.<br />

ensure you can easily fi nd all of your regular gas<br />
spare parts or any of the 3,300 products available<br />
from the Gas Solutions team.<br />
