Wastewater air valves
Val-Matic’s full line of wastewater air valves perform two
important functions in a piping system: they maintain system
design efficiency and provide system protection.
Exhausting and admitting air keeps the system from restricted
flow, reducing pumping costs, and reduces the potential for
destructive surges and water hammer that can collapse a
pipeline.
Val-Matic’s wastewater air valves have guaranteed 316 stainless
steel floats and internal trim, fusion bonded epoxy coating to
minimise the build-up of sewage, and a non-clog design with a
2" clean out connection to facilitate the passage of solids, for
reduced maintenance.

Fully insulated and protected installations
Properly designed and insulated
HVAC installations serve as one of
the foundations of sustainable and
energy-efficient building. Designed for
demanding conditions, Paroc Hvac
Section AluCoat T meets a number of
requirements for a properly working
installation, as well as ensuring quick
and easy fitting.
Paroc Hvac Section AluCoat T is a
non-combustible stone wool pipe
section clad with an additional layer
of reinforced aluminium foil facing and
tape in the longitudinal seam, intended
for thermal and condensation insulation
of heating, hot and cold water, steam
and air-conditioning ducts and flues.
With low thermal conductivity, the
product helps builders and engineers
to minimise energy loss and enhance
efficiency in installations.
Apart from high thermal insulation
properties, the pipe section clad with
a layer of aluminium foil effectively
protects all metal surfaces of pipes
against water condensation. In addition,
Paroc Hvac Section AluCoat T is
classified with A2L-s1,d0 reaction to
fire class corresponding with the “non-
combustible material” classification,
meeting requirements set out for
technical insulations of installations.
Paroc Hvac Section AluCoat T is
characterised by high mechanical
strength. Stone wool pipe sections clad
with a reinforced aluminium layer do
not settle over time. The product is
claimed to maintain its thickness and
performance parameters for the lifetime
of the installation.
Standard thickness is 20-100mm, with
other thicknesses to order. The inner
diameter range is 12 to 612mm, and
pipe section length is 1,200mm.
Paroc manufactures energy-efficient
insulation solutions for new and
renovated buildings, marine and
offshore, acoustics and other industrial
applications. The company has
production plants in Finland, Sweden,
Lithuania, Poland and Russia, and sales
offices in 14 European countries.
