Product Overview - Flamco

Prescor safety valves:
a complete range for the safety of your system
If you are looking for reliable safety valves, you need
look no further than Flamco's Prescor range. The
best protection for all sealed heating and chilled
systems from overpressure. The Prescor valves are
suitable for systems with a capacity of no higher than
580 kW at 3.0 bar. Systems with greater capacity will
need the heavy-duty Prescor S.
The benefits of Prescor
• High-quality materials and construction guarantee
reliable function when you need it most.
• If there is a rapid build-up of pressure, the valve will
'pop' open. The pressure can then be discharged
quickly.
• CE conformity mark.
• The opening pressure of all valves is individually
tested 100%.
Cap of high-impact
plastic.
Anti-ageing spring steel prevents the
set pressure from drifting.
Robust brass housing.
The diaphragm prevents moisture and dirt
from getting into the moving parts of the
safety valve during blowing off.
Valve seal of high-quality rubber, heat-resistant
to 140 ºC. The hardness of the rubber is
adapted to the set pressure of the valve. These
properties mean that the valve will not stick to
the valve seat.
PRESCOR
All Prescor safety valves are set to the specified
opening pressure during manufacture. This setting
cannot be adjusted. It is important to check the
requirements for the Prescor valve in advance.
When choosing a Prescor safety valve, the capacity
shown on the safety valve must exceed the nominal
boiler capacity.
The set pressure and maximum output for which the
valve is suitable are indicated on the valve.
Mount on the boiler, or as close as possible to it, in the supply
line. Never fit a stopcock between the boiler and the valve.
