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 up to 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.

•

If there is a rapid build-up of pressure, the valve will

'pop' open. The pressure can then be discharged

quickly.

•

CE conformity mark (PED 97/23/EC).

•

The opening pressure of all valves is individually

tested.

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

adapted to the set pressure of the valve. These

properties mean that the valve will not stick to

the valve seat.

SAFETY VALVES

Prescor safety valves have a special shape, which not only achieves a perfect seal, but also a large blow off capacity. The valve

seal is made of high quality rubber, which is heat resistant to 140 °C, and where the hardness of the rubber adjusts to the set

pressure of the safety valve. In this way, the valve cannot stick to the seat.

All valves are tested before they leave our facility and are available for heating and cooling installations, as well as for protection

of various hot water storage appliances. For safety valves for potable water installations see "Accessories for potable water

systems".
