Accessories for Sanitary InstallationsFlamco’s Prescor B safety valves protect potable water systems from exceeding the maximum design operating pressure. Once the set pressure has been reached the safety valve will open to prevent a further rise in pressure. Prescor valves are produced in a variety of fi tting sizes and pressure ratings. The materials and construction of Flamco B safety valves are of the highest quality to ensure total safety and peace of mind. They can be used in combination with any boiler system.


PRESCOR B

Cap for lifting the valve.

Spring for setting the pressure of the safety valve.

Diaphragm that prevents moisture and dirt from getting

into the moving parts.

Valve with rubber seal.

Prescor Boiler Valves The Highest Quality of System ProtectionThe Prescor B and SB boiler valves protect sealed mains water systems against excess pressure. Such a safeguard is a requirement because of the expansion of system water and the presence of a non-return valve. Of course, water cannot be

compressed, so without this sort of safeguard the pressure in the system could rise to a dangerous level. Local regulations and standards and water pressures must be observed when using Prescor B and Prescor SB valves at all times.

Benefits• Solid brass housing.• Wide range, so the right valve can be used at all

times.• Because of the ''pop'' effect a high blow-off

capacity.• Can be used in combination with any storage boiler

system.• Construction and choice of materials are your

guarantee of safety.

How It WorksWhen the system pressure reaches the set pressure, the Prescor B boiler valve begins to vent, whereby the pressure stops rising. If, due to specific circumstances, the pressure rapidly rises over the set pressure, the Prescor B boiler valve will open fully,

creating a large blow off capacity. This is a permanent, reliable safeguard against overpressure. Venting can be prevented by fitting a suitably sized Airfix expansion vessel for sanitary systems.

All Prescor B and Prescor SB valves are individually tested to guarantee their function, and they comply with European Directive 97/23/EC, the Pressure Equipment Directive.

PRESCOR SB

The valve size of both the Prescor B and the Prescor SB is determined by the capacity

and output of the boiler.

Lifting lever.

The set pressure of the safety valve is locked and

cannot be changed.

To prevent limescale, the moving parts must be kept dry

in all circumstances. The diaphragm

ensures this.

Well Designed Technology and Application The seating of Prescor boiler valves is designed so that it not only makes a perfect seal, but can also achieve a large blow-off capacity. The hardness of the rubber is adapted according to the

set pressure of the safety valve. Due to this combination of a specifically designed seating and special rubber, it is possible to achieve optimum safety.

N.B. Prescor boiler valves must not be installed with the discharge port facing upwards.

Prevent Water Hammer Simply and EffectivelyThe Flexofit water hammer arrestor has been specially developed to absorb water hammer in sanitary mains water systems and is made of chrome-plated brass.

Some Possible Causes of Water Hammer• A valve (or solenoid) or tap closing too quickly.• The non-return valve.• A pump that suddenly cuts in or out.

Pressurized gas cushion.

Rubber diaphragm.

Water at system pressure

T-piece.

The Flexofit water hammer arrestor absorbs the wave of pressure before it can develop into water hammer. The Flexofit does this by having two areas that are separated by a rubber diaphragm. On one side, there is a gas cushion under pressure, while the other side is in connected to the system. The gas cushion compresses and absorbs the wave of pressure.

In combination with a wash hand basin Used with a washing machine

FLEXOFIT T-PIECE

Water hammer can be described as a change in pressure in a sealed pipeline as a consequence of sudden changes in the flow speed of fluid in the system. This creates a wave of pressure that moves rapidly through the line. This wave of pressure may result in the creation of vibrations, noise or even a fracture in the pipe or serious damage to equipment and pumps. It is thus important to prevent water hammer.
