Cartridge
Diaphragm, O-rings, diaphragm washer, inner body and

Function
On the side of the valve outlet, the pressure acts via the diaphragm on the adjustable spring. A balance of forces is established via
the preloaded spring, which is set with the adjusting screw at the valve. If the outlet pressure increases above the specified value,
the piston is lifted against the spring force. The valve closes, and the outlet pressure is reduced. If the outlet pressure decreases
below the value, the piston is pushed down by the spring resistance. The valve begins to open, until the balance is reached again.
Independent of an increasing or decreasing inlet pressure, the outlet pressure remains constant to the greatest possible extent,
because it is not directly related to the inlet pressure.

Cartridge
Diaphragm, O-rings, diaphragm washer, inner body and
piston constitute the cartridge.
Function
The desired pressure in the valve inlet pipe is set by the adjustable spring force. If the inlet pressure rises above the set value, e.g.
due to an over capacity of the pump, the valve piston is lifted against the spring force. Consequently, the valve opens, and there is a
reduction of pressure in the outlet. If the pressure decreases in the valve inlet pipe, the spring resistance pushes the piston down in
the direction of the valve seat and closes, as soon as the inlet pressure sinks below the preset spring tension. In this way, a constant
pressure in the supply line is ensured.

6 Putting into operation
6.1 Preparation
►Flush piping system.
6.2 Pressure testing
The same instructions apply to the pressure testing of valves as to the pipe (see chapter „Processing and installation“ in Georg Fi-
scher Planning Fundamentals Industry).
1. Check that all valves are in the required open or closed position.
2. Fill the line system with test medium and carefully vent it.
3. Build up test pressure.
4. The valves and connections should be checked for a tight seal during the pressure testing.
5. After the successful leak testing: remove the test medium.
6. Document your results.
DANGER!
Piping system not tight!
Leaky connections can cause medium to escape and cause property damage and personal injury, as well as endanger the environ-
ment.
►Check the tightness of the connections before putting into operation.
►Periodic check that no medium escapes to the outside.
►Wear appropriate protective equipment.
DANGER!
Pressure too high!
Exceeding the maximum permissible pressure can damage the piping system, causing medium to escape and cause property dama-
ge and personal injury, as well as endangering the environment.
►The component of the piping system with the lowest PN determines the maximum allowable test pressure in the piping section.
►Take measures to prevent pressure surges.
►Wear appropriate protective equipment.
CAUTION!
Maximum permissible test pressure!
For the pressure test of valves in open position, the same instructions apply as for the piping system (max. 1.5 x PN, und max. PN +
5 bar), but the test pressure in closed valve position must not exceed max. 1.1 x PN.
►For detailed information, see the Georg Fischer Planning Fundamentals.
►After successful pressure test: Remove test medium.
►Record the results.
