Standard flow regulators
Low-pressure flow regulators
Adjustable flow regulators
Standard flow regulators maintain a virtually constant flow rate within the pressure
range of 1 to 10 bar. They are available in
diameters of 7 to 22 mm for flow rates of
0.25 to 100 l/min. You can choose between
various designs with axial or radial seals.
Special types are available upon request.
Special flow regulators have been developed
for low-pressure applications (0.25 to 4 bar).
Unlike standard flow regulators, low-pressure flow regulators regulate the flow rate
significantly below 1 bar.
As the name suggests, the D-type flow
regulator offers a means of adjusting the
flow rate. The range of adjustment may
be specified by the customer.
It is used as a flow control valve in instantaneous water heaters and other applications
in order to compensate extreme differences
in the temperature of the incoming water
(e.g. winter / summer).
example: solenoid valve
Time-controlled solenoid valves can be combined with pressure-compensating flow regulators, which maintain a virtually constant flow rate, to enable the accurate metering of liquids
required for beverage dispensing machines and electronic faucets, for example.
Use in water-saving products: the flow regulator controls the volume of water in the shower
or at the sink, ensuring that less water flows. Comfort and convenience for the user is
noticeably improved at the same time, as water continues to be virtually evenly distributed,
even if several outlets are used at the same time (e.g. washrooms in public buildings).
example: water heaters/boilers
Flow regulators maintain a constant flow of cold water to the water heater in spite of varying
inlet pressures. This is a prerequisite for maintaining a constant temperature.
example: isolating valves
A flow regulator may be fitted on the inlet or outlet side of an isolating valve, or in the ball
valve itself. Certain isolating valves can be accessed in the closed position without having to
drain the water from the system first. In this case, the flow regulator can be removed or
replaced easily within the framework of maintenance work.
Flow regulators in isolating valves offer a means of achieving constant control of the flow in
downstream applications to the greatest extent possible.
