Hygienic Valves
GEA IO-Link
IO-Link is the first globally standardized IO technology (IEC 61131-9) to communicate with sensors and actuators.
The powerful point-to-point
communication is based on the long-known 3-wire sensor and actuator connection
without any additional requirements for the cable material. Therefore, IO-Link
is not a field bus, but the evolutionary advancement of the existing and proven
connection technology for sensors, actuators and thus also for control tops of
the latest generation.
Sensors and actuators
can communicate
Process data
will be digitally exchanged with high signal quality.
Components can
be centrally parameterized.
Diagnostic
information can be transferred from the valve to the controller.
End to complex
wiring
Standardized
and considerable simplified installation.
IO-Link is field bus-independent and can be integrated into all field buses worldwide.
Constant Pressure Valve VARIVENT® , Type DHV
VARIVENT® constant
pressure valves are used to adjust the inlet pressure of the valve on a
constant level. In case of any process-related pressure fluctuations, the valve
opens or closes to compensate them. The needed product pressure will set
through the air supply pressure to the actuator. Therefore a constant air
control pressure is required.
Function
As
soon as the product pressure operating on the ring face of the valve disc is
higher than the closing force set through the air supply pressure of the
piston, the VARIVENT® constant pressure valve opens. If the product pressure
decreases, the valve automatically closes and creates a constant pressure in
the inlet nozzle.
Additionally
the lower part of the valve disc is provided with a control cone to optimize
the valve characteristics.
The
valve disc of the constant pressure valve is made of PTFE, which has a good
resistance against aggressive media and only has a low friction during the
movement.

Application Examples
In
practice VARIVENT® constant pressure valves are used to keep a constant product
pressure at the outlet of a separator. At this juncture the self-regulating
VARIVENT® constant pressure valve is a lower priced alternative to a modulating
control valve. Since the valve operates automatically after setting the
demanded product pressure, no additional pressure transmitter is necessary.
The
VARIVENT® constant pressure valve is additionally used to keep the demanded
product pressure in heat exchangers.
Extra Equipment
The
valve can optionally be equipped with a quick-air-exhaust or a precision
pressure regulator. Via the supply- or exhaust air quantity a precise setting
of the air supply pressure above the piston surface is possible, which allows
the regulation of the demanded constant product pressure at the inlet side of
the valve.
