Regulate the circuit.
Compare the flow target with a measured response. Adjust the valve within the operating and control limits agreed for the application.
Standalone flow control
Automatic flow valve.
Raise the flow target to lift the plug and let more coolant through.
Inside the flow valve
One defined circuit
Control the opening.
Verify the flow.
A standalone valve for automatic flow regulation, temperature and pressure monitoring, and thermal power and energy monitoring using a configured glycol profile. In operation, measured flow closes the loop; valve position alone does not prove the flow.
Read the conditions.
Keep flow, temperature and pressure with their measurement points. Telemetry provides the context for the connected control or monitoring system.
Account for the fluid.
Glycol type, concentration and temperature affect fluid properties. Use a confirmed profile when interpreting thermal power and energy.
Thermal context
From a flow reading
to a useful calculation.
Thermal power depends on more than flow. Combine volumetric flow with fluid density, heat capacity and the temperature rise across the defined load.
- Measure
- Flow, supply temperature and return temperature, with known locations, units and calibration.
- Confirm
- The coolant type, glycol concentration, whether concentration is by mass or volume, and the fluid-property reference.
- Interpret
- Apply the appropriate properties for the fluid and temperature. Integrate valid thermal power over time when thermal energy is required.
Glycol compensation keeps the fluid assumptions explicit. It does not change the coolant blend, automatically identify concentration or establish a sensor accuracy rating.
Valve questions
Clear signals.
Clear boundaries.
Define the controlled circuit and the measurements before choosing the component.
How is the valve different from the manifold?
The valve is a standalone component for automatic flow control in a defined circuit. The automatic manifold adds supply and return headers and multiple branch connections, with integrated monitoring and control.
Does a commanded valve position prove the flow?
No. The opening is a command or position signal. Actual flow also depends on the available pressure, the connected load and the rest of the circuit. Use the measured flow response as feedback.
What is needed to monitor thermal power and energy?
Use measured flow, supply and return temperatures at agreed points, and density and heat capacity for the confirmed fluid profile. Thermal power is approximately density × volumetric flow × heat capacity × temperature rise. Integrating valid thermal power over time gives thermal energy. Flow alone is not an energy measurement.
Does glycol compensation detect or change the concentration?
Not by itself. Compensation uses the confirmed glycol type, concentration basis and temperature-dependent properties in calculations. Automatic concentration detection is a separate sensing requirement. Flow-meter correction depends on the sensor, calibration and coolant.
Does the valve create circulation or replace the cooling system?
No. It regulates flow within the hydraulic conditions provided by the cooling system. Confirm the available pressure, circuit losses and required flow together.
What needs to be agreed before selection?
Confirm the controlled circuit, coolant profile, flow target, sensor positions, pressure and temperature limits, connection arrangement, actuator and telemetry interfaces, override and fault response. Validate the arrangement against the connected equipment requirements.
