## Summary description

Thermostatic radiator valve head by Heimeier, model 4324-03.301, featuring an integrated valve and precise presetting for accurate flow control. Designed for use on radiators to regulate room temperature, it provides reliable modulation of heating output and simplifies balancing of heating circuits. Suitable for residential and commercial heating systems where stable temperature control and commissioning adjustment are required.

## Long description

The Heimeier thermostatic radiator valve head with integrated valve and precise presetting model 4324-03.301 is a compact control unit designed to regulate flow to individual radiators. It combines a thermostatic actuator and a valve body in a single assembly to deliver accurate modulation of heating output and to simplify commissioning and hydraulic balancing of heating circuits in residential and commercial installations. The device is intended for direct mounting on compatible radiator valves and offers stable temperature control through its presetting feature.
Advantages
This integrated valve head provides precise flow control with factory-calibrated presetting, reducing the need for additional balancing devices. The compact, all-in-one design reduces installation complexity and the number of connection joints. Built for compatibility with standard radiator valve interfaces, it enables predictable modulation of radiator output and supports reliable room temperature regulation. The presetting function allows installers to limit maximum flow rates for accurate circuit balancing during commissioning.
Suitable for
Residential central heating radiators
Small commercial or office radiator installations
Hydraulic balancing and commissioning of heating circuits
Upgrades where compact integrated valve solutions are preferred
Key specifications
Integrated thermostatic actuator and valve body for direct radiator control
Precise presetting mechanism for defined maximum flow and balancing
Compact form factor designed for standard radiator valve connections
Modulating flow control suitable for proportional temperature regulation
Material and finish compatible with common heating system requirements
How to use
Mount the valve head directly onto a compatible radiator valve following the manufacturer's torque and orientation recommendations. Use the presetting control to set the desired maximum flow for the radiator circuit during commissioning, then fit the thermostatic sensing head or set the control element to the required temperature setpoint. Operate the valve head as part of the room temperature control strategy; the integrated actuator modulates flow automatically to maintain the selected temperature.
Usage recommendations
During installation and commissioning, verify compatibility with the existing radiator valve body and ensure correct presetting to achieve hydraulic balance. Regularly inspect the unit for proper seating and absence of leaks. For optimal long-term performance, service and replace components according to the system maintenance schedule and follow local codes and installation standards.
