Cap de ventil termostatic DANFOSS 015G3090, mecanic, 8–28 °C

The thermostatic radiator valve head DANFOSS 015G3090 is a mechanical temperature control accessory designed for use with compatible radiator valves. Operating over a temperature range of 8–28 °C, this model enables direct, manual adjustment of room temperature without relying on electronic components. It is suitable for residential and commercial heating systems where simple, reliable regulation of radiator output is required to maintain comfort and support efficient energy use.

Advantages

This mechanical DANFOSS valve head offers robust, low-maintenance operation and straightforward temperature setting via a graduated scale. Its purely mechanical design eliminates the need for batteries or power supply, reducing potential points of failure. The device provides stable temperature control within the stated range and is compatible with common valve bodies when fitted correctly. Its compact form factor allows installation in confined spaces, and the construction materials are selected for long service life in typical heating environments.

Suitable for

• Rooms in residential apartments and houses where simple manual temperature control is preferred
• Commercial spaces with basic heating control needs, such as small offices or meeting rooms
• Systems requiring a mechanical alternative to electronic thermostats or where power-free operation is needed

Key specifications

• Temperature control range: 8–28 °C
• Type: Mechanical thermostatic valve head
• Operation: Manual adjustment with graduated temperature scale
• Power requirement: No external power or batteries required
• Design: Compact form suitable for standard radiator valve mounting
• Environment: Intended for indoor heating systems in residential and light commercial applications

How to use

Attach the thermostatic head to a compatible radiator valve body according to the valve manufacturer's instructions, ensuring a secure mechanical fit. Rotate the adjustment knob or dial to select the desired temperature setting within the 8–28 °C range; the valve will modulate radiator flow to maintain the selected room temperature. No electronic configuration or power connection is necessary. Periodically check the mechanical connection and clean any accumulated dust to ensure unobstructed movement of the control mechanism.

Recommendations

For reliable performance, confirm compatibility with your radiator valve body before installation and follow mounting torque and alignment guidance from the valve manufacturer. Avoid exposure to direct water spray or corrosive environments. If used in systems with thermostatic balancing or automated central controls, coordinate setpoints to prevent conflicting control actions. Regular visual inspection and gentle cleaning of the control head will help maintain accurate operation.
