Thermostatic Radiator Valve Head Varioterm GS.10-06C M30x1.5

The Varioterm GS.10-06C thermostatic radiator valve head with M30x1.5 thread is a temperature control accessory for radiators that replaces or upgrades manual valve heads. It senses ambient temperature and modulates the valve spindle to maintain the selected setpoint, reducing overheating and providing steady room temperatures. The device is compatible with radiators and valve bodies using an M30x1.5 connection and is intended for residential and light commercial heating installations.

Advantages

This thermostatic head offers automatic temperature regulation without continuous manual adjustment, improving comfort and energy efficiency. The compact design and standard M30x1.5 thread make it straightforward to install as a replacement part on compatible radiator valves. Its mechanical sensing element provides reliable control without requiring electrical power, and the calibrated scale enables accurate setpoint selection for varied room conditions.

Suitable for

• Residential radiators with M30x1.5 valve connections
• Light commercial spaces such as small offices or meeting rooms
• Replacement of manual radiator valve heads
• Heating systems where passive thermostatic control is preferred

Key specifications

• Connection thread: M30x1.5 for direct mounting on compatible valve stems
• Control type: Mechanical thermostatic head that reacts to ambient temperature
• Adjustable setpoint: Calibrated control scale for selecting desired room temperature
• Power: Passive operation; no external electrical supply required
• Application: Designed for use on domestic and light commercial radiators

How to use

Fit the thermostatic head onto a compatible valve stem with M30x1.5 thread by removing the existing manual head and screwing the device into place until secure. Select the preferred setpoint using the control scale; the head will expand or contract in response to room temperature and actuate the valve spindle to maintain that setpoint. Periodic visual checks are sufficient to ensure correct operation; if the valve stem or adapter is damaged, replace it before mounting the thermostatic head.

Usage recommendations

Install in positions with free air circulation and away from heat sources like direct sunlight, lamps, or drafts to ensure accurate temperature sensing. When replacing an existing head, verify the valve connection size and compatibility with M30x1.5 thread; use appropriate adapters if required. For system maintenance, isolate the radiator and follow manufacturer guidance for valve stem inspection and replacement.
