Thermostatic Head SCHLOSSER HT White M28x1.5 for radiator valves

Thermostatic Head SCHLOSSER HT White M28x1.5 for radiator valves is a compact thermostatic actuator in a white finish designed to fit radiator valve bodies that accept an M28x1.5 connection. Intended for direct installation on compatible radiator valves, this thermostatic head enables manual regulation of room temperature through a presettable valve interface. The unit is suitable for use in domestic and commercial heating systems where individual radiator temperature control is needed.

Advantages

The SCHLOSSER HT thermostatic head offers straightforward temperature control with a standardized mechanical connection for reliable compatibility with valves using the M28x1.5 thread. Its neutral white finish integrates with most radiator designs while the compact form factor minimizes visual impact. The device provides consistent actuation of the valve spindle for stable regulation and is constructed for routine use in central heating systems.

Suitable for

• Residential radiator temperature control
• Small commercial or office heating systems
• Replacement of manual or worn thermostatic heads on compatible valves
• Individual room temperature regulation in multi-radiator installations

Key specifications

• Color: white
• Connection type: M28x1.5 threaded interface for direct valve mounting
• Control: mechanical thermostatic actuator with presettable temperature positions
• Mounting: direct attachment to compatible radiator valve spindle
• Application: designed for hot-water central heating radiators
• Form factor: compact head suitable for standard radiator valve assemblies

How to use

To install, remove the existing head (if present) from the radiator valve body, align the SCHLOSSER HT head with the valve spindle and thread it onto the valve using the M28x1.5 connection until firmly seated. Set the desired temperature position using the head's adjustable control. Operation is mechanical: the head modulates the valve spindle position according to the selected setting to regulate coolant flow and room temperature. Periodically check that the head moves freely and that the valve responds when settings are changed.

Usage recommendations

For reliable performance, ensure compatibility with the valve body thread and verify that the valve spindle is clean and free of corrosion before installation. Do not force the head onto a non-matching valve thread. For system maintenance, isolate the radiator and allow the system to cool before removing or installing the head. If precise temperature regulation is required across multiple rooms, combine these thermostatic heads with proper radiator balancing and a central room thermostat.
