Thermostatic valve SCHLOSSER DN 15 1/2" x 1/2" right-hand (model 6012 00006)

Thermostatic valve SCHLOSSER DN 15 1/2" x 1/2" right-hand (model 6012 00006) is a compact temperature-regulating valve designed for use in hot-water heating systems. It controls flow automatically according to the position of a thermostat head, offering stable room temperature regulation for radiators and small hydronic circuits. The valve features a right-hand in/out orientation and 1/2" threaded connections suitable for standard residential plumbing installations where a DN15 valve is required.

Advantages

The SCHLOSSER DN 15 thermostatic valve provides automatic modulation of flow to maintain set temperature without constant manual adjustment. Its compact DN15 body makes it suitable for tight installation spaces and standard 1/2" threaded connections simplify replacement and retrofit. The right-hand orientation allows straightforward piping layout in installations where inlet and outlet positions are defined. The valve construction supports reliable operation in typical residential heating systems and reduces energy waste by preventing overheating.

Suitable for

• Domestic radiators in apartments and houses
• Small hydronic circuits and underfloor manifold manifolds of limited flow
• Retrofit projects replacing existing 1/2" valves
• Installations requiring a right-hand oriented valve with DN15 compact size

Key specifications

• Connection size: 1/2" x 1/2" threaded
• Nominal diameter: DN15
• Orientation: right-hand
• Application: thermostatic temperature regulation for hot-water heating
• Installation type: in-line valve for radiator or hydronic circuit

How to use

Install the valve in the radiator or hydronic circuit with the correct right-hand orientation and tighten the threaded connections according to pipe manufacturer recommendations. Attach a compatible thermostatic head onto the valve spindle and set the desired room temperature. The valve will automatically modulate flow based on the thermostatic head position; minimal manual intervention is required once properly set. Flush and prepare the heating circuit before installation to prevent debris from affecting valve operation.

Usage recommendations

For reliable function, pair the valve with a thermostatic head from the same performance class and follow the heating system commissioning procedure. Ensure the system is clean and deaerated, and use appropriate sealing materials on threaded joints. If replacing an old valve, check that pipe alignment and dimensions match DN15 1/2" connections to avoid stress on fittings.
