Thermostatic radiator valve SCHLOSSER DN15 1/2" straight, female-male connections (601200004)

Thermostatic radiator valve SCHLOSSER DN15 1/2" straight with female-male connections is a compact control fitting for hot-water central heating systems. The valve is designed to regulate radiator inlet flow according to the setting on a compatible thermostatic head, enabling stable room temperature control. Its straight body and 1/2" threaded female and male connections make it suitable for connection to standard DN15 piping and common radiator fittings used in residential and commercial installations.

Advantages

This thermostatic valve provides precise flow modulation to maintain set temperatures and reduce energy waste. The straight design simplifies piping runs and installation in confined spaces where angled valves would be impractical. Durable materials and a standard thread interface ensure compatibility with most radiator thermostatic heads and fittings, while the compact form factor minimises protrusion from the radiator connection.

Suitable for

• Replacement of thermostatic valves on radiators with DN15 / 1/2" connections
• Installation in residential hot-water central heating systems
• Use in small commercial premises with standard radiator fittings
• New radiator installations where a straight valve body is required

Key specifications

• Connection type: straight body with female and male threaded 1/2" connections
• Nominal diameter: DN15 (suitable for 15 mm piping)
• Function: thermostatic valve for flow regulation to radiator
• Compatibility: designed for use with standard thermostatic heads and radiator fittings
• Application: hot-water central heating systems for residential and commercial use

How to use

Install the valve in the radiator inlet piping with appropriate sealing on the threads and tighten to the manufacturer-recommended torque. Fit a compatible thermostatic head onto the valve spindle following the head manufacturer’s instructions. Set the thermostatic head to the desired room temperature; the valve will adjust flow automatically to maintain that setting. For replacement, isolate the heating circuit and drain the radiator before removing the old valve and fitting the new unit.

Usage recommendations

For reliable operation, pair the valve with a thermostatic head recommended for DN15 applications and check compatibility with existing radiator fittings. During installation, avoid over-tightening threaded connections and follow local regulations for heating system work. Periodic inspection for leaks and correct operation is advised, and service or replacement should be performed by a qualified technician when necessary.
