Radiator valve set Honeywell DN15 angular version with thermostatic head, thermostatic valve and return valve

Angular radiator valve set Honeywell DN15 with thermostatic head, thermostatic valve and return valve is designed for controlling temperature and balancing flow in hot-water radiator systems. The set fits DN15 pipe connections and provides local temperature regulation at single radiators while allowing accurate flow adjustment during commissioning and balancing of heating circuits in residential and commercial installations.

Advantages

The angular configuration is space-efficient and suitable for typical radiator side connections. The thermostatic head enables automatic temperature control at the radiator based on the setpoint, reducing the need for manual intervention. The return (lockshield) valve allows precise balancing of the return flow to ensure even heat distribution across the heating system. Components are designed for compatibility with standard DN15 piping and for reliable operation in closed hot-water heating circuits.

Suitable for

• Individual radiator temperature control in residential apartments
• Balancing and commissioning of heating circuits in small commercial buildings
• Replacement or retrofit of existing DN15 radiator valves
• Systems where side (angular) radiator connections are required

Key specifications

• Connection size: DN15
• Configuration: angular (90°) radiator connection
• Set composition: thermostatic head, thermostatic valve, return (lockshield) valve
• Control: thermostatic temperature regulation at the radiator
• Function: flow control and hydraulic balancing of radiator circuits
• Application: closed hot-water central heating systems

How to use

Install the thermostatic valve on the supply side and the return valve on the return side of the radiator using DN15-compatible fittings, ensuring correct orientation for angular connection. Fit the thermostatic head on the thermostatic valve spindle and set the desired room temperature. During system commissioning, adjust the return (lockshield) valve to balance flow rates between radiators; mark final settings for future reference. Follow standard plumbing and heating safety procedures during installation, and flush the circuit to remove debris before final assembly.

Usage recommendations

For stable operation, avoid placing the thermostatic head in direct sunlight or directly behind curtains; ensure unobstructed air circulation around the head. Use the return valve adjustments together with system-wide balancing procedures to achieve even room temperatures. If replacing old valves, check compatibility of existing pipework and filtra­tion to prevent debris from affecting valve operation.
