## Long description

Thermostatic radiator valve set Comap 3808W5428 with angled 1/2" connection is a compact control solution for hot-water radiator installations. The set includes the valve body and thermostatic control components designed to regulate coolant flow to the radiator and maintain the desired room temperature. Its angled configuration suits installations where space behind or beside the radiator is limited and a right-angled pipe entry is required.
Advantages
The angled design allows for space-saving installation in tight layouts and simplifies connection to existing pipework. The thermostatic control provides automatic modulation of flow according to the selected setpoint, improving temperature stability and reducing energy consumption compared with manual valves. Constructed from materials suitable for heating systems, the valve set is intended for reliable operation with standard hot-water heating media.
Suitable for
Residential radiator installations with limited clearance behind the appliance
Commercial heating systems where angled connections simplify piping routes
Replacement of manual radiator valves to enable thermostatic control
Applications requiring 1/2" threaded radiator connections
Key specifications
Connection type: angled, 1/2" thread for radiator inlet
Control: thermostatic valve set with removable thermostat element
Application medium: hot-water central heating systems
Mounting orientation: angled installation suitable for side or bottom pipe entry
Compatibility: designed for standard radiator valve seats and fittings with matching thread
How to use
Install the valve body onto the radiator inlet ensuring the 1/2" threaded connection is tightened to the correct torque and sealed according to local plumbing practice. Fit the thermostatic control element onto the valve body; adjust the setpoint by turning the thermostat head to the desired temperature marking. After installation, purge air from the radiator and check for leaks. Regularly operate the thermostat control through its range to prevent sticking and to maintain correct operation.
Usage recommendations
For optimal performance, use with clean, treated heating water and ensure the system is balanced. When replacing existing valves, verify thread compatibility and adapt sealing methods as required. Periodic inspection and occasional manual cycling of the thermostatic element help sustain accurate temperature control.
