Thermostatic angled valve FERRO 1/2" model 401402 for radiators and heating systems

Thermostatic angled valve FERRO 1/2" model 401402 for radiators and heating systems is an angled thermostatic control valve designed to regulate the flow of hot water to radiators and heating elements. Intended for use at the radiator connection point, the valve provides local temperature regulation by adjusting the flow rate, helping to balance room temperatures in residential and commercial heating installations. The design suits standard 1/2" threaded radiator fittings and integrates with common central heating pipework.

Advantages

The valve offers precise flow control and stable temperature regulation at the radiator inlet, reducing the need for repeated manual adjustments. Its angled configuration allows compact installation where space behind the radiator is limited, and the thermostatic mechanism responds to temperature changes to maintain set conditions. Constructed for compatibility with standard fittings, the valve simplifies replacement or upgrading of existing radiator connections.

Suitable for

• Regulating individual radiator temperature in apartments and houses
• Balancing room temperatures in small commercial premises
• Replacement of existing angled radiator valves with 1/2" connections
• Integration into central heating circuits where local control is required

Key specifications

• Connection type: angled radiator valve with 1/2" threaded connection
• Function: thermostatic flow regulation for radiator inlet
• Installation orientation: angled, suitable for tight space behind radiators
• Compatibility: designed for use with typical residential and commercial heating pipework and radiator fittings
• Control: mechanical thermostatic mechanism responding to local temperature

How to use

Install the valve at the radiator inlet in place of the existing angled valve or with compatible 1/2" threaded fittings. Ensure the heating system is depressurised and cooled before removing any fittings. Tighten joints to manufacturer-recommended torque values and check for leaks after pressurising the system. Adjust the thermostatic head to the desired setting to obtain required room temperature; the valve will modulate flow automatically in response to temperature changes.

Usage recommendations

For reliable operation, use with properly flushed and maintained heating systems to avoid debris or deposits that can impair valve function. Periodic inspection for leaks and correct thermostat response is advised. When replacing valves, confirm thread compatibility and, if necessary, use appropriate adapters or sealing materials rated for heating systems.
