Radiator Valves

Radiator valves are valves and heads that open and close hot water to the radiator, adjust it to room temperature and balance the circuit on the return side.
They are used in central heating systems of homes, offices and public buildings. The group includes thermostatic valve bodies and heads, manual radiator valves, return valves, smart digital heads and compact radiator inserts.
Main Applications
- Residential central heating
- Office and school radiators
- Valve renewal in renovations
- Energy saving projects
- Panel radiator connections
- One and two-pipe systems

Material Options
| Part | Thermostatic radiator valve | Manual / return radiator valve |
|---|---|---|
| Body | Nickel-plated brass | Brass, nickel or chrome plated (depending on model) |
| Stem | Chrome steel, in O-ring | Depending on model |
| Control | Thermostatic head or electrothermal actuator | Handwheel or key setting |
| Connection | Rp female × union male | Union, straight or angle |
Which material? Values come from the manufacturer sheet of the parent category. With thermostatic valves, body and head must be from the same system, and a suitable adaptor must be used for PEX or copper pipe.
