Stirling Bold - Black Thermostatic Radiator Valve & Lockshield Corner 8mm

Control radiator warmth with greater precision

Give this radiator its own level of thermostatic control with the Stirling Bold Black TRV and lockshield set. The corner 8mm connection is designed for the appropriate pipe route, while the liquid sensor works with the valve to reduce hot-water flow when the room no longer needs as much heat.

Why choose these radiator valves?

• Fine-tune warmth one radiator at a time: The thermostatic head responds to room temperature and regulates hot-water flow through that radiator as the selected comfort level is reached.
• Avoid heating a room more than you need: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Give the heating system extra protection from freezing conditions: Its frost-protection function can allow some flow at very low temperatures, helping reduce the risk of water freezing in the radiator and nearby pipework.
• Avoid sourcing a matching lockshield separately: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Plan the radiator connection with the right valve shape: For pipework coming straight from the wall to a side-entry radiator, this corner layout keeps the connection compact.
• Tailor radiator output to the room's needs: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Get automatic temperature-responsive control: A liquid-filled sensor reacts as the room warms and cools, helping the valve adjust without constant manual intervention.
• Coordinate the valves with the radiator: The contemporary body shape is designed to complement modern radiators without adding unnecessary visual bulk. In matt Black, the set can be matched deliberately with the radiator finish or used as a contrasting detail.
• Add longer-term confidence to the purchase: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
