Please Note

This is a manual valve, not a thermostatic one - it opens and closes to a fixed position set by hand and does not automatically respond to room temperature. If automatic temperature control is needed, choose a thermostatic radiator valve (TRV) instead.

Chrome-Plated Brass Body

Durable brass construction with a chrome-plated body, tailpiece and union nut for long-term reliability and a polished finish.

Is this a thermostatic or manual valve?

This is a manual valve. It's opened and closed by hand using the wheel head and stays at whatever position it's set to - it doesn't automatically adjust to room temperature the way a TRV does.

Can this be used as a lockshield valve?

This listing is for the manual control valve with a wheel head, not a lockshield. A lockshield cap is included, but it's supplied as a cosmetic cap for this valve rather than a separate balancing lockshield valve.

What pipework does this fit?

It's designed for standard 15mm pipework, with a straight configuration suited to pipes that run directly in line with the radiator connection.

Is it suitable for combination with a TRV on the same radiator?

Yes. A common setup pairs a thermostatic valve (like the Evolve or Elegance angled TRV) on one side of the radiator with a manual valve like this one, used as the lockshield-style balancing valve, on the other.
