This valve provides reliable flow control to individual radiators and is ideal for both domestic and commercial heating systems. Its angled configuration makes it suitable for pipework that approaches the radiator from the wall or at a 90-degree angle from the floor, offering a neat and space-efficient solution. The addition of a 1/2" nut tail enhances compatibility with a wide range of radiator fittings, making it a flexible choice for many installations.

Built for Everyday Performance

Constructed from durable and corrosion-resistant materials, this valve is built to withstand regular use and the varying temperatures found in heating systems. The valve body, union nut, and tailpiece are made from chrome-plated brass, giving it a polished finish and robust performance over time. Inside, the valve insert uses brass construction and features EPDM (Ethylene Propylene Diene Monomer) rubber seats, which ensure a tight, leak-free seal. The wheel head and lockshield cap are made from strong ABS plastic, making adjustments easy while maintaining a lightweight build.

Frequently Asked Questions

Can this valve be used on any standard radiator?

Yes, as long as the radiator has a compatible 15mm pipe connection and 1/2" tail fitting, this valve will fit most standard radiator systems.

What’s the difference between a wheel head and a thermostatic valve?

A wheel head valve offers manual control—you turn it to open or close the flow of hot water. A thermostatic valve (TRV) automatically adjusts based on room temperature, offering more efficient temperature control.

Is this valve suitable for both open-vented and sealed heating systems?

Yes, the Evolve Contract range is compatible with most domestic heating systems, including both open-vented and sealed (pressurised) systems, as long as pressure and temperature limits are observed.
