Hill Insulation

Hill Insulation Valve Jackets

Our Hill Insulation collection features insulated valve jackets made by our in-house manufacturing team, for both internal and external use. Hill Insulation is now Hill Grwp Ltd, and Insulation & More operates as part of Hill Grwp Ltd.

Valve jackets are fitted over valves on insulated pipework, so that the valves are insulated along with the pipe insulation either side of them. The collection covers bore sizes from 6mm to 324mm, and you can use the bore size filter to find the right fit for your pipework.

Internal Valve Jackets

Our internal valve jackets are made for indoor use, with styles including jackets for screwed ball valves and flanged gate valves. The jacket for screwed ball valves, for example, uses 50mm of insulation for temperatures from 10°C to 100°C, with fire-retardant Velcro straps and Nomex pull-cords. Outer fabric options include grey silicone-coated fibreglass cloth, silver foil cloth and black polyurethane-coated nylon.

WeatherPro External Valve Jackets

Our WeatherPro valve jackets are made for external use, for valves on outdoor pipework. For more advice on protecting outdoor pipework, read our guide on how to weatherproof pipe insulation.

Actuator Covers and End Capping

The collection also includes our weatherproof actuator cover, which fits over a valve actuator, and aluminium end capping for pipe insulation. If you would prefer a rigid metal cover for your valves, take a look at our aluminium valve box.

Bespoke Valve Jackets

If you have a non-standard valve, our team can help with made-to-spec jackets. Find out more on our thermal valve jackets page.
