Thermal insulation jackets are an ideal way to insulate gate valves, simply because, they minimise heat loss, protect and also help with the maintenance of the gate valves. Here’s why valve jackets are perfect, in our expert opinion:

Thermal Insulation: Valve jackets contain 50mm Rockwool insulation. The mineral wool with low thermal conductivity helps minimise heat loss in gate valves. They provide airtight insulation around the gate valves hence reducing energy consumption whilst also making the building more energy-efficient. This is particularly helpful in commercial and industrial environments.

Safer Workplace: Insulation jackets are made with high-quality silicone glass cloth for both outdoor and indoor applications. The top-quality glass cloth not only gives a neat, professional finish but also helps protect your workforce from direct contact with hot surfaces. Valve covers also help reduce condensation and sweating in valves. This, in turn, reduces instances where small pools of water are formed due to condensation that eventually leads to slips or accidents in the workplace.

Easy to Install and Maintain: Unlike traditional insulation, which is hard and rigid, insulation jackets are flexible and easy to use. They are also provided with velcro straps and pull cords which ensure that the jackets are snugly fit around gate valves to achieve maximum thermal efficiency. They can be just as easily reinstalled without any damage to the gate valves or loss of insulation.

  • The prices for the chilled/cold water valve jackets may differ from the ones displayed on the website. Chilled/cold water valves usually need to be wrapped with a vapour barrier, which would increase the jacket size and cost.
