Insulation jackets are ideal to insulate butterfly valves. Not only do they protect butterfly valves from damage and heat loss, but they also make the workplace safer for you and your workforce. Hereandrsquo;s how great valve jacket insulation is, in our humble opinion. Saves Energy: Valves jackets are made with top-quality silicone glass cloth and contain 50mm Rockwool insulation.

This leads to energy savings, which in turn helps make your building energy efficient and reduces your carbon footprint. Safer Workplace: Since valve covers help reduce heat loss, they protect butterfly valves from condensation or sweating issues. This helps reduce instances where water drips from the valves and forms tiny pools, which can lead to accidents or mishaps, thus injuring personnel. Personnel is protected from coming in direct contact with the hot surface of the butterfly valves, thanks to these insulation jackets.
