Butterfly Valve Insulation Jackets
1. Product Overview
Butterfly valve insulation jackets are custom-fabricated removable thermal covers engineered specifically to fit industrial butterfly valves, including wafer style, lug style, and high-performance eccentric designs. Constructed from high-temperature resistant coated fiberglass outer fabrics and filled with high-efficiency thermal insulation blankets, these covers prevent radiant heat loss in high-temperature steam lines and protect water pipes from freezing in cold environments. Designed with precise cutouts for handles, gear operators, and pneumatic actuators alongside secure fastening systems, they can be easily detached and reinstalled for routine valve inspection and maintenance without damaging surrounding insulation.
