I. Introduction valve system thermal heating system is an important part, but the valve is often a weak pipeline and the special concern of the site, part of the valve will be higher than other equipment repair or replacement frequency, demolition on the valve When installed, insulation materials are often mounted on the valve becomes valve maintenance difficulties, such as the insulation had to re-do or produce harmful fiber stimulation during removal or installation of insulation materials. We developed a removable insulation jacket can work together with the valve, you can completely avoid the above situation, not only the installation or removal easier, and can be reused and low cost, which are lightweight insulated jacket non-asbestos materials in confined areas can also be used. Whether it is ball valve, gate valve, butterfly valve can be installed removable insulation jacket. Usually the user name and provide valves DN size to order the appropriate insulation sets, special valves required to provide detailed specifications. Second, the product advantages: ● thermal performance in line with the "industrial equipment and piping insulation construction and acceptance norms" technical requirements GBJ 126 ● The removal and installation is easy, requires no special training, installing or removing a single set of time ≤ 5mins, save manpower in more than 50% ● can be used repeatedly, under normal circumstances, the service life of the valve sleeve can be inexpensive ≥ 10 years ● ● waterproof and acid, alkali, salt corrosion, can be used for indoor and outdoor use or underground pipe network ● non-combustible, flame retardant grade reach GB 8624-1997: B1 level, the German standard GI23009 flame level ● asbestos, are environmentally friendly heat insulation material three for valve: GB gate valve, globe valves, butterfly valves, piston valves, ball valves, filters, hydrophobic, breathing valve, such as different types of valves and flanges, elbows, tees, etc.
