I. Introduction

Thermal valve system is a very important part of the heat , but it is often a part of the valve in the pipeline and the need to focus on a particularly weak , some valves, and other equipment , compared with a higher frequency of repair or replacement , of the when the valve disassembly operations ,

On the installation of the valve insulation materials is difficult point for valve maintenance , and sometimes had to re-do the insulation , or is harmful fiber stimulation during removal or installation of insulation materials.

Second, the product performance:

1 , insulation properties must meet the "industrial equipment and piping insulation construction and acceptance of norms" of the technical requirements GBJ126 ;

2 , water and alkali, acid, salt corrosion, can be widely used in indoor and outdoor or underground pipe network ;

3 , the cycle can be used, in general, the service life of the valve sleeve may be greater than or equal to 10 years ;

4, no asbestos , environmental heat insulation materials are used ;

5 , installation and removal are quick and easy , no special training, installing or removing a single set of time less than or equal 5mins, the human can save more than 50% ;

6 , flame retardant rating to GB 8624-1997: B1 level , the German standard GI23009 retardant levels.

Third, the applicable valves:

GB valve, butterfly valve , piston valve , globe valve , ball valve , such as different types of valves .
