Mainly used in petroleum, chemical, metallurgy, pharmaceutical and other types of systems, can keep warm and prevent the medium from crystallizing to transport high viscosity media that will solidify at room temperature.

1、The jacket is welded between the two flanges of the valve, and the connection port of the jacket is set on the side and bottom of the valve.

2、The size of connecting flange is one to two specifications larger than the connecting flange of ordinary valve of the same specification, and the structure length is the same as that of ordinary valve of the same specification.

3、Steam or other hot insulation medium can flow freely in the jacket to ensure that viscous medium can flow smoothly through the valve.
