China High Velocity Pressure Vacuum Valve with Heating Device:

In accordance with the requirements of ISO15364, if the vessel navigates constantly in the poor ice conditions, it is very likely that the crystallization of the goods happens due to the vapor condensation.So that High Velocity Pressure Vacuum Valve should be required with the heating device. The heating is achieved by steam supplied by the vessel.

The heating device is with simple structure, can be heated rapidly & circularly with hot steam and thermal fluid less than 1.2Mpa.
