HTJ Insulated Jacketed Single-Seated Control Valve
The HTJ insulated jacketed single-seated control valve has the same performance as the HTS control valve and is mainly used in thermal insulation occasions. When the crystallization temperature of the process medium is lower than the ambient temperature, or the fluid temperature drops, causing an increase in viscosity or solidification of the fluid, a steam insulation jacket device is added to the valve body and upper valve bonnet of the control valve to ensure that the process proceeds as required.
