Jacketed Globe Valve Manufacturers for High-Temperature Thermal Oil Service
A standard globe valve dissipates heat quickly through its body, so residual medium cools and solidifies during shutdown, and the valve cannot be operated when the system restarts. The jacketed globe valve solves this problem by welding a metal jacket onto the valve body and circulating steam or thermal oil through it, keeping the internal medium at the required temperature. It is a key isolation device for high-temperature thermal oil systems.The main globe valve product names of China globe Valve Network include:Electric Cast Steel Self-sealing Tightly Globe Valve,Flange,Welding Water Sealing Globe Valve,Flange Straight-through Copper Globe Valve,Forged SteelStraight-through Globe Valve,Flange Straight-through Ammonia Globe Valve,Flange Fluorine-lined Globe Valve,Flange Straight-through Low Temperature Globe Valve,Flange Straight-through Throttle EmptyingGlobe Valve,Flange, Internal Thread Straight-through Plastic Globe Valve.
Core Design Points of the Jacket
The jacket of a thermal oil globe valve is typically welded between the two valve flanges, with two connection ports on the side or bottom for steam or thermal oil inlet and outlet. The jacket is usually a welded carbon steel pipe structure, which is more pressure-resistant and robust than a cast jacket. A full-body jacket design provides more uniform heat preservation, ensuring the valve body, seat, and packing area all receive effective heating. For thermal oil service, the temperature of the heating medium circulating in the jacket should match the main pipeline, avoiding local overheating that could cause thermal cracking of the medium.

Selection Guidelines
When selecting a valve, confirm that the jacket pressure rating matches the heat source supply; thermal oil jackets are typically designed for 1.0 MPa or lower. The body material must be compatible with the thermal oil. Carbon steel is suitable for most mineral-oil-based thermal fluids, while stainless steel is appropriate for synthetic thermal fluids or where corrosion risk exists. Port locations should allow convenient connection to the heat source piping, and side ports facilitate inspection and maintenance. For systems requiring automatic control, electric or pneumatic actuators can be specified.
The jacket design of the insulated globe valve is the key to preventing medium solidification and ensuring reliable valve operation in thermal oil systems. Manufacturers including Shanghai Qizhong, Shanghai Huquan, GIM FLUID, Vcore, and KLINGER all provide jacketed globe valve products. When selecting a valve, focus on the jacket pressure rating, compatibility of the body material with the thermal oil, and whether the port locations allow convenient connection to the heat source.Do you still need to know or purchase the following globe valve products:
