Insulation gate valve
The insulation gate valve features an integrated thermal jacket surrounding the valve body, preventing medium solidification and temperature loss. Designed for high-viscosity and temperature-sensitive fluids, it provides reliable sealing, smooth flow control, and enhanced energy efficiency in steam, thermal oil, asphalt, chemical, and industrial processing systems.
Insulation gate valve
The Insulation Gate Valve, also known as a Jacketed Gate Valve, is specially designed for pipelines carrying media that require temperature maintenance during operation. The valve body is equipped with an external insulation jacket through which steam, thermal oil, hot water, or other heating media circulate to prevent solidification, crystallization, or viscosity changes.
Featuring a full-port gate design, the valve ensures minimal pressure loss and reliable shut-off performance. Manufactured from high-quality carbon steel, stainless steel, and alloy steel materials, insulation gate valves provide excellent durability and corrosion resistance under demanding operating conditions.
These valves are widely used in chemical processing, petrochemical plants, asphalt production, food processing, pharmaceutical manufacturing, and other industries where maintaining media temperature is critical.
As a professional industrial valve manufacturer, we offer complete OEM and ODM services.
All insulation gate valves are manufactured and tested according to international quality standards.
