The Insulated Lifting Plug Valve is a metal-seated lifting plug valve with an insulation layer for temperature-sensitive and viscous process fluids.
It combines lift-before-rotation operation with temperature insulation for applications where maintaining the process medium's temperature is important.

Insulation Configuration
Insulation Layer
The valve uses an insulation layer to help maintain fluid temperature under high- or low-temperature conditions. This configuration is intended for process media whose viscosity or physical state is affected by temperature.
Temperature-Sensitive Media
The insulated configuration is suitable for viscous or temperature-sensitive fluids where maintaining the process temperature helps preserve flow characteristics during valve operation.
Configurable Insulation
The insulation layer and valve configuration can be tailored according to the temperature requirements of the process medium. Material selection and other valve parameters can be confirmed together with the service conditions before production.
Lifting Plug Operation
Lift Before Rotation
The plug lifts 3–5 mm away from the sealing surface before turning. This separates the sealing surfaces during rotation and reduces direct sliding contact.
Reduced Operating Friction
The lifting sequence reduces contact between the plug and sealing surface during rotation, helping reduce operating torque and wear.
Reseat After Rotation
After the plug reaches the required flow position, the operating mechanism lowers it back onto the sealing surface for shutoff.
Applications
Chemical Processing
The valve is used for corrosive and temperature-sensitive fluids where the process medium requires temperature maintenance.
Refining
It handles high-temperature oils and hydrocarbons in refinery piping systems.
Food Processing
The valve can be configured for viscous or temperature-sensitive ingredients.
Asphalt Lines
The insulated configuration is used for sticky or semi-solid fluids such as asphalt.
Power Plants
The valve is used for heating and cooling fluid systems where temperature-sensitive flow conditions need to be maintained.
Quality Control
Material Verification
Body, plug and sealing materials are checked against the specified configuration and service requirements.

FAQ
Q: What information is needed for quotation and insulation configuration?
A: Please provide the valve size, pressure rating, process medium, operating temperature, material, connection requirements and ambient conditions.
Q: Can customer drawings be reviewed before production?
A: Yes. Customer drawings can be reviewed and confirmed before production for project-specific dimensions or configurations.
Q: What information is needed for actuator selection?
A: Valve size, pressure rating, operating torque, operating conditions and required control method should be provided for actuator selection.
Q: Can spare parts be supplied separately?
A: Yes. Replacement parts can be supplied according to the valve model and configuration.
Q: Can OEM or private-label requirements be supported?
A: Yes. Product marking and related manufacturing requirements can be coordinated for OEM or project orders.
Q: Can third-party inspection be arranged?
A: Yes. Third-party inspection can be coordinated when required by the purchaser or project specification.
Q: What is the MOQ for this valve?
A: MOQ depends on the valve size, material and configuration. Standard and project-specific requirements can be discussed with the sales team.
Q: What is the typical production lead time?
A: Standard configurations typically require 4–8 weeks for production. Special materials, insulation arrangements or project-specific requirements may require additional time and will be confirmed with the order.
