Product Overview
Y-Pattern Insulated Globe Valve is an industrial globe valve with an insulated jacket, designed for shut-off and flow control in process pipelines requiring continuous temperature maintenance.
Product Features
The Y-pattern flow path reduces changes in flow direction, allowing high-viscosity media to pass through the valve more smoothly.
The jacket surrounds the main flow passage to maintain media temperature, helping prevent solidification, crystallization and viscosity increase inside the valve.
The seat sealing area is kept under continuous thermal protection, reducing media build-up on the sealing surfaces and maintaining proper disc-to-seat contact.

Selection & Maintenance Guide
Jacket Heating Selection
Select steam or thermal oil according to the media solidification point and operating temperature to maintain proper media flow inside the valve.
Jacket Connection
Connect the jacket inlet and outlet correctly and maintain continuous circulation of the heating medium for uniform temperature distribution.
Shutdown Maintenance
For media prone to solidification, keep the jacket heated or drain the valve cavity before shutdown according to process requirements.
FAQ
Q: What media is the Y-Pattern Insulated Globe Valve suitable for?
A: It is suitable for bitumen, heavy oil, resin, wax and other process media requiring continuous temperature maintenance.
Q: When should an insulated globe valve be selected?
A: It is recommended when the process media tends to solidify, crystallize or become significantly more viscous as the temperature drops.
Q: What heating media can be used in the jacket?
A: Steam or thermal oil is commonly used, depending on the required process temperature and media characteristics.
Q: What is the advantage of the Y-pattern design?
A: The Y-pattern flow path reduces changes in flow direction, making it more suitable for transporting high-viscosity media while reducing media retention inside the valve.
Q: What inspections are performed before shipment?
A: Each valve undergoes shell strength and seat leakage testing before shipment. Material certificates, pressure test reports and related technical documentation are available upon request.
