Product Detail

The Insulation Jacket Fully Welded Ball Valve is a high-performance flow control solution designed specifically for media that require precise temperature maintenance. By combining a monolithic fully welded body with a high-efficiency heating jacket, this valve eliminates the risk of external leakage while preventing fluids (such as liquid sulfur, bitumen, or heavy oil) from solidifying or crystallizing. It is the gold standard for district heating, molten media transport, and urban gas networks where thermal integrity and safety are paramount.

Design Description

Integrated Insulation Jacket: The outer jacket allows for the circulation of steam, thermal oil, or hot water, ensuring the process media remains at a stable, flowable temperature.
Zero-Leakage Welded Body: The fully welded construction replaces traditional bolted flanges, eliminating potential leak paths and making the valve ideal for buried or hazardous services.
Maintenance-Free Design: High-strength forged steel and self-lubricating PTFE/PEEK seats ensure a long service life without the need for regular tightening or adjustment.
High Thermal Efficiency: The jacket covers the valve body from flange to flange (or end to end), minimizing "cold spots" where media could potentially harden and jam the ball.
Buried Service Capability: Often supplied with an extended stem to allow for below-ground installation in district heating networks while keeping operators safe at the surface.
