Delayed Coking Top Unheading Valve

True Double Block and Purge for Enhanced Safety and Efficiency

IMI Z&J’s Delayed Coking Top Unheading Valve is based on a well-established Double Disc Through Conduit Gate Valve design, ensuring reliable performance in severe delayed coking applications. This valve is engineered to handle high-pressure requirements and frequent cycling with minimal wear, providing an efficient and safe solution for refining operations.

• Double block and purge: Two independent discs ensure true double block and purge, maximising safety and tight sealing.
• Thermal distortion resistance: The double-disc design reduces thermal distortion, requiring less steam and resulting in less erosion.
• Active mechanical seating force: Ensures high tightness for secure operation in demanding environments.
• Corrosion & wear resistant: Hard-faced seats designed to resist wear, ensuring long-term durability.
• No cooling water required: Simplifies operation and reduces maintenance costs.
• Actuator options: Available with electric or hydraulic actuation.
• Minimal spare parts: Designed to reduce maintenance requirements.
