Isolation Valves & Expansion Joints for COG Transmission System
RWE Power AG · Huckingen Power Plant · Duisburg, Germany
Our partners at Enemona AD were contracted by RWE Power AG for the full-scope design, construction, and engineering of an extension to the coke oven gas (COG) transmission system at the Huckingen power plant in Duisburg, Germany. PS Technik supplied the isolation valves and expansion joints for the project.
Equipment Supplied
- Triple-offset butterfly valve DN 300 PN 10, pneumatically actuated — ×1
- Triple-offset butterfly valve DN 500 PN 10, pneumatically actuated — ×1
- Lenticular steel expansion joints, DN 600 to DN 900, PN 10
Triple-offset butterfly valves provide bubble-tight isolation through a metal-to-metal seat with zero friction on the sealing face. The triple-eccentric disc geometry eliminates contact between disc and seat during rotation, making them suitable for high-temperature, high-cycle duties. Standard applications include power generation, district heating, petrochemical, steelworks, and pulp & paper.
