Reliable transport for natural gas, corrosive and abrasive services

The metal-to-metal seating arrangement of Serck Audco valves has a proven track record of long-term durability and erosion resistance, even when handling high-velocity particles and impurities. This is particularly important when the valve is open against a high differential pressure.


An adjustable gland design, combined with high-performance graphite stem packing materials, ensures low emissions, even under extreme temperatures and extensive mechanical cycling.
