Serck Audco Super H plug valves are heavy-duty, lubricated plug valves designed for reliable isolation in high-pressure and high-temperature applications. Manufactured by Flowserve, the Super H range is built to deliver robust performance in demanding process environments. These valves utilise a pressure-balanced, lubricated plug design, which reduces operating torque and ensures smooth operation even under severe service conditions. The injection of sealant not only minimises wear between the plug and body but also enhances sealing performance, providing dependable, bubble-tight shut-off.

Features:

• High reliability and certainty of zero leakage sealing down the line achieved by large, metal-to-metal seat mating areas and precise seat mating procedures
• Increased uptime from pressure-balanced plug design that utilizes pressure to balance the forces acting on the plug and prevent taper locking
• Lower maintenance costs via in-line maintainable design that allows sealant to be injected with the valve in any position and under pressure
• Longer service life through seat protection against line media while the valve line is open
