Double Eccentric Control Plug Valve, DN25-DN100, 1-4 Inch

Key Specifications / Features

The eccentric rotary plug control valve boasts a one-piece body design, adaptable for connection via flanged (ASME Class 150 LB / PN25) or wafer type (ASME Class 150 LB/ PN25) configurations. This valve type features a uniquely shaped plug that maintains a slight distance from the valve seat until near closure, enhancing dynamic alignment for optimal shut-off. Commonly referred to as eccentric plug valves, they incorporate a plug-shaped component following an eccentric path during rotation. This design ensures minimal contact between the plug and seat until just before closure, facilitating precise cutoff as sealing surfaces dynamically align. Widely employed in applications handling slurries, grit, or solids, these valves offer superior control accuracy and wide rangeability, complemented by pneumatic actuators, digital/smart positioners, and air filter regulators for meticulous flow control.
