AMPO POYAM Dilating Disk Control Valve

AMPO POYAM Dilating Disk Control Valve

A Dilating Disk Control Valve is a type of industrial control valve that regulates the flow of a fluid or gas by using a mechanism in which a disk or series of disks expand radially (dilate) to vary the flow area. The operation involves either a single disk that flexes outward or multiple interlocking segments that move apart, increasing or decreasing the size of the opening through which the medium flows.

AMPO POYAM Dilating Disk Control Valve employs a unique trim geometry, providing best-in-class, dynamic process control from a quarter-turn stem. Three interlocking Petals form the aperture of the Dilating Disk Valve. They open perpendicular to the flow of process fluids. The mechanical operation of the valve is driven by a rugged and efficient Ring Gear, which delivers precise throttling, consistent shutoff, and high cycle life while requiring minimal torque.

AMPO POYAM Dilating Disk Control Valve have size 1/4” up to 30” with material option carbon steel, stainless steel, duplex and super-duplex, nickel-based Alloys and specialty materials with pressure class 150 lbs up to 1500 lbs. Commonly used in industrial processes for Oil and Gas, Power Plant, Chemical and Petrochemical.
