UNIQUE FORM A step change in valve design, perfected over a decade of R&D. The Dilating Disk™ Valve employs a geometry unlike any other industrial valve on the market, 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, tight shutoff, and high cycle life while requiring minimal torque. With a valve body that is 50-80% smaller and lighter than the globe valves it is designed to replace, the Dilating Disk™ Valve provides the same CV (flow rate) at a significantly lower cost.

SAME FIT Plug and play with no added cost and zero risk. To eliminate switching costs, the entire Dilating Disk™ Valve product line conforms to the face-to-face dimensions for globe valves defined by the ISA 75.08 and ASME B16.10 standards.

BETTER FUNCTION By opening perpendicular to the flow of process fluids, the Dilating Disk™ Valve requires much less operating torque than other control valves; reducing actuator size and energy requirements. The proprietary design of the Dilating Disk™ Valve’s bonnet and stem leads to zero fugitive emissions when compared to “low emissions” globe valves, while eliminating the need for packing adjustments in the field.

MAIN BENEFITS:

-Lower pneumatic consumption (instrument air or process gas) for the valve actuation.

-Lower torque requirements for the valve actuators.

-Lower pressure drop for the same control valve capacity.

-Higher Cv for the same size of valves.

-The valve control element is designed and manufactured as a sort of cartridge.

-In DDV there is not ice formation as happens sometimes in standard globe control valve.
