Hunt Valve’s proportional poppet descale valve was named a 2016 Product of the Year Finalist by Plant Engineering magazine. The valve was among eight finalists in the fluid handling category.
The valve incorporates electromechanical actuation to precisely control the metering poppet’s speed and position, which eliminates water hammer and provides maintenance-free, reliable operation in the dirtiest systems. Utilizing a variable stroke profile enables one valve to perform multiple operations such as descale header control and header prefill functions.
By replacing all fast-closing poppet valves with the proportional poppet design and eliminating water hammer, plant managers can reduce annual plant operating costs by as much as 50% and decreasing unexpected downtime. To manage the high-velocity fluid flow, the valve has ceramic seating surfaces that prevent wear. The full ceramic seat is up to five times more durable than conventional seat materials, which maximizes the valve’s service life.
The valve’s electromechanical linear actuator avoids the maintenance and reliability issues commonly associated with all types of media-actuated valves. Since it uses an electrical actuator, it eliminates the moisture/contamination problems associated with pneumatic actuation.
