Hunt Valve, a fluid power engineering company specializing in severe-duty valves and components, has released a new descale valve that delivers two to three times longer service life than any other plunger-style descale valve. The new Mega-Flo “C” plunger-style descale valve incorporates the world’s most advanced ceramic materials for reliable, continuous production with the least amount of downtime at rolling mills.

“With the latest material and design upgrades, we’re able to help customers realize a 33% reduction in the total cost of ownership for descale valves,” explained Brad Sterner, Hunt Valve’s president and CEO. “The ceramic technology we use for the Mega-Flo ‘C’ is virtually unbreakable, harder than steel, incredibly resistant to corrosion and wear, and ten times more durable than conventional valve materials.”

Additionally, the Mega-Flo “C” has an upgraded ceramic housing liner that can now be replaced in the field. This saves the downtime of sending the liner out to the manufacturer to be repaired.

State-of-the-Art Mega-Flo “C” Plunger Valve for Demanding Descaling Applications

The Mega-Flo “C” takes advantage of Hunt’s 97 years of plunger-style descale valves engineering expertise combined with the world’s toughest ceramic materials to elevate the already outstanding descale technology performance to make it the longest lasting descale valve available.

“Hunt Valve’s descale spray valve is unique due to our radial ported plunger design,” Sterner explained. “Our difference from other standard poppet valves and all other plunger designs is the time the seals are exposed to the valve water flow. It’s only exposed for one to two seconds during shifting unlike poppet seats which are directly exposed during the whole cycle – up to 60 seconds. Also, our valves feature staggered flow slots that provide gradual flow acceleration and deceleration during plunger shifting to prevent water hammer damage. This promotes safety, reduces annual operating costs and decreases unscheduled downtime in the plant.”

Mega-Flo “C” Available in a Cartridge Upgrade for Your Existing Installation

Hunt Valve’s new Mega-Flo “C” descale cartridge upgrade capability enables steel producers to extend the service life of their existing valve installation, making the cost to upgrade similar to competitors’ charges to repair the old technology. Customers with the Mega-Flo “A” or “B” plunger descale valves can upgrade their existing installations by simply replacing the old-style cartridge with a Mega-Flo “C” cartridge since it is built to drop in to the existing valve housings for a quick and easy field upgrade. It offers the benefits of the Mega-Flo “C” ceramic performance enhancements without having to replace the entire valve and results in a 40% cost savings versus purchasing a complete new valve.
