Hunt Valve has released two pump bypass control valves for high-pressure centrifugal pump systems that require a minimum flow to provide cooling for the pumps used in steel manufacturing plants when there is no system demand. With fail-safe features included, this valve technology provides increased pressure for the application while saving energy and improving efficiency.
Hunt Valve’s proportional poppet valve for descaling pump bypass applications lasts three to five times longer than traditional poppet or automatic recirculation control (ARC) valves. The proportional poppet valve eliminates water hammer in the system using a variable speed stroke profile. The proportional pump bypass valve promotes safety, reduces annual operating costs, and decreases unscheduled downtime in the plant. Hunt Valve uses electromechanical linear actuator technology in its proportional poppet valve design to eliminate the shifting reliability issues commonly associated with media pilot valves.
Hunt Valve’s Mega-Flo B Descale Valve is a fast-acting, smooth-shifting product that consistently provides high-pressure water when needed. Formed from heat-treated and corrosion-resistant stainless steel, the valve’s radial-ported plunger is precision-machined, and then plated with hard chrome.
The valve’s inherent wear-resistant design and stringent material specification help ensure a long service life for this critical component.
