Hunt Valve’s Pump Bypass Control Valves Unlock Potential Energy, Efficiency and Cost Savings

Many steel mills have implemented continuous bypass flow as a fail-safe method of ensuring that pumps don’t overheat or get damaged. While this method is fail-safe, it’s not ideal. Why? Because it wastes a ton of energy. To help steel producers save energy and improve efficiency, Hunt Valve has released pump bypass control valves for high-pressure centrifugal pump systems that require minimum flow to PumpBypassControl.pngprovide cooling for the pumps when there is no system demand.

With built-in fail-safe features, Hunt Valve’s pump bypass control valves deliver minimum flow for pump cooling when needed—providing the capability to direct 100% of the flow to the descale header when required. This method allows steel producers to direct higher flows and pressures to improve the descale efficiency and product surface quality or shut down a pump by eliminating continuous bypass flow from multiple pumps, resulting in significant energy cost savings.

Check out Hunt Valve’s versatile valve products for pump bypass control:

1.    Proportional Ceramic Pump Bypass (Minimum Flow) Valve
The proportional poppet valve for descaling pump bypass applications lasts three to five times longer than traditional poppet or automcontrol-valve2_200.jpgatic recirculation control (ARC) valves. The valve’s ceramic technology optimizes the component’s useful service life while the electromechanical actuation eliminates pilot shifting.

The proportional poppet valve eliminates water hammer in the system using a variable speed stroke profile—a technology that no other company is using for descale valves in the steel industry. In addition, Hunt Valve is the only company using electromechanical linear actuator technology in its proportional poppet valve design to eliminate the shifting reliability issues commonly associated with media pilot valves.

2.    Hollow Spool Pump Bypass (Minimum Flow) Valve
Built with innovative design technology and quality engineering, the Mega-Flo B Descale Valve is a fast-acting, smooth-shifting proHunt-Valve-Descale-Valve-Mega-Flow-B_2.jpgduct that consistently provides high-pressure water when needed. Constructed with 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. In fact, the valve’s smooth-shift operation helps prolong the life of all components within the descaling system.
