The ZH series automatic recycling control valve was developed for high pressure centrifugal pump protection. Popular applications include boiler feed water, petroleum fluids, and steel mill hot strip descale water. The ZH provides economical and reliable protection against low and reverse flow. By combining sensing element, bypass flow control, bypass pressure reduction, pulsation dampener and bypass line check valve, the valve eliminates at least seven components necessary with a conventional system. The valve operates without air or electric power and is easily installed with three connections.
