Hayward Flow Control has expanded its patent-pending LHB Series Manual Limit Switch line to now include a Spring Return “Dead Man Handle” design for those critical applications requiring compliance to safety standards or plant specifications where the valve must return to a closed position after operation. The LHB-SR ensures that the handle will always return to its original starting position as designated. As with the new LHB, the LHB-SR fits all sizes of Hayward TB Series Ball Valves and through 8-inch BY Series Butterfly Valves. Available in two sizes, LHB1-SR and LHB2-SR, the LHB-SR features a robust corrosion resistant GFPP housing with FPM seals and a 304 stainless steel stem. Additionally, the LHB-SR comes with either two or four limit switches for additional monitoring needs, but also available without.
