Manual Limit Switch


Hayward Flow Control announces the expansion of our 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” 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 2 or 4 limit switches for additional monitoring needs, but also available without.   Other key features of the LHB-SR include: 

  • Temperature Range 20°F (-7°C) to 200°F (93°C) 
  • Reliable Steel Spring Coil Pack with Sealed Modular Thermoplastic Housing
  • NEMA 4X Rated v Adjustable SPDT 10 Amp @ 120 VAC Switches (Open / Close position)
