Pressure reducing valves are devices which, when installed on water systems, reduce and stabilize the pressure of the water entering from the water supply main. This pressure, in general, is too high and variable for domestic systems to operate correctly. The 535H series pressure reducing valves, ideal for residential and commercial applications, feature a dial indicator with direct readout allowing easy pressure pre-adjustment. After installation, the valve will control at the pre-adjusted pressure setting.The valve is constructed of DZR low-lead forged brass and incorporates a unique noise reducing and high flow seat design, is easily serviced with a replaceable cartridge and has an integral stainless steel filter (35 mesh), suitable for water systems that may contain sediment and debris.

  • Unique noise reducing pressure balanced cartridge
  • Low friction, anti-scale moving parts
  • High flow seat design
  • Dial indicator with direct readout
  • Adjustment locking screw
  • Without outlet pressure gauge
  • 15 - 90 psi pressure setting range
  • 45 psi factory setting
