The Conbraco (Apollo) 36C-105-01 is a compact, direct‑acting 1" pressure reducing valve engineered to protect water distribution systems by automatically controlling high inlet pressure and stabilizing downstream pressure. Factory preset to 50 psi and field adjustable, this model combines durable materials and serviceable construction for long-term reliability in irrigation, plumbing, and commercial water systems.

  • Adjustable outlet pressure: Factory preset 50 psi; adjustable 25–75 psi (high setting options up to 125 psi available).
  • Rugged construction: Bronze body (ASTM B584) with stainless steel internal strainer and stainless adjusting screw for corrosion resistance.
  • Reliable softgoods: EPDM seat and disc with FDA‑grade nitrile O‑rings for consistent sealing and compatibility with potable and non‑potable water.
  • Performance: Handles maximum supply pressures up to 400 psi and standard temperature range 33°F to 180°F.
  • Serviceability: Sealed spring cage, bottom cleanout access to seat disc and strainer, and easy inline servicing without full removal.
  • Vault & field ready: Sealed spring cage for vault installation, built‑in thermal expansion bypass, and multiple connection options including union x NPT.

Dimensions and installation notes: nominal 1" size with a compact inlet‑to‑outlet footprint suitable for tight piping layouts. Typical flow capability for the 1" assembly meets many irrigation and small commercial demands; select sizing based on system flow and headloss requirements. Documents available include the installation/operation manual and a full submittal/specification sheet for engineering review. For maintenance: inspect and clean the stainless strainer periodically and verify outlet set pressure after major system changes or thermal events.
