  • Size & Pressure: 1" inlet/outlet; rated for 175 psi working pressure.
  • Included valves: Union ball valve shutoffs for easy isolation and servicing.
  • Strainer: Bronze Y-type strainer included to reduce particulates and protect internal checks.
  • Material: Bronze construction for corrosion resistance in irrigation and commercial plumbing applications.
  • Application: Designed to provide reduced pressure protection where high-hazard backflow prevention is required.

This assembly is ideal for irrigation, landscape, and other non-potable water systems where code-compliant reduced pressure protection is required. The union ball valves and Y-strainer make routine testing and maintenance faster, and the bronze body helps ensure long-term reliability in outdoor and mechanical-room installations.
