  • Bronze body resists corrosion for long service life
  • 26 gpm flow capacity handles demanding supply lines
  • 3 psi cracking pressure opens with minimal head loss
  • 304 stainless spring maintains reliable closure cycles
  • 250 °F temperature rating suits hot-water systems

Zoro Select 1-1/2" Bronze Check Valve

This inline spring check valve uses a bronze body with sweat-to-sweat connections for 1-1/2 inch copper piping. It suits general-purpose plumbing where backflow prevention is required in horizontal or vertical runs.

Sustained flow and pressure limits

The valve handles continuous water pressure up to 200 psi and temperatures up to 250 degrees Fahrenheit. A 304 stainless steel spring maintains a consistent 4.3 psi cracking pressure during extended operation.

Sweat connection practical limits

Sweat joints demand clean copper and proper soldering technique to seal reliably at the rated 200 psi. The 4 15/16 inch length and 2 21/64 inch width define the space needed inside the pipe run.

Highlights

  • Bronze body resists corrosion for long service life
  • 26 gpm flow capacity handles demanding supply lines
  • 3 psi cracking pressure opens with minimal head loss
  • 304 stainless spring maintains reliable closure cycles

Questions about this item

How much heat can the 1-1/2" bronze valve handle before the 4.3 psi spring check loses reliability?

The bronze body and 304 stainless steel spring are rated for continuous service up to 250 °F, so the 4.3 psi cracking pressure remains consistent throughout that temperature range.

What pipe preparation do I need before sweating this 1-1/2" valve into my copper lines?

You need clean 1-1/2" copper tube, flux, lead-free solder and a torch; the sweat-by-sweat ends accept standard copper tubing of that nominal size.

Will the 26 gpm flow rating cause excessive pressure drop on my older 1/2 hp circulator pump?

At 26 gpm the valve is designed for low restriction; typical residential circulators operate well below that flow, so pressure drop stays minimal.
