2" Y-Swing Check Valve Overview

This bronze-body check valve uses a Y-pattern swing mechanism to allow full flow in one direction while preventing backflow. It fits 2-inch copper tubing with sweat connections on both ends and has an overall length of 6.375 inches. The valve operates reliably from -20 to 425 degrees Fahrenheit.

Ideal for Horizontal or Vertical Runs

Installers who need a compact check valve for potable water, hydronic heating or low-pressure steam lines up to 150 psi will find the bronze seat and seal suitable. It is not intended for systems exceeding 300 psi water pressure at 150 degrees F or for applications that require a non-bronze seating surface.

Cracking Pressure and Flow Characteristics

A low cracking pressure of .5 psi means the disc opens with minimal head loss, delivering up to 131 gallons per minute at full flow. The bronze construction resists corrosion in typical plumbing environments without adding external coatings or electronic controls.
