Zoro Select 6AJY9 Spring Check Valve

The Zoro Select 6AJY9 is a bronze inline spring check valve built for general-purpose plumbing installations. It fits 1 inch sweat connections and operates in horizontal or vertical orientations. The 304 stainless steel spring resists corrosion across typical water systems.

Sweat connection limits and pressure ratings

Sweat joints demand clean copper tube and proper soldering technique to hold pressure. The valve handles up to 200 psi water pressure at a maximum temperature of 250 degrees F. Steam service is not rated, so do not install on steam lines.

3.5 psi cracking pressure governs flow initiation

Flow begins only when inlet pressure exceeds 3.5 psi, delivering up to 22 gpm once open. Systems with very low head pressure may not overcome this threshold. Verify that your circuit pressure exceeds the cracking value before specifying this valve.

Questions about this item

What does the 22 gpm flow rating mean for a residential plumbing system?

It indicates the valve can pass up to 22 gallons per minute of water at the rated pressure, which is typical for 1-inch supply lines in general-purpose installations.

How does the 3.5 psi cracking pressure affect operation in a gravity-fed system?

The valve requires at least 3.5 psi of inlet pressure to open, so it may not function reliably in low-head gravity systems unless sufficient elevation or pump pressure is present.

What are the practical limits of the sweat-by-sweat connection on 1-inch copper tubing?

The sweat ends are made for 1-inch copper tube and must be soldered in place; the bronze body handles up to 200 psi water pressure and 250 °F temperature within those limits.
