Sioux Chief 648XG3XRV 3/4" PEX x 3/4" PEX No-Lead Brass Ball Valve with Expansion Relief

The Sioux Chief 648XG3XRV is a 3/4" PEX x 3/4" PEX ball valve built for rough-in plumbing shutoff applications, connecting to PEX tubing with F1807 crimp fittings on both ends. Constructed of NL/DZR brass for corrosion resistance and lead-free potable water service, it features a chrome-plated ball and a blowout-proof stem for long-term, reliable operation. This valve is ANSI/NSF 61 listed and includes a built-in expansion relief feature to help manage thermal expansion within closed PEX systems, a common requirement on water heater supply lines.

Key Features

  • Trade Size: 3/4" PEX x 3/4" PEX connections size this valve for direct tie-in to standard 3/4" PEX tubing runs.
  • Durable Construction: NL/DZR (dezincification-resistant) brass body resists corrosion and dezincification in potable water lines.
  • F1807 Crimp Connections: Both ends accept F1807 PEX crimp fittings for a secure, code-recognized crimp joint.
  • Chrome-Plated Ball: Smooth, corrosion-resistant chrome-plated ball delivers consistent quarter-turn shutoff.
  • Blowout-Proof Stem: Stem design helps prevent stem ejection under line pressure for safer field operation.
  • Expansion Relief: Built-in expansion relief feature helps relieve excess pressure caused by thermal expansion in the PEX line.
  • No-Lead Compliant: Manufactured to No-Lead (NL) standards for potable water applications.

Sioux Chief 648XG3XRV – Frequently Asked Questions

1) What does the expansion relief on this PEX ball valve actually do?
The 648XG3XRV carries a built-in expansion relief feature that bleeds off excess pressure from thermal expansion in a closed PEX system. That is why this version gets specified on water heater supply lines, where heating water in a line with a check valve or backflow preventer upstream has nowhere to go. If your system already has a thermal expansion tank or a separate relief device, you can run the plain ball valve instead.
2) Is this valve approved for potable water?
It is ANSI/NSF 61 listed and built from no-lead, dezincification-resistant brass, which is what inspectors look for on potable supply piping. The ball is chrome plated and the stem is blowout proof, so it holds up in domestic water service rather than just mechanical or hydronic use.
3) Can I use this as the shutoff ahead of a water heater on PEX?
That is the main use case for the relief-valve version. It gives you a quarter-turn shutoff on the 3/4 inch PEX supply plus relief for the pressure rise when the heater fires in a closed system. Both ends crimp to F1807, so you tie it in with the same rings and tool you use for the rest of the rough-in.
4) Does the brass on this valve hold up in aggressive water?
The body is NL/DZR brass, meaning it is alloyed to resist dezincification, the zinc leaching that pits ordinary yellow brass in high-chloride or low-pH water and eventually causes pinhole leaks. Combined with the chrome-plated ball, that makes it suited to long-term potable service rather than temporary use.
5) How many Sioux Chief 648XG3XRV valves come in a case?
Six each per case. Useful if you are stocking a truck or rough-in package for multiple units, since each dwelling typically needs only one at the heater.
