Value Brand 32H978 3" FNPT Brass Ball Valve Inline

SKU CH-R9SD-SCWDR

A 3-inch brass ball valve with FNPT connections, full port design and 600 psi pressure rating

  • Full-port design maximises flow through the 3 in brass body
  • Locking lever handle secures valve position for safe operation
  • Blowout-proof stem prevents stem ejection under pressure
  • PTFE seats and seals resist corrosion across a wide temperature range
  • Rated 600 psi WOG and 150 psi WSP for demanding applications

3-inch FNPT brass ball valve

This full-port inline valve is built from brass with PTFE seats and seals, rated for 600 psi WOG and 150 psi WSP. It suits plumbing and industrial lines that need a straight-through shut-off in a 3-inch pipe size. The locking lever handle prevents accidental operation.

Pressure and temperature limits

The valve handles water, oil and gas up to 600 psi and saturated steam up to 150 psi. Its temperature range runs from 0 to 400 degrees F, so it is not suited for cryogenic fluids or superheated steam above the stated limit. The blowout-proof stem adds safety under pressure.

Replaces standard-port or non-locking valves

Swapping in this full-port model removes the flow restriction of a reduced-bore valve and adds a locking lever for secure isolation. The upgrade is worth it when maximum flow capacity and lockout capability are required on 3-inch FNPT lines. California Proposition 65 warnings apply.

Questions about this item

Should I choose this 3-inch FNPT brass ball valve or a different size for my piping?

Select the 3-inch version when your pipe size is exactly 3 inches; the FNPT threads and full-port design match that diameter directly.

What does the 600 psi WOG rating mean once the valve is installed in my system?

The valve will hold up to 600 psi water, oil or gas pressure at ambient temperature without leaking.

How does the FNPT connection type limit what I can thread this valve onto?

FNPT provides female National Pipe Taper threads on both ends, so you need male NPT fittings or pipe nipples to make the joint.
