Nibco T-FP600A-LF Ball Valve - Lead-Free* Brass, Two-Piece, Full Port, NPT x NPT

Threaded both ends, female NPT (FIPT) x female NPT. It screws straight onto male NPT pipe nipples or threaded steel, brass, or CPVC male adapters with no soldering and no extra adapter. Sizes run 1/4 inch through 4 inch, so you match the valve to the nominal pipe size you are tying into. Because the ends are threaded rather than solder, you can install it in an occupied space without an open flame and take it back out later without cutting pipe.

Yes, within the stated approvals. The T-FP600A-LF carries CSA ANSI Z21.15 / CSA 9.1 across 1/4 to 4 inch, CSA ASME B16.33 at 125 psig maximum and B16.44 at 5 psig maximum, plus UL 842 (YRPV) gas shutoff at 250 psi and UL 125 (YSDT) LP-gas shutoff at 250 psi. Note the fuel gas pressure ceilings are the governing numbers on a gas line, not the 600 psi water rating. It is also UL 1477 listed for compressed gas and UL 842 (YRBX) for flammable liquid shutoff, both at 250 psi.

It does change with size, and this catches people out on larger lines. The 1/4 inch through 2 inch valves are rated 600 psi / 41.4 bar non-shock cold working pressure. The 2-1/2, 3 and 4 inch valves drop to 400 psi / 27.6 bar non-shock cold working pressure. If you are speccing a 3 inch valve off the 600 psi headline number, the real figure on the drawing is 400.

Yes, in the smaller sizes. The valve is listed under UL Subject 258 (VQGU) for trim and drain valves in 1/4 inch through 2 inch, and it is FM 1140 approved at 175 wwp over that same 1/4 to 2 inch range. Above 2 inch those two approvals do not apply, so for a 2-1/2 inch or larger fire protection application this is not the valve to write into the submittal.

Eleven sizes, 1/4 inch (NL998X4), 3/8 inch (NL998X5), 1/2 inch (NL998X6), 3/4 inch (NL998X8), 1 inch (NL998XA), 1-1/4 inch (NL998XB), 1-1/2 inch (NL998XC), 2 inch (NL998XD), 2-1/2 inch (NL998XE), 3 inch (NL998XF) and 4 inch (NL998XH). All are the same two-piece full port lead-free brass body with female NPT ends, so you can standardize one valve across a building and just change size. Order by the NL998X number for the size you need.

A standard carbon steel lever handle is included on the valve as supplied. Operation is quarter turn, 90 degrees open to closed, so you need roughly a quarter circle of clear swing space beside the pipe for the lever. On tight mechanical rooms or inside a chase, check that clearance before you set the valve orientation, because the lever is what determines the space you need, not the valve body.

A two-piece body like the T-FP600A-LF splits into a main body and an end cap, which is how it achieves a full port bore in a compact threaded valve. A one-piece body is a single casting and is typically reduced port. Neither is a field-serviceable design in the way a three-piece union valve is, so if your application needs the valve broken out for cleaning or the trim replaced without cutting pipe, a three-piece union-end valve is the right choice instead. For general isolation on water, gas, or compressed air where you replace rather than rebuild, the two-piece is the standard commercial answer.

No. The T-FP600A-LF uses a blowout-proof stem, which is inserted from inside the body so line pressure seats it rather than pushing it out. That is what makes it acceptable for gas and compressed gas service, where a stem failure vents the line. It also means you can pull the handle nut to reclock a handle or swap a lever without the stem lifting under pressure.
