Frequently Asked Questions
Q: What is full port?
A: The ball bore matches the pipe inner diameter, so flow is essentially unrestricted compared with a standard-port valve.
Q: What is the temperature range?
A: -60 to 450°F, wider than most stainless ball valves thanks to the PTFE packing and seats.
Q: What is the pressure rating?
A: 1000 psi WOG. See our pressure and temperature ratings chart.
Q: What are the connections?
A: Female NPT on both ends (FPT x FPT), 1/4 in. nominal.
