The BuTech FPBC4 is a compact stainless-steel ball check valve designed to prevent backflow in male or female 1/4" NPT piping systems. Constructed from 316 cold-worked stainless steel with a 17-4PH poppet, it provides reliable metal-to-metal sealing up to 15,000 psi. It requires no elastomers, making it suitable for extreme environments with temperatures ranging from 420 F to +1200 F. Lightweight and robust, it's ideal for sample lines, instrumentation panels, and high-pressure fluid systems where tight shutoff isn't necessary.
