Bivco 1012B Lift Type Check Valve 120 PSI 3/4 Inch NPT

Bivco 1012B Lift Type Check Valve is a bronze-bodied, ¾ in (3/4") NPT, lift‑style backflow valve designed to prevent reverse flow in piping systems and rated for up to 120 psi backpressure. The 1012B family delivers bubble‑tight sealing at low differential pressures, with a large internal passage for reduced pressure drop, and uses a free‑floating seat and poppet to resist sticking. Variants exist with PTFE seats (1012B00T-0.5S) or Viton seals (1012B00V-0.5S), both featuring ¾ in female NPT connections and a Cv of 8.4. The 1012B designation is documented in Circle Valve Technologies’ BIVCO catalog as a lift‑type check valve series, with the 0 to 120 psig rating indicating the maximum backpressure in the reverse direction. This valve is suitable for lines where backflow prevention is needed in pumping or fluid-handling systems.
