  • Weight: 3.56 lb (1.62 kg)

Operation

N/A The RV12A allows flow from port 1 to port 2, while normally blocking flow in the opposite direction. The valve remains closed by bias spring until sufficient pressure is applied at port 1 at which time the poppet lifts off the seat and allows flow from port 1 to port 2.

Features

N/A

  • Hardened closing element to ensure extended service life and low leakage
  • Multiple bias spring options for back pressure application flexibility
  • Fast closing and seating
  • Low pressure drop
  • Fully guided check
  • All external surfaces zinc-plated
  • Industry common cavity
