Operation

N/A The RP16A allows flow from port 2 to port 1, while normally blocking flow from port 1 to port 2. The valve remains closed by bias spring until sufficient pressure is applied at pilot port 3. The cartridge has 3:1 and 4:1 optional pilot ratios, meaning that at least one-third or one-fourth (respectively) of the load pressure held at port 1 is required at port 3 to open the valve.

A sealed pilot piston option is available.

Features

N/A

  • Hardened poppet to ensure extended service life and low leakage
  • Additional reseating spring for fast and reliable closing
  • Optional sealed pilot piston
  • Higher flow rating and low pressure drop due to pilot port at 3
  • All external surfaces zinc-plated
  • Industry common cavity
