Check Valves
Pneu-Hydro’s bar stock check valves seal bubble-tight, even without back-pressure. When open, they provide a smooth flow-path with minimum resistance. The poppet is spring-loaded for positive operation regardless of orientation. Back pressure and spring loads are borne by a metal stop rather than the soft O-ring seal. This ensures long seal life and minimum maintenance. Operation is smooth and chatter-free.
These check valves are constructed of 316 stainless steel for strength and corrosion resistance and meet the requirements of NACE MRO175. Because of their bar stock design, the valves can be easily made from a variety of materials to satisfy the needs of your operating environment. Buna-N or Viton seals are available from stock, and other O-ring materials can be provided.
