OPW Loading Valves are designed to shut off the flow without causing damaging shock in the pipeline. Spring-Loaded 'Deadman Operation' – Valve must be manually held in open position and automatically closes upon release of the handle.

  • Minimize Line Shock – Variable closure rate allows operator to fine tune closure rate and prevent shock.
  • Easy Maintenance – Unique stuffing box design makes disassembly quick and easy.
  • No air traps – Air cannot become trapped in the valve, minimizing the risk of product release after closure.
  • Superior Shaft Sealing – Dual O-rings provide redundant sealing in critical area.
