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.
