Valvola a saracinesca manuale filettata, 200 WOG

Descrizione del prodotto

Unlike ball valves which close in a quarter-turn, the Valvola a saracinesca operates by lifting a rectangular gate out of the path of the fluid via a multi-turn handwheel. When fully open, the gate completely clears the passage, leaving no obstruction to flow.

Caratteristiche tecniche principali:

• Modello: GT
• Materiale del corpo: Acciaio inossidabile ASTM 316
• Pressione nominale: 200 WOG
• Gamma di dimensioni: 1/2″ ~ 2″
• Operazione: Handwheel (Multi-turn)

This design is particularly useful in applications where “Water Hammer” (shock waves caused by sudden valve closure) is a concern, as the slow-closing mechanism naturally dampens pressure spikes.

Vantaggi e benefici

• Prevents Water Hammer: The multi-turn operation ensures gradual flow reduction, protecting pipes and pumps from hydraulic shock.
• Minimal Pressure Drop: When fully open, the valve allows straight-through flow with almost zero resistance.
• Precise Control: While primarily an isolation valve, the threaded stem allows for finer adjustment of flow compared to a ball valve.
• Compact Face-to-Face: Generally narrower than globe valves, fitting into tighter linear spaces.

Campi di applicazione e ubicazioni

• General Plumbing: Main water shut-off valves for buildings.
• Viscous Fluids: Suitable for heavier oils where flow resistance must be minimized.
• Steam Supply (Low Pressure): Basic steam isolation.
• Irrigation Systems: Preventing pipe damage from pressure surges.
