Product Summary

Precise Flow Regulation for Low-Pressure Systems.

The GT Series Manual Threaded Gate Valve is a classic solution for on/off control where full flow with minimal pressure drop is required. Constructed from 316 Stainless Steel and rated for 200 WOG, this valve is designed for systems where the prevention of water hammer is prioritized over rapid shut-off.

Product Description

Unlike ball valves which close in a quarter-turn, the Gate Valve 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.

Key Technical Specifications:

  • Model: GT
  • Body Material: ASTM 316 Stainless Steel
  • Pressure Rating: 200 WOG
  • Size Range: 1/2″ ~ 2″
  • Operation: 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.

Advantages & Benefits

  • 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.

Application Fields & Locations

  • 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.
