Product Description

 

Product Description

Introduction:

The Double-Acting Throttling & Shut-off Valve integrates flow regulation and positive isolation in a single unit. Its dual-disc system (main seal + throttling disc) enables precise flow control while ensuring bubble-tight shutoff, ideal for high-pressure drop, high-velocity applications in oil & gas, chemical, and power industries.

Advantage:
Dual Functionality: Combines throttling + isolation, reducing line valves.
Cavitation-Resistant: Staged flow path dissipates energy, protecting components.
High ΔP Tolerance: Handles >100bar pressure drops reliably.
Extended Service Life: Stellite-hardened sealing surfaces resist particle erosion.
Field-Maintainable: Top-entry design allows in-line maintenance.

Structural Design:

• Dual-Disc System:

  • Main Disc: Metal-to-metal or soft seal (API 598 Class VI leakage).

  • Throttling Disc: Multi-stage pressure reduction to minimize cavitation/erosion.

• Body Materials: Carbon steel (WCB), stainless steel (CF8/CF8M), or alloy steel (WC6/WC9).

• End Connections: Flanged (RF/RTJ), butt-weld (BW), or threaded (NPT/BSP).
