AUTOMAX DK-Z961Y Series is a specialized High-Pressure Electric Gate Valve designed for critical isolation in power plants and petrochemical facilities. Constructed from heavy-duty Forged Steel (F22/F91/SS), it withstands extreme pressures (up to 320 Bar) and temperatures. Powered by an Intelligent Multi-Turn Electric Actuator, this valve ensures zero-leakage shutoff and minimal pressure drop for superheated steam and boiler feedwater lines.
✅Forged Steel Body for High Integrity
Unlike cast valves, the body is machined from solid forged steel (A105, F22, F91, F316). This dense, pore-free structure provides superior strength and fatigue resistance, making it essential for small-bore high-pressure lines (DN10–DN100) where safety is non-negotiable.
✅Full Bore & Low Pressure Drop
The straight-through, full-port design allows fluids to pass with minimal turbulence and almost zero pressure loss. This high flow efficiency is critical for maintaining system performance in main steam and feedwater piping systems.
✅Stellite Hard-Faced Wedge & Seat
To resist scratching and galling under high pressure, the solid wedge and seat rings are overlay-welded with Stellite (Co-Cr-W alloy). This hardness ensures a tight Class V/VI shutoff even after repeated cycling in high-velocity steam.
✅Pressure Seal / Welded Bonnet
Designed for high-pressure ratings (Class 1500–2500), the valve typically features a Pressure Seal Bonnet or Welded Bonnet. This design utilizes the internal line pressure to reinforce the body-bonnet seal—the higher the pressure, the tighter the seal.
✅Intelligent Multi-Turn Actuation
Equipped with a smart electric actuator (as shown with LCD display). It provides precise torque monitoring, non-intrusive setup, and emergency manual operation. The Z-type drive delivers the high thrust needed to unseat the wedge under maximum differential pressure.
