Product Overview

The Forged Steel Gate Valve is a high-performance solution designed for extreme pressure and temperature applications in oil and gas, petrochemical, and power generation industries. Manufactured through precision forging, it offers superior strength, durability, and leak-tight sealing, making it ideal for critical isolation tasks in harsh environments. This valve is strictly for on/off service and not suitable for throttling.

Applications

Oil & Gas: Wellhead isolation, pipeline shut-off, and refinery applications.
Petrochemical: High-pressure fluid control in chemical reactors and distillation units.
Power Generation: Steam isolation in turbines and boiler feedwater systems.
Marine: Offshore platform and shipboard piping systems.

Key Features

Forged Construction

  • Material Integrity: Forged A105, F22, or F316 steel for enhanced grain structure and impact resistance.
  • Pressure Capacity: ANSI Class 1500–2500 (PN260–PN420).
  • Temperature Range: -29°C to 593°C (-20°F to 1100°F).

Gate Design

  • Wedge Type: Flexible or solid wedge for zero leakage (ANSI Class VI).
  • Fire-Safe: API 607 certified with secondary metal-to-metal sealing.
  • Stem Design: Rising stem (OS&Y) or non-rising stem (NRS) options.

Sealing & Operation

  • Seat Materials: Stellite 6 overlay, 13% Cr stainless steel.
  • Stem Packing: Graphite or PTFE for high-temperature reliability.
  • Operation: Manual handwheel, gear operator, or actuator compatibility.
