Description

The API 600 Cast Steel OS&Y Gate Valve is a heavy-duty industrial valve designed for critical service in petroleum, petrochemical, and power generation industries. Engineered to meet stringent API standards, this valve features a robust cast steel body and a bolted bonnet construction. The Outside Screw and Yoke (OS&Y) design provides clear visual indication of the valve position and protects the stem threads from the flow medium, ensuring reliable operation in high-pressure and high-temperature environments.

Technical Specifications:
  • Nominal Size (NPS): 2″ – 36″ (DN50 – DN900)
  • Pressure Rating: Class 150, 300, 600, 900
  • Applicable Medium: Oil, Gas, Steam, Petrochemicals, and Corrosive Fluids (material dependent)
  • Suitable Temperature: -46°C to 538°C (-50°F to 1000°F), depending on material selection (LCB for low temp, CF8 for corrosive/high temp)

Key Product Features:
  • Heavy-Duty Construction: Built to API 600 standards, ensuring minimum wall thicknesses and robust design for severe service applications.
  • Visual Position Indication: The rising stem (OS&Y) design allows operators to instantly verify whether the valve is open or closed.
  • Versatile End Connections: Available with ANSI B16.5 flanged ends or ANSI B16.25 butt-weld ends to suit specific piping requirements.
  • Wear-Resistant Trim: Seat rings are overlaid with hard-facing materials to prevent galling and ensure a tight seal over thousands of cycles.
  • High-Pressure Capability: Rated for Class 150 through Class 900, suitable for a wide range of industrial pressures.
Applications:
Ideal for critical isolation services in oil and gas refineries, chemical plants, power stations, and high-pressure steam systems where reliability and strict adherence to API standards are required.
