7. Design Features

  1. Forged Alloy Steel (F11): Suitable for high-temperature services up to 550°C, with excellent creep resistance.

  2. API 602 Design: Compact, robust construction ideal for critical services in power generation, petrochemical, and refinery applications.

  3. Actuator Ready: Equipped with ISO 5211 mounting pad and drive coupling, allowing direct mounting of pneumatic, electric, or hydraulic actuators without additional brackets.

  4. Hardfaced Seats: Stellite hardfacing on disc and seat ensures long life and reliable shutoff even in erosive conditions.

  5. Backseat Design: Provides secondary stem seal and enables repacking under pressure when valve is fully open.

  6. Anti-Blowout Stem: Integral shoulder prevents stem ejection under pressure.

8. Inspection & Testing

  • Material Test Certificates: EN 10204 3.1 available.

  • Hydrostatic Testing: 100% tested per API 598.

  • NACE Compliance: Optional if required for sour service (NACE MR0175/ISO 15156).

  • Radiography / PMI: Available upon request.

Remarks:

  • F11 material is normalized and tempered for optimal mechanical properties.

  • For actuator sizing, valve torque data can be provided separately.

  • Other end connections (socket weld, threaded) are available on request.

This data sheet can be customized further based on specific actuator requirements and mounting details.
