Design Features

Forged Alloy Steel (F11): Suitable for high-temperature services up to 550°C, with excellent creep resistance.
API 602 Design: Compact, robust construction ideal for critical services in power generation, petrochemical, and refinery applications.
Actuator Ready: Equipped with ISO 5211 mounting pad and drive coupling, allowing direct mounting of pneumatic, electric, or hydraulic actuators without additional brackets.
Hardfaced Seats: Stellite hardfacing on disc and seat ensures long life and reliable shutoff even in erosive conditions.
Backseat Design: Provides secondary stem seal and enables repacking under pressure when valve is fully open.
폭발 방지 스템: Integral shoulder prevents stem ejection under pressure.

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.
