  1. Applicable Design Standards
  • Valve Design & Manufacture: BS 1873 / API 623 / ASME B16.34
  • Face-to-Face Dimensions: ASME B16.10 / EN 558 (Y pattern specific)
  • Flange Dimensions: ASME B16.5 (Class 150) / EN 1092-1 (PN16)
  • Pressure-Temperature Rating: ASME B16.34 / EN 1092-1
  • Inspection & Testing: API 598 / EN 12266
  • Bellows Design: ISO 15761 / BS 6364
  • Actuator Mounting: ISO 5211 / VDI/VDE 3845

  • Control Valve Testing: IEC 60534 / FCI 70-2 (for modulating service)
  1. Product Features
  1. Y Pattern (Oblique) Design: Angled seat and stem design significantly reduces flow resistance (lower pressure drop) compared to standard globe valves, ideal for applications requiring continuous flow with throttling capability.
  2. Bellows Seal: Fully welded stainless steel bellows provides a hermetic seal, eliminating fugitive emissions and ensuring zero stem leakage—critical for steam, thermal oil, and hazardous media applications.
  3. Pneumatic Actuation: Enables remote, automated operation for on-off or modulating control, improving system efficiency and safety.
  4. Fail-Safe Operation (Spring Return): Spring-return actuators ensure valve returns to a safe position (fail-open or fail-closed) upon loss of air supply, providing critical safety protection.
  5. Raised Face Flanged Ends: Standard RF flanges ensure reliable, leak-free connections compatible with ASME or EN piping systems.
  6. PN16 Pressure Rating: Suitable for low to medium pressure applications commonly found in steam distribution, HVAC, and industrial processing.
  7. Hard-Faced Trim (Optional): Stellite hard-facing on seat and disc surfaces provides excellent wear resistance and tight shut-off for demanding services.
  8. ISO 5211 Mounting Pad: Standardized mounting interface ensures easy actuator installation, alignment, and maintenance.
  9. Accessories Ready: Designed to accommodate solenoid valves, positioners, limit switches, and air filter regulators for complete automation packages.

Remarks:

  • Material Selection: Specify body material based on media:
    • WCB: Water, oil, steam, non-corrosive services
    • CF8 (304): Mildly corrosive services
    • CF8M (316): Highly corrosive services, chlorides, and marine applications
  • Actuator Selection: Specify actuation mode:
    • Spring Return (Fail Closed): Air to open, spring to close
    • Spring Return (Fail Open): Air to close, spring to open
    • Double Acting: No fail-safe, requires air supply to both open and close
  • Control Type: Specify whether the valve is for on-off service (solenoid valve control) or modulating service (positioner with 4–20 mA signal).
  • لوازم جانبی: Specify required accessories for complete automation:
    • Solenoid valve (voltage: 24VDC, 110VAC, 220VAC, etc.)
    • Positioner (analog 4–20 mA / digital / HART / Profibus)
