DN15-PN63-BW F310 Super High Temper Service Ball Valve

TECHNICAL DATA SHEET

PRODUCT: High-Performance Ball Valve for Super High-Temperature Service
MODEL / REFERENCE: DN15-PN63-BW F310
TYPE: Floating Ball, Trunnion Mounted (as applicable), Full Bore, Extended Bonnet, Fire-Safe Design

1.0 PRODUCT DESCRIPTION & APPLICATION
A heavy-duty, high-pressure ball valve specifically engineered for severe super high-temperature applications exceeding standard industrial ranges. Fabricated from ASTM F310 (25Cr-20Ni) heat-resistant alloy steel, this valve offers exceptional strength, resistance to oxidation, and resistance to creep under sustained high temperatures. The extended bonnet isolates standard packing from the process heat, while advanced sealing materials ensure reliable, long-term performance in furnaces, heaters, high-temperature process lines, steam systems, and thermal oil applications.

2.0 DESIGN & STANDARDS

• Design & Pressure Rating: ASME B16.34, Class 400 (aligned with PN63 rating)
• End Connection: BW (Butt Weld) ends per ASME B16.25
• Face-to-Face: ASME B16.10
• Fire Safe Design: API 607 / API 6FA / ISO 10497 (Standard)
• Anti-Static: API 608 / ISO 17292 (Standard)
• Blow-Out Proof Stem: As per API 608

3.0 GENERAL SPECIFICATIONS

4.0 PRESSURE-TEMPERATURE RATINGS

• The valve body and critical components are rated for PN63 (63 bar) in accordance with ASME B16.34 for Class 400.
• Maximum Allowable Working Pressure decreases as temperature increases. Consult the detailed manufacturer’s P-T rating chart for the specific F310 material and seal combination at target temperatures (e.g., 800°C).

5.0 MATERIALS OF CONSTRUCTION

6.0 KEY DESIGN FEATURES FOR HIGH TEMPERATURE

• Extended Bonnet: Creates a thermal barrier, protecting stem packing and actuator from extreme process heat.
• Heat-Resistant Alloy (F310): Superior to standard 304/316 alloys in high-temperature strength and oxidation resistance.
• Fire-Safe Design: In event of fire, metal-to-metal secondary seals provide emergency shut-off (per API 607).
• Anti-Static Device: Ensures continuity between ball, stem, and body to prevent static charge buildup.
• Blow-Out Proof Stem: Stem is retained under full pressure, even with bonnet removed.

7.0 TESTING & INSPECTION

• Shell & Seat Pressure Test: Per API 598 / ISO 5208 at 1.5 x PN and 1.1 x PN respectively.
• Fire Test: Certified per API 607 / ISO 10497.
• High-Pressure Gas Test: Optional for seat leakage verification.
• Material Verification: Positive Material Identification (PMI) on critical components.
• Documentation: Mill Test Certificates (MTC 3.1) for body material. Full test reports and certification packages available.

8.0 END PREPARATION & DIMENSIONS

• Butt Weld Ends: Prepared per ASME B16.25 with controlled inside diameter and bevel for welding.
• Weight & Dimensions: Provided on detailed dimensional drawing (Dimensional Data Sheet available upon request).

9.0 OPTIONS & ACCESSORIES

• Actuation: Pneumatic (double-acting/spring-return), Electric, Hydraulic actuators with high-temp linkage kits.
• Gear Operator (essential for high-pressure manual operation)
• Locking Device / Limit Switch
• Steam Jacketed Body
• Drain / Vent Ports
• Special Seal Materials for specific high-temperature media (e.g., thermal oil, synthetic fluids)
• Stem Extension for insulated lines

10.0 NOTES & WARNINGS

• CRITICAL: Seat and packing material selection must be explicitly confirmed for the specific process temperature and media. Standard PTFE seats are not suitable for super high-temperature service.
• The extended bonnet length is calculated based on the specified operating temperature and required insulation thickness.
• Proper warm-up/cool-down procedures and controlled cycling are recommended for extreme temperature services to maximize valve life.
• All specifications are indicative and subject to final engineering review based on the complete customer datasheet (process fluid, exact temperature, pressure, cycle frequency).
