1. General Information

2. Applicable Standards

3. Material of Construction

All pressure-containing parts are made of Austenitic Stainless Steel ASTM A182 F316, suitable for cryogenic service down to -196°C.

Chemical Composition (ASTM A182 F316)

Parts List

Note: For cryogenic service, an extended bonnet is provided to protect the stem packing from low temperatures.

4. Dimensions (1″ – Class 900 LB RTJ Flanged)

Reference Standard: ASME B16.10 & ASME B16.5 Class 900

5. Pressure & Temperature Ratings (ASME B16.34)

For ASTM A182 F316 material, Class 900.

*For cryogenic temperatures down to -196°C, pressure rating remains at the 100°F rating (2160 psig) per ASME B16.34.*

Test Pressures (Per API 598):

• Shell Test: 4500 psig (Hydrostatic)
• Seat Test (High Pressure): 3240 psig (Hydrostatic)
• Seat Test (Low Pressure): 60 psig (Pneumatic)
• Cryogenic Test: Per BS 6364 at -196°C (Optional requirement)

6. Product Features

1. Cryogenic Design: Extended bonnet prevents ice formation on stem packing and ensures reliable operation at -196°C.
2. Floating Ball Design: Provides tight shut-off under high pressure; ball is free to move slightly to press against the downstream seat.
3. RTJ Flanged Ends: Ring-Type Joint connection ensures leak-tight sealing in high-pressure and high-temperature cycling services.
4. Fire-Safe Design: Compliant with API 607, secondary metal-to-metal seat contact in case of seat fire damage.
5. Anti-Static Device: Spring-loaded plunger dissipates static charge across ball and stem to body, preventing spark ignition.
6. Low Fugitive Emissions: Live-loaded packing system (Belleville washers) maintains constant compression on stem seals.
7. Full Bore (Optional): Unrestricted flow passage for minimal pressure drop (if specified).
8. Material Traceability: All pressure-containing parts are fully traceable to mill test reports.

7. Testing & Inspection

• Visual Examination: Per MSS SP-55
• Dimensional Check: Per ASME B16.10 & B16.5
• Hydrostatic Shell Test: 1.5 x 900LB rating at ambient temperature (as per API 598)
• Hydrostatic Seat Test: 1.1 x 900LB rating (high pressure)
• Low Pressure Pneumatic Seat Test: 60 psig air
• Cryogenic Test (Optional): Per BS 6364: at -196°C, cycling test with helium leak detection (leak rate ≤ 100 mm³/s)
• Non-Destructive Examination (Optional): PT/RT on castings, UT on forged bodies if required.

8. Aplikasi

• LNG (Liquefied Natural Gas) plants and terminals
• Air separation units (ASU)
• Cryogenic storage and transportation
• Petrochemical plants handling light hydrocarbons
• Refrigeration systems
