Ball valves

Product catalog summary

Certifications and Approvals
The document details certifications and approvals for ball valves, including DNV Type Approval, TÜV A352.09, TA-Luft ISO 15848, and compliance with directives 2014/68/EU and 2014/34/EU. Standards such as BS 6364 for cryogenic service and EN 161 for automatic shut-off valves are also mentioned. The valves are certified for fire safety, cryogenic testing, and final inspection.

Design and Specifications
The ball valves are designed according to standards like BS5351, ANSI B16.34, and ISO 17292. They feature ISO 5211 top flanges, fire-safe construction, and pressure testing as per API 598 and ISO 5208. Configurations include floating ball, guided ball, full trunnion, and split body designs, with options for full and reduced bore, bidirectional flow, and both soft and metal seats.

Materials and Construction
Materials used include A216 WCC, A351 CF8M for the body, and AISI 316 for the stem. Seats are available in PTFE and other composites. The design includes anti-blowout and anti-static stems, auto-adjustable packing, and maintenance-free features.

Dimensions and Weight
Detailed dimensions and weights are provided for various valve sizes (NPS) and pressure classes (150, 300, 600), including measurements for full bore and reduced bore configurations.

Applications and Industry Use
The valves are approved for use by companies like Repsol-YPF, Qatar Petroleum, and China Petroleum. They are suitable for food processing, pharmaceutical industries, and gas distribution with pressures up to 16 bar.

Additional Features
Features include double block and bleed, low emission design, and self-cavity pressure relief. They handle cryogenic temperatures and are certified for ISO 14001 and ISO 9001.

Specifications
Specifications for ANSI ball valves cover classes (150, 300, 600, 900, 1500, 2500) and sizes (1/4” to 24”). Materials include A105N/LF2, A182 F316 for the body, A182 F316/LF2+ENP for the ball, and A182 F51 for the stem. Seat materials include PTFE, PTFE+FG, PTFE+CG, and DEVLON. Stem O-rings are Viton®, with graphite packing and seat seals.

Dimensions
Dimensions are detailed for different NPS sizes and pressure classes, including RF, RTJ, BW, and SW connections, with tables for full bore (FB) and reduced bore (RB) configurations.

Torque and Pressure Ratings
Breakaway torque values are specified for different valve classes and sizes, with notes on potential increases after inactivity. Maximum allowable stem torque (MAST) is detailed for various ISO 5211 top flange sizes.

Performance and Limitations
Pressure-temperature limitations and Kv values for flow rates across different NPS sizes are outlined. Torque values may vary with different seat materials.

Ordering Information
Instructions for ordering PEKOS ball valves highlight available configurations, including heating jackets, cryogenic, and metal-to-metal options.

Additional Notes
PEKOS reserves the right to amend specifications without prior notice, and published data may change.
