Structural Features:
- Trunnion-mounted design — ball is supported by upper and lower trunnions, reducing operating torque at high pressure
- Blow-out proof stem — stem segment designed to prevent ejection under internal pressure
- Anti-static device — spring-loaded stem-to-ball contact ensures static discharge
- Double piston effect relief — cavity pressure auto-relieved to downstream
Functional Characteristics:
- Quarter-turn operation (90°) — full open to full close
- Bidirectional shut-off capability
- Emergency seat sealing — downstream seat energizes automatically under overpressure
- Low torque operation due to trunnion bearing support
Applicable Industries:
- Oil & Gas Upstream / Midstream
- Refining & Petrochemical
- LNG / Cryogenic Service
- Power Generation
- Water Treatment (high-pressure)
Installation Requirements:
- Install in any orientation (horizontal, vertical, inverted)
- Ensure adequate pipe support to avoid mechanical load on valve body
- Follow API 6D torque specifications for flange bolting
Notes:
- Part suffix -00131 denotes specific trim, size, and connection variant per Cameron internal ordering system
- Always verify exact configuration against Cameron datasheet using full part number
