Technical Notes:
- Erosion Resistance: Tungsten carbide trim for high-ΔP services with sand/solid-laden fluids.
- Anti-Cavitation Design: Multi-stage cage trim reduces noise, vibration, and cavitation damage.
- Emergency Shutdown (ESD): Optional fail-safe actuators for rapid closure.
- Maintainability: Modular trim design allows in-line maintenance without valve removal.
- Accessories: Position indicator, limit switches, pressure ports for instrumentation.
Note: Final specifications subject to order requirements (PSL, materials, actuation, etc.) and manufacturer’s design. Certifications may vary by region.
