AsalAra Bolted Bonnet High Pressure Ball Valve
- Bolted Bonnet Ball Valve
Designed for maximum reliability, the AsalAra Bolted‑Bonnet Ball Valve features trunnion‑mounting and a bolted body assembly that ensures exceptional sealing, ease of maintenance, and high structural integrity under extreme pressures (up to Class 2500). Independent top and bottom seats (double block & bleed) provide reliable isolation. Advanced materials and packing options resist corrosion, temperature extremes, and fugitive emissions. Ideal for upstream, midstream, offshore, and process-critical service where performance and uptime are paramount.
