AsalAra Bolted Bonnet High Pressure Ball Valve
A rugged, two or three piece bolted bonnet, trunnion mounted ball valve engineered for high pressure, critical service applications in oil & gas, petrochemical, and utility sectors.
AsalAra Bolted Bonnet High Pressure Ball Valve
A rugged, two or three piece bolted bonnet, trunnion mounted ball valve engineered for high pressure, critical service applications in oil & gas, petrochemical, and utility sectors.

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.
Why AsalAra?
The AsalAra Bolted‑Bonnet Ball Valve combines ease of maintenance, high-pressure reliability, and emission control in a versatile, serviceable design. Manufactured with global standards and regional agility, it is your trusted partner in critical flow control infrastructure.
