Accurate Control – 90-degree rotation from Full Off to Full On.
Bolted Bonnet – Safety Bonnet is bolted into the body, it avoids the well-known risks of corrosion, cross-threading, galling of threaded type connection in production environments.
Extended Mean Time Between Service – Robust design and liberal application of hardened materials, efficient flow-geometry means the valves offer maximum production potential and minimum service requirements.
Easy Maintenance – Repair parts can be installed in the field without removing the valve from the line.
