- ABO 900 butterfly valves have a groove and tongue design, with double sided profiles of the liner ensuring proper alignment of the sleeve in the outer body, and a forming lobe for securing liner stability.
- The valve design encompasses a three stage sealing system that yields perfect tightness.
- Thanks to its extended neck, the ABO 900 butterfly valve provides for full thermal isolation of the actuator from the media thermal impact. Further, upward movement of the stem is avoided by a security grub screw in the body neck (blow-out proof).
- Thanks to a 2-piece stem system, and a highly profiled disc, the ABO Series 900 achieve high Cv (Kv) values and lower pressure drops. This simple but important feature ensure that ABO Series 900 butterfly valves are much more environmentally friendly compared to regular types of butterfly valves, as they consume less energy while being operated in the system.
