Double-eccentric butterfly valve: Lug-type
The double-eccentric butterfly valve, due to its double-offset design offers excellent tightness and minimal wear, which significantly extends its service life. With this type of butterfly valve, the disc is offset from the seat so that it moves away from the seat rather than turning around the axis when it rotates.
The double-eccentric butterfly valve type AX131 is the absolute elite among high-performance butterfly valves. Designed for high performance in critical applications, this lug-type butterfly valve is available with WCB and stainless steel bodies. The AX131 high performance butterfly valve is available in seats made from materials such as RPTFE and INCONEL, which offer excellent resistance to chemicals and high temperatures.
We offer the AX131 with hand lever and gearbox as well as with pneumatic and electric actuators and control accessories such as solenoid valve, limit switch box, positioner for versatile automation options.
