• The disc profile is aerodynamically optimized to reduce pressure loss.
• High quality o-rings from reliable suppliers enable tight sealing.
• A soft seat reduces backflow leakage and enables quiet operation.
• Robust single spring design lasts over one million cycles minimizing failure risk.
• Low maintenance for an extended service lifetime.
• Suitable for vertical or horizontal installation orientations.
• Effective water hammer protection.
• Body marked with flow direction arrow for proper application.
• The stainless steel shaft composition ensures both strength and corrosion resistance.
• All units hydrostatically tested to 1.1 x seat rating and 1.5 x shell rating per EN 12266-1.

The Lug Butterfly Valve is a highly efficient solution for industrial fluid control, designed for secure flange connections and easy maintenance. Constructed from ductile iron or other durable body materials, it ensures long-lasting operation even in demanding environments. The stainless steel seat material enhances sealing performance, reducing leakage risks.

For automated control, the Lug Butterfly Valve with Pneumatic Actuator integrates a pneumatic actuator, including double acting actuators, enabling precise open and close functionality. The actuator, made from anodized aluminum, provides durability while ensuring smooth operation. The lug style design enhances stability and allows for easy installation and removal without disrupting the pipeline system.
