Combination air valve figure LYNX 3F

The CSA Mod. LYNX 3F is a high-performance, single chamber triple function air valve with full bore design. It ensures air release during pipeline operation, large air discharge during filling, and air intake during draining or pipe burst, preventing vacuum and negative pressure conditions.

The aerodynamic deflector prevents premature closure of the float during filling, ensuring smooth and controlled flow.

The internal assembly is made of precision-machined solid polypropylene, offering excellent resistance and stability under pressure.

Entirely made of ductile cast iron with stainless steel internal components and an efficient air release system, the LYNX 3F stands out for its durability, performance, and easy maintenance.
