ARI-ZESA® 22.012 Wafer Tip Kelebek Vana DN50 / PN16

ARI-ZESA® 22.012 Wafer Type Butterfly Valve DN50 / PN16: High Performance and Reliable Flow Control

The ARI-ZESA® 22.012 Wafer-Type Butterfly Valve, offered with the assurance of ORFA Industrial Products Industry and Trade Inc., is an indispensable flow control element that offers reliability, performance, and long life in industrial systems. This valve stands out with its compact design, superior sealing performance, and maintenance-free design.

It is a versatile solution for use in medium-sized lines with its DN50 (Nominal Diameter 50 mm / 2 inches) size and PN16 (16 bar) pressure class, providing perfect sealing in both directions and easy integration into automation.

What is ARI-ZESA® 22.012 Wafer Type Butterfly Valve?

The ARI-ZESA® 22.012 operates on the basic principle of a butterfly valve. Its internal disc (clapper) rotates 90 degrees around a vertical shaft, completely opening or closing the flow. Its wafer-type design allows it to be sandwiched between two flanges, saving space.
