AYVAZ KV-17 Wafer Pneumatic Butterfly Valve PN16 DN125

Reliable fail-safe flow control for critical industrial automation systems.

AYVAZ KV-17 Pneumatic Butterfly Valve is engineered for reliable fluid management in industrial automation systems. In addition, its DN125 nominal diameter and PN16 pressure class make it a core component for liquid and gas control in critical facilities. Moreover, the spring-return fail-safe mechanism performs automatic closure during energy loss, therefore keeping system safety at maximum level.

The compact wafer body design takes minimum space between pipeline flanges. Furthermore, the GGG-40.3 ductile iron body increases durability, while the aluminium bronze disc delivers long service life in challenging media such as seawater and chemicals thanks to its corrosion resistance. The AISI 420 stainless steel stem and NBR seal rated to 90 °C support stable operation, and the ISO 5211 mounting pad allows precise control with a 2-8 bar air supply.
