AYVAZ KV-17 Pneumatic Butterfly Valve PN16 DN250
Compact, corrosion-resistant shutoff with automatic failsafe closure.
AYVAZ KV-17 Pneumatic Butterfly Valve PN16 DN250 provides a critical safety solution for emergency shutdown in industrial facilities. In addition, its wafer-type compact body occupies minimal space between flanges, which simplifies installation. Moreover, the single-acting spring-return mechanism closes automatically when energy is lost, therefore protecting the system.
The GGG-40.3 ductile iron body withstands PN16 pressure ratings, while the aluminium bronze disc resists seawater and chemical solutions. Furthermore, the AISI 420 stainless steel stem and NBR gasket deliver stable performance from -20°C to +80°C. Consequently, an air supply of 2–8 bar produces quiet, vibration-free operation.
