AYVAZ KV-8 Pneumatic Actuated Butterfly Valve DN25
Safe, energy-saving automated flow control that closes automatically if air supply is lost.
The AYVAZ KV-8 Pneumatic Actuated Butterfly Valve is a critical component for automatic flow management in industrial facilities. In addition, its lug-type body design allows removal from one side of the pipeline during maintenance and repair. Moreover, the single-acting spring-return actuator automatically closes the valve when the air supply is cut, therefore increasing system safety.
The GG-25 cast iron body and nickel-plated ductile iron disc offer high corrosion resistance. Furthermore, the H-EPDM seat material provides excellent sealing for hot water up to 130°C and general-purpose liquid lines. With an operating pressure range of 2–8 bar and a PN16 pressure class, the valve opens and closes in approximately 2 seconds using air pressure alone.
