AYVAZ KV-4 Pneumatic Actuated Butterfly Valve DN50
Double-acting pneumatic actuation delivers fast, precise quarter-turn flow control in demanding process lines.
AYVAZ KV-4 Butterfly Valve DN50 is engineered for precise flow control in industrial process automation. In addition, its DN50 lug type connection simplifies mounting and maintenance. Therefore, it suits process skids, manifolds and automated line sections where reliable quarter-turn operation is essential.
The GG-25 cast iron body delivers strength, and the AISI 316 stainless steel disc resists aggressive media. Moreover, the AISI 420 stainless steel stem adds mechanical durability under frequent cycling. The double-acting pneumatic actuator works both ways through independent air ports. Consequently, the valve holds a PN16 rating, 16 bar working pressure and a maximum operating temperature of 130°C, sealed with H-EPDM gaskets.
