Pneumatic Actuated Flanged Floating Ball Valve

The Pneumatic Actuated Flanged Floating Ball Valve is a versatile and reliable solution for automated flow control in industrial systems. Featuring a full port design and a floating ball, it ensures minimal pressure drop and tight shutoff performance. Constructed with a durable stainless steel body or carbon steel as the body material, this valve is built to withstand harsh conditions and meet fire safe standards. Equipped with a pneumatic actuator, it offers both spring return and double acting operation modes for flexible automation. Integrated limit switches provide precise valve position feedback, making this actuated ball valve ideal for critical applications requiring safety and efficiency.
