Pneumatic Cage-Guided Flow Control Valves, 3/4 Inch, DN20-DN80
Key Specifications / Features
Pneumatic Small-Port Cage-Guided Control Valves are tailored for high differential pressure services where fluid pressure exceeds 2940 kPa (30 kgf/cm2), or in heavy-duty operations prone to flashing or cavitation. Their robust guides and cage protect against erosion, ensuring durability. With a compact design featuring an S-shaped flow passage, these valves offer minimal pressure loss, facilitating ample flow capacity and rangeability. Offering various Cv values for valve plugs, they boast reliable flow shutoff performance via a compact diaphragm actuator with multiple springs. These versatile valves are ideal for precise control of small flows in high or low-temperature, high differential pressure systems.
