Pneumatic Diaphragm Globe Control Valve, Cage-Guided, CF8M
Key Specifications / Features
Hits: 4
Our Pneumatic Small-Port Single-Seated Control Valves are designed for heavy-duty service. The compact valve body, featuring an S-shaped flow passage, ensures low pressure loss, large flow capacity, rangeability, and high accuracy flow characteristics. Equipped with a multi-spring diaphragm actuator, the control valve is compact and delivers substantial output force.The valve plugs come in a wide range of Cv values. Flow shutoff performance uses a simple yet powerful diaphragm actuator with multiple springs. Materials: ASTM A351 CF8M. Temperature Range: -196 to +450°C. Flow characteristics: Equal percentage, Linear. ANSI Class 125 LB, 150 LB, 300 LB, 600 LB. These control valves are ideal for reliable control of small flows in high- or low-temperature, high differential pressure process lines.
