Pneumatic Single-Seated Control Valve, DN40, PN16, CF3M
Key Specifications / Features
Hits: 3
Introducing Pneumatic Small-Port Cage-Guided Single-Seated Control Valves, designed for high differential pressure service over 2940 kPa (30 kgf/cm²) and heavy-duty conditions like flashing or cavitation. The robust guides and protective cage prevent valve body erosion. The compact valve body with an S-shaped flow passage ensures low pressure loss, high flow capacity, and rangeability. Valve plugs come in a wide range of Cv values, and the flow shutoff performance features a simple yet powerful diaphragm actuator with multiple springs. Ideal for reliable control of small flows in high/low-temperature, high differential pressure lines. Sizes: 3/4 to 3 inches, Materials: ASTM A351 CF3M, Pressure Rating: ANSI Class 125, 150, 300, 600 LB.
