Pneumatic Cage-Guided Control Valve, 3/4-3 IN, ASTM A216 WCB
Key Specifications / Features
hits: 0
Our Pneumatic Small-Port Single-Seated Control Valves, made from ASTM A216 WCB, operate within a temperature range of -196 to +450°C. Designed for high differential pressure services where pressure exceeds 2940 kPa (30 kgf/cm²), these valves excel in heavy-duty applications prone to flashing or cavitation. Their 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 excellent rangeability.
Flow characteristics include equal percentage and linear options. Available in ANSI Class 125 LB, 150 LB, 300 LB, and 600 LB. End connections: Flanged (FF, RF, RJ, LG), Welded (SW, BW), and Threaded (Rc, NPT).
