HCB pneumatic cage sleeve control valve

Overview

HCB cage sleeve regulating valve is a top-guide type regulating valve. It is used with multi-spring diaphragm actuator assembly. It has high control precision, wide adjustable range, large circulation capacity, light weight and low height. The flow channel is S streamline type, which is especially suitable for high pressure difference and control of cavitation and flash fluid.
