Model HCB Pressure Balanced Cage Type Control Valves are designed for heavy duty services. The compact valve body, having a S-shape flow passage that features low pressure loss and a stabilizer that regulates turbulent flow around the cage, allows a large flow capacity, rangeability and high accuracy flow characteristics.
The valve plug is structured in a pressure-balanced type that permits flow control of a high differential pressure with a small actuating force. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs. The model HCB valves are widely applicable for reliable control of high or low temperature, high pressure or high differential pressure process lines where dynamic stability, low noise, and cavitation/flashing resistance are required.
