DN65 150LB Pneumatic Globe Control Valve

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.

HCB Series Balanced Cage Single-Seat Control Valve

The HCB series balanced cage single-seat control valve includes both straight-through and angle types. These valves use high-performance sealing rings on the valve plug or cage. The valve body is compactly structured and equipped with a flow-directing vane designed to enhance the fluid balance around the cage, resulting in minimal pressure drop, high flow capacity, wide adjustability, and precise flow characteristics. This design conforms to the IEC 60534-2-1-2011 standard. The control valve offers excellent dynamic stability, low noise, and minimal cavitation corrosion. It meets the ANSI FCI 70-2-2013 standard for leakage. The valve is compatible with either a multi-spring diaphragm or a cylinder actuator, which provides a compact structure and high output force. The HCB sleeve control valve is suitable for managing various high-temperature and low-temperature high-pressure fluids and can be customized for special requirements.
