Product Overview

The HCB Series balanced cage single-seat control valve is designed for heavy-duty service. Its compact body has an S-shaped flow passage and a flow-directing vane that regulates turbulent flow around the cage, giving low pressure loss, large flow capacity, wide rangeability, and high-accuracy flow characteristics. The pressure-balanced valve plug allows control of high differential pressure with a small actuating force.

Key Features

• Pressure-balanced plug structure for high differential pressure control with a small actuating force
• Straight-through and angle types, with high-performance sealing rings on the plug or cage
• Excellent dynamic stability, low noise, and minimal cavitation corrosion
• Compact multi-spring diaphragm actuator or cylinder actuator, for a compact structure and high output force
• Design conforms to IEC 60534-2-1-2011; leakage meets ANSI FCI 70-2-2013
• Customizable for special requirements
