HAV Venturi Angle Valve
The HAV Venturi angle valve is a control valve with a top-guided structure. The valve body features a smooth flow path, resulting in low pressure drop loss and large flow capacity. The valve core has a large guiding area, ensuring excellent vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which is compact in structure and provides large output force. Angle valves are widely used to control fluids containing particles, slurries, viscous fluids, or flashing fluids.
