Manufacture: Azbil Corporation
Model: HLC

A single-seat control valve suitable for high differential pressure service where the fluid’s normal differential pressure exceeds 2940 kPa, and heavy-duty service where flashing or cavitation may occur.

• Compact, high performance, and prevents erosion
• Large Cv value and rangeability
• The flow shutoff performance is compliant with IEC and JIS standards
• Compliant with IEC 61508 functional safety standards
