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
