Application scenarios
High-Cycle, Frequently Switching On-Off Valves
Used for controlling frequently actuated on-off valves. The product is designed for frequently switching and high-cycle valves, offering high pneumatic exhaust capacity and built-in diagnostics to support valve availability and operational reliability.
Diagnostics and Predictive Maintenance for Process-Critical On-Off Valves
Used for status diagnostics and predictive maintenance of process-critical on-off valves. The product features built-in diagnostics designed to help ensure on-off valve availability in demanding processes, improve operational reliability, and reduce maintenance costs.
Selection points
Integrated pneumatic control with high exhaust capacity
Maximum exhaust capacity of 700 Nm3/h (Cv 6.4), suitable for on-off valve actuators requiring high pneumatic flow and helping reduce the need for additional pneumatic components and tubing arrangements.
Loop power supply, HART communication and 24 VDC signal compatibility
Uses a 4-20 mA loop power supply and supports HART communication. A U/I converter can be used to provide binary 24 VDC power or adapt control signals.
Built-in diagnostics for high-cycle on-off valves
Built-in diagnostic functions are suitable for frequently actuated and high-cycle on-off valves, supporting operating condition monitoring and predictive maintenance.
Wide operating temperature range
The operating temperature range is -40 °C to +85 °C, allowing selection based on site temperature conditions.
Hazardous-area certifications and enclosure material options
Ex d and Ex ia hazardous-area certifications are available. The body can be specified in anodized aluminum or stainless steel to meet site explosion protection and material requirements.
Installation notes
Power supply and control signal matching
Confirm that the site uses a 4–20 mA loop power supply and connect HART communication according to the configuration. When binary 24 VDC power is used, connection must be made through a U/I converter.
Exhaust path and pneumatic capacity
The maximum exhaust capacity of SG9000 is 700 Nm3/h (Cv 6.4). During installation, ensure that the exhaust port and exhaust path are unobstructed and that the pneumatic capacity meets the actuator's operating requirements.
Hazardous-area certification configuration
Before installing in a hazardous area, verify that the Ex d or Ex ia certification corresponding to the specific SG9000 configuration is applicable to the site hazardous area, and configure installation fittings according to the applicable type of explosion protection.
Ambient temperature range
The ambient temperature at the installation location must remain within the range of -40 °C to +85 °C. Exceeding this range may affect the controller's reliable operation.
