SAx
SAx (Sepanta Electronic Tabarestan) is an industrial flame detection and monitoring brand specializing in advanced flame scanners, detectors and combustion safety systems for critical industrial applications. The company’s products integrate optical sensing (UV/IR) with digital signal processing to identify flame presence, intensity and stability inside combustion chambers. SAx flame scanners and detectors are used in power generation, refineries, cement plants, waste-to-energy facilities, steam generation systems and petrochemical processes. Engineered for robust operation across wide temperature ranges and harsh environments, SAx systems support fuel safety, combustion control and equipment protection in industrial burners and turbines.
Frequently Asked Questions
What types of valves are compatible with SAx electrical actuators?
SAx actuators are highly versatile and can be mounted on a wide variety of globe, shoe, and butterfly valves. They utilize standard mechanical interfaces and stroke adaptations to ensure seamless integration into diverse HVAC and industrial process control systems.
Do SAx actuators support proportional control signals?
Yes, SAx modulating actuators are designed to accept standard continuous control signals, such as 0-10V or 4-20mA. This allows for precise, stepless positioning of the valve, ensuring accurate regulation of flow rates and temperatures.
How do SAx actuators handle power failures during critical operations?
Certain SAx actuator models are equipped with mechanical spring-return mechanisms or electronic fail-safe functions. In the event of a power loss, these safety features automatically drive the valve to a predefined safe position to protect the system.
Can the running time of a SAx actuator be adjusted in the field?
Many SAx actuators feature configurable running times that can be adjusted via internal DIP switches or digital configuration tools. This flexibility allows commissioning engineers to optimize the response time according to the specific dynamics of the control loop.
Are SAx actuators suitable for outdoor installations?
Depending on the specific model, SAx actuators offer high IP protection classes (such as IP66) and built-in condensation heaters. These environmental protections make them highly reliable for exposed outdoor installations and harsh industrial conditions.
