What is the recommended operating pressure range for the Rotary head ST-458 with ceramic insert and 20Â° spray angle?

The recommended operating pressure range for the Rotary head ST-458 with ceramic insert and 20Â° spray angle is 200â400 bar.

How should the Rotary head ST-458 with ceramic insert be identified by color for calibration purposes?

The Rotary head ST-458 with ceramic insert should be identified by its calibration color marking: each ST-458 unit is marked with a distinct color corresponding to its calibrated spray characteristics (spray angle 20Â°). Use the color code shown on the nozzle body for calibration identification when setting up at the operating pressure range 200â400 bar; the colored marking ensures correct selection and repeatable performance (materials: brass/plastic with stainless steel adapter; max operating temperature +100Â°C).

Can the Rotary head ST-458 with ceramic insert be used continuously at temperatures up to +100Â°C?

Yes. The Rotary head ST-458 with ceramic insert is specified with an operating temperature "up to +100Â°C," so it can be used continuously at temperatures up to +100Â°C. Ensure the rest of your system components (hoses, seals, adapters) are also rated for continuous operation at that temperature and that working pressure remains within the specified 200â400 bar range.
