Installation notes
Correctly Couple the Actuator to the Limit Switch Shaft
During installation, ensure that the limit switch shaft is correctly coupled to the quarter-turn actuator and securely fastened so that actuator movement is accurately transmitted to the device shaft, preventing abnormal end-position feedback.
Set the Cams According to the Actual End Positions
During commissioning, set and secure the cams according to the actual endpoints of the valve's rotational travel, and verify the end-position information output by the switching elements to prevent incorrect or lost limit signals caused by cam movement.
FAQ
How does the Neles Easyflow K Series detect the end positions of a valve or actuator?
The K Series transmits the actuator's rotary motion through the device shaft to preset cams. The cams then actuate inductive or mechanical switching elements to provide end-position information for the required rotational travel. The switching elements can be connected to an external monitoring system and are suitable for quarter-turn actuators and valve assemblies.
What interface and adjustment features does the Neles Easyflow K Series offer when mounted on a quarter-turn actuator?
The K Series is equipped with a VDE/VDI 3845 mounting interface and a NAMUR shaft and can be mounted on top of nearly all quarter-turn actuators. Color-coded cams facilitate end-position adjustment, while the large, highly visible visual indicator makes it easy to observe the position status in the field.
What switching types are available for the Neles Easyflow K Series, and what wiring function does the mechanical configuration provide?
The K Series offers inductive and mechanical switching options. Configurations equipped with mechanical switches include solenoid valve terminals inside the limit switch enclosure for solenoid valve wiring.
What is the difference between the cable entries of the Neles Easyflow KS and KC Series?
The KS Series is equipped with two cable entries, while the KC Series is equipped with three. The KS Series uses a standard enclosure with M20×1.5 cable entry options. The two series can be differentiated according to the required number of cable entries during selection.
Which specifications should be checked when selecting the Neles Easyflow KS Series for flushing or corrosive process environments?
The KS Series features a die-cast aluminum (LM6) enclosure with an epoxy powder coating, an IP67 enclosure rating, and a temperature range of -40 °C to +100 °C. Hazardous-area certifications include ATEX and CCOE. Applications for the K Series include corrosive and flushing process environments in industries such as food and beverage, chemical processing, pharmaceuticals, and biotechnology. During engineering selection, verify the site temperature, ingress protection requirements, and hazardous-area certification requirements.
