NEW HKC APL-510N Limit Switch Box. VALVE POSITION MONITOR 15079

NEW HKC APL-510N Limit Switch Box.  VALVE POSITION MONITOR 15079 

The HKC APL-510N is a robust and reliable limit switch box designed for precise monitoring and feedback of valve position in industrial automation and process control systems. As a critical component in pipelines handling water, oil, gas, and other media, it provides remote indication of whether a valve is fully open, fully closed, or in an intermediate position.

This particular unit, identified by the code 15079, is a brand new, unused SEO (Supplier Excess Or Similar) product, ensuring high quality and performance at a competitive value.

Key Features & Benefits

• Real-Time Valve Position Indication: Equipped with a built-in cam mechanism that actuates micro-switches to provide discrete electrical signals (e.g., Open, Closed, Intermediate) to a control room or PLC.

• Rugged and Weatherproof Enclosure: Typically features a robust housing (e.g., aluminum, epoxy-coated) with a high IP (Ingress Protection) rating such as IP67, making it suitable for harsh outdoor and industrial environments, resistant to dust, moisture, and corrosion.

• Easy Installation and Configuration: The unit is designed for straightforward mounting onto the valve’s actuator yoke. The internal cams are adjustable, allowing for precise setting of the switch activation points to match the valve’s travel.

• Multi-Switch Configuration: The APL-510N can house multiple micro-switches (typically 2 to 4), allowing it to trigger different circuits for position feedback, alarm signals (e.g., for emergency shutdown), or to initiate subsequent process steps.

• Visual Position Indicator: Includes a clear, mechanical position indicator (flag) that provides local, at-a-glance visual confirmation of the valve’s status.

• Explosion-Proof Options: Certain models may be available with ATEX or IECEx certification for safe operation in hazardous areas where flammable gases or dust are present.

• SEO Value: Being an SEO product, this unit offers the same reliability and performance as a brand-new part directly from the manufacturer but is often available with faster delivery and at a lower cost.

Typical Applications

The HKC APL-510N is used across a wide range of industries for automated valve control, including:

• Water and Wastewater Treatment: Controlling gate valves, butterfly valves, and plug valves.

• Oil and Gas Industry: Monitoring ball valves and gate valves on pipelines and wellheads.

• Power Generation: Managing critical valve positions in boiler feedwater, cooling, and fuel systems.

• Chemical and Petrochemical Plants: Providing position feedback for valves handling various process fluids.

• HVAC and Fire Protection Systems: Monitoring isolation and control valves.
