Dwyer L6EPB-B-S-3-O Liquid Level Float Switch Spdt

Product Description

The DWYER L6EPB-B-S-3-O is a liquid level float switch built for industrial and commercial fluid management applications. It features a 1-inch threaded connection, a maximum operating pressure of 1000 psi, and a maximum temperature rating of 220 degrees F. The switch uses SPDT (Single Pole, Double Throw) logic, giving installers flexibility for both normally open and normally closed circuit configurations. The stainless steel stem provides corrosion resistance in wet or chemically aggressive environments, while the brass body offers durable sealing at the process connection. Licensed plumbers, HVAC technicians, and industrial maintenance technicians typically install this switch in pressurized tank and fluid control systems.

This float switch is suited for residential and commercial liquid level control across a wide range of process environments. Typical applications include automatic tank dump operations, direct pump control for maintaining set liquid levels, and level alarms in sumps, scrubber systems, hydro-pneumatic tanks, boilers, and water and wastewater treatment processes. It also serves valve control duty where a discrete level signal is needed to open or close a downstream actuator. The 1-inch float diameter and low minimum operating temperature of 4 degrees F extend its usable range into cold-climate installations.

Key Features

• SPDT switch logic supports normally open and normally closed wiring configurations
• 1000 psi maximum pressure rating for use in high-pressure tank and process systems
• 220 degrees F maximum temperature rating
• Stainless steel stem resists corrosion in wet and chemically active media
• Brass body construction at the process connection
• 1-inch threaded connection for direct mounting to standard process fittings
• Minimum operating temperature of 4 degrees F supports cold-environment installations

Compatibility

Designed for use in automatic tank dump operations, direct pump control, level alarms in sumps, scrubber systems, hydro-pneumatic tanks, boilers, and water and wastewater treatment processes, as well as general level and valve control applications requiring a 1-inch threaded float switch.

Installation Notes

Installation should be performed by a licensed plumber or qualified industrial technician following applicable IPC and local process piping codes. De-energize all electrical circuits and depressurize and isolate the tank or vessel before mounting or servicing the switch. Verify thread type and sealant compatibility with the process fluid before making up the connection. Do not exceed the rated pressure or temperature limits during operation or pressure testing.
