Dwyer V6EPS-S-S-4-S Flotect Flow Switch, SPDT, 1-1/4” SS/SS

Overview

The Dwyer V6EPS-S-S-4-S Flotect Flow Switch is part of the proven V6 Flotect® Series miniature flow switches designed for industrial fluid monitoring and control. This compact device is engineered to reliably detect the presence or absence of fluid flow in pipelines with a 1-1/4” tee connection and provides a dependable SPDT (Single Pole Double Throw) electrical output to interface with control systems or alarms. 

Unlike mechanical linkage switches, the V6 series uses a magnetically actuated mechanism, which simplifies installation and enhances dependability by eliminating moving parts that wear out quickly. The switch is built with a rugged body and weatherproof construction that is also explosion-proof, making it suitable for use in hazardous locations and industrial environments where safety and uptime are critical. 

Constructed with a stainless steel upper and lower body and an SS tee, this switch delivers superior corrosion resistance and durability for oil, water, gas and compatible liquids. Its compact footprint allows easy insertion into a pipeline using a tee fitting, and the electrical assembly can be replaced without disassembling the switch body from the installation — reducing maintenance time and operational disruption. 

The V6EPS-S-S-4-S includes explosion-proof ratings and certifications that meet stringent safety standards, including IEC 60079-0 and IEC 60079-1 guidance, ensuring reliable performance in hazardous and industrial settings. 

This flow switch is commonly used for pump protection, motor safety, auxiliary pump sequencing, coolant flow interruption detection, air flow monitoring in heating coils, and alarm signaling for emergency systems — wherever automatic detection of flow or no-flow conditions is required.
