Dwyer Instruments V6EPB-B-S-2-B Flow Switch

The Dwyer Instruments V6EPB-B-S-2-B Flow Switch is a high-performance explosion-proof flow switch engineered for the rigorous demands of industrial HVACR and process piping applications. Built with a robust brass upper and lower body, this compact flow switch from the Flotect V6 Series is a direct replacement for FS6-W-3/4, ensuring seamless integration into existing 3/4" systems. It features a factory-installed brass tee and a reliable SPDT snap action switch, designed to protect critical equipment like pumps, motors, and liquid-cooled engines from low-flow or no-flow conditions. Utilizing a unique magnetically actuated design, the V6EPB-B-S-2-B eliminates the need for bellows, springs, or seals, significantly reducing potential failure points. Its weatherproof and explosion-proof housing is UL and CSA listed for Class I, Groups A, B, C, and D, making it ideal for hazardous environments. The electrical assembly is field-replaceable without process shutdown, maximizing uptime for contractors and facility managers.

Key Benefits

• Industrial Durability: Machined from solid bar stock with a leak-proof design rated for pressures up to 1000 psig in brass configurations.
• Simplified Maintenance: The electrical module can be swapped without removing the unit from the pipeline, preventing costly system downtime.
• Explosion-Proof Reliability: Fully compliant with UL, CSA, and NEMA 4 standards for safe operation in volatile environments.
• Application Versatility: Suitable for monitoring flow in air, water, and other compatible gases or liquids across HVAC and oil applications.
• Precise Switching: Employs a free-swinging vane and magnetic linkage for consistent performance without mechanical fatigue.

Common Questions

Is the V6EPB-B-S-2-B compatible with fuel oil or diesel?
Yes, the Dwyer V6 series materials, specifically the brass and stainless steel components with ceramic magnets, are compatible with diesel and fuel oils.

Can I install this flow switch in a vertical pipe run?
While the switch can function in any orientation, factory flow rate calibrations are typically based on horizontal runs. For vertical installation, contact our technical team for set-point adjustments.

Does this unit require a specific seal for the conduit?
Yes, to maintain the explosion-proof rating, you must follow local electrical codes and use appropriate conduit seals within the hazardous area installation.
