Product Details

Description

This professional-grade liquid flow control switch is an essential safety component designed to monitor and regulate fluid movement within high-pressure industrial and commercial systems. Rated for up to 150 PSI, this high-limit control switch protects critical equipment like compressors and pumps by ensuring they only operate when sufficient liquid flow is detected. Featuring a durable NEMA-rated enclosure for enhanced protection against environmental factors, this switch is ideal for use in water-cooled chillers, HVAC systems, and other large-scale liquid-handling appliances. Its precision sensing technology provides a reliable fail-safe, preventing system overheating or mechanical failure due to low-flow conditions.
