COI TECH SLK Type D Safety Valve

The Rhodes 400 sight flow indicator is designed for optimal performance, featuring either a high sensitivity spinner or a ball that operates from just 0.7 litres per minute (when using water). Constructed with nitrile seals, a nylon spinner, or a PTFE ball, this indicator offers exceptional chemical resistance. The stainless steel version further enhances durability by including borosilicate glass as a standard feature.

These compact sight flow indicators are widely utilised in plant protection applications, effectively displaying the flow of coolant or lubrication to pumps, compressors, and engines. One of the significant advantages of the Series 400 is its versatility; it can be installed in any orientation, with the exception of the ball type, which requires horizontal positioning.
