Tru-Flo™ is a Slow-Close valve control designed specifically for fire apparatus valves. This patented Hand-Wheel and Dial Indicator utilizes magnets to maintain the dial face in a stationary and readable orientation as the Hand-Wheel is rotated to fully open or closed valve positions
The Hand-Wheel can be mounted in any orientation, including horizontally for side mount control panels or vertically for top mount control panels
The indicating gauge is sealed and constructed of a polycarbonate, non-yellowing lens and case. The entire unit is corrosion resistant with brass and stainless steel components. The Hand-Wheel assembly incorporates four seperate low friction bearings for smooth operation
