“FLOW-ON” 3-way Control valve is a lightweight valve used in low flow process as a mixing valve. It is designed as a 3-way body with two inlets for two separate flow streams in common outlet for creating third fluid. This mixing diverting control valve is made to control a variety of fluids such as water, steam, and gases. The main feature of our valve is the top guided construction which ensures smooth traveling of stable plug over entire stroke for minimizing wear and tear loss.

Our control valve is made to work in different heating or cooling application for controlling hot, cold and other fluids. These valves can work in modulating or two position control system. Our mixing valves have two inlets with one outlet, and diverting valves have one inlet with two outlets. Some people refer 3-way valves as a mixing valve but these valves can also be known as constant flow valves or bypass valves. These mixing diverting control valves are used in mixing service for direct flow of one inlet to a common outlet or in diverting service for direct flow of common inlet to any one of two outlets. These diverting and mixing valves are not interchangeable with each other.
