Model 331 valves are balanced, cage guided 3-Way mixing valves that can be used for either flow-mixing (converging) or flow-splitting (diverging) service applications.
Model 332 valves are unbalanced, cage guided 3-Way mixing valves that can be used for flow-mixing (converging) service applications. 332 valves can also be used for flow-splitting (diverging) service applications if used for on/off flow control only.
