Many times when a cream whipper stops functioning properly it gets thrown out and replaced with a new model. Save your coffee shop, bar or restaurant the cost of a new cream whipper by replacing the mixing head valve. The Stainless Steel Mixing Head Valve (03106-S) from Espresso Supply ensures that pressure is maintained in the cream whipper. Without proper pressure the whipped cream will not dispense or trickle out in liquid form. This mixing head valve fits models 03122, 03124 and 03125.
