Two material valves alternate the material flow from two material sources. Time settings are used to proportion each material. Materials can be drawn from containers or directly from a granulator. When you load from a granulator, it must be emptied at the end of each load. You can set the number of valve cycles to mix the two materials effectively.
The body of the two material valve is laser cut from structural steel. It is up to four times thicker than the competitive valves. Made from 304 stainless steel, they are designed to be resistant to abrasion.
Both the inlets and cylinders can be replaced and maintained off the valve body. In the event of abrasive wear to the inlet it can be replaced, that means you will not have to buy a new valve. The internal valve seal is replaceable, doubling the life of the valve seal.
Standard two material valves operate with a single solenoid causing both valves to move at the same time with the material still flowing. As much as thirty percent of the cycles a valve will close on material disabling the vacuum. When that happens, the entire next load fails. Missing load changes the proportion and can cause grinders to clog. Using two solenoids allows both valves to remain open for a delay between change. With both valves open, the air is reduced, stopping all material flow. Then the valve can close with a clean seal.
