Washing Machine Water Inlet Valves - Cheap Source of Solonoid Control Valves?


All,
I'm looking for a cheap source for a electrically controlled solonoid control valve. I've found washing machine water inlet valves as cheap as $12.00. I want to build a cooling system that will swich the output of a pump to up to several different outputs. When I first saw the water inlet valves, I thought GREAT! all I have to do is hook my pump output to the inlet valve output. That way, I'd get two valves for one water inlet valve (one from the hot water input and another from the cold water input). After digging into it a little bit, I found out that the flow through these valves is only one way and that at least 30PSI is required in the proper direction.
My Question:
Is this true for all water inlet valves? Why? Is there a check valve in there? If so, can I disable it somehow?
Any help is appreciated.

Some solenoid valves are direct-operated; others are "pilot-operated". In the latter, the solenoid only controls a tiny orifice. This lets fluid (air,water,gas, etc.) flow to a large diaphragm or other element which actually controls the larger main valve.
Short answer: No, you can't "disable" anything inside.
You *might* get away with something like a lawn sprinkler valve. These are pilot-operated too but maybe more tolerant of your pump's output. They \\are high flow and reasonably priced.
