The sprinkler valves will probably hold up just fine, as there is a small SS screw holding the diaphram.

The problem is they are a pilot operated valve, meaning they use the line pressure to actuate the valve. Our systems are low pressure, and they generally need about 10psi differential pressure across the valve to open them.

The 10psi figure is from looking at several different brands of valves. Not sure if you could cut the spring, or modify the valve to operate on less pressure. They work great for their intended application, line pressure at your house. People do use them for running their RO/DI systems, since that application is line pressure.

You could get one on sale for $10 and play with it. let us know.
