Topaz trough valves are float operated valves for use in automatic filling of water troughs, tanks, cisterns etc. The valve is configured for above or below water mounting. The float operates a small pilot valve which in turn operates the main diaphragm valve. Topaz trough valves are a good choice where their high flow, compact, robust, non corrosive construction and high level of adaptability are needed.

Installed thousands of these in a critical environment HVAC. Reduces waterhammer. High supply unseat pressure. Easy to install, repair. Relatively inexpensive.

I am happy to pay more for a superior product, but this was poorly designed and simply didn't work. Even when extending the float well into a tank, it would not shut off the water. We tried every conceivable configuration, and the hydrostatic pressure from a full tank would not sufficiently elevate the float to completely shut the flow of water. DO NOT BUY (or if you do, be prepared for LOTS OF PROBLEMS).

Great piece of equipment. Very strong and durable. Fair price for something that is an important part of your setup. I would buy from this company again and again. Great work folks! Thank you for helping to solve my ball and valve issue with a quality product.

If you need a full flow autofill it is hard to beat these units. They are expensive but the quality is very good.

If you want to use it with just gravity fed water you need to choose a different product. You need water pressure behind it to open the diaphragm properly.
