Potable water valves provide bi-state flow control for food/beverage applications. With cost-effective Nylon 6 plastic bodies, these NSF certified valves (NS201 and NS211 series) offer piloted-diaphragm operators, with various orifice sizes and solenoid voltages. Zero-differential models do not require a minimum pressure to operate.

The valves themselves are solid units. However, the stainless fasteners that hold the valve together gall and seize with the stainless threaded inserts at an alarming rate. If you ever need to disassemble the valve, for the love of all that is holy use some kind of penetrating oil on the threads before turning the fasteners and put anti-seize on the threads before putting it back together. I purchased 9 valves for a project and every one of them had at least one fastener that galled while being removed. After removing the fasteners, they all required chasing the threads to clean them up. FYI, the fasteners were being removed to mount the valve body onto a bracket.
