The U.S. Solid electric solenoid valve features a durable brass body, suitable for outdoor but not underwater use. It's favored by customers for DIY projects, moderate temperature and chemical applications, as well as for controlling flow in irrigation, reverse osmosis, and motorcycle systems.
Most U.S. Solid Valves are UNIDIRECTIONAL
Make a note of the arrow on your valve. Most U.S. Solid valves are unidirectional. This means they are intended to flow in one direction only, in the direction of the arrow. If connected in opposite directions, the valve will not actuate properly (will not close for Normally Closed valves). Additionally, be sure the medium passing through is filtered. If not, particles will cling to the gasket over time, which can cause it to not seal properly.

THREADING
U.S. Solid Valves follow National Standards for pipe thread. We suggest the use of Teflon tape to ensure the seal of the NPT threading. The tapered male and female thread form angled surfaces that with increased torque squeeze the Teflon tape resulting in a tight seal.

About Filter Installation
To avoid valve issues like leakage or jamming, make sure to install a filter if the water contains particles. If the valve can't fully open or close, it may be clogged with impurities. In this case, open the valve and clean the internal components.
