U.S. Solid normally closed (N/C) electric solenoid valve is constructed with a Stainless Steel body, 1/2" female threaded (G) connections, and strong VITON gasket.
FLOW DIRECTION: Make note of the arrow on your valve. Most U.S. Solid solenoid valves are unidirectional. This means they are intended for flow in one direction only, in the direction of the arrow. See Figure 1 for location of arrow. If connected in opposite direction, 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 British Standard Pipe Thread(BSPT). We recommend use of Teflon tape to ensure seal of the threading, as shown in Figure 2. It is suitable to liquids, gases and even for high vacuum.
POLARITY: For valves with 2 wires, the valve will actuate regardless of which terminal each wire is connected to (+ or -).
PRESSURE: All solenoid valves need some pressure to actuate. This is especially true of pilot, or indirectly operated valves.
Suitable for outdoor use; not for use underwater. Suitable for use with hot or cold water, natural gas, air, very low viscosity fluids (< 20 cst) and gasoline or other petroleum based liquids. Customers chose this general purpose valve for supplemental gas tanks, sprinkler systems, and more. This solenoid valve is not to be used continuously for more than 8 hours. It can result in the valve overheating.
