These 12-Volt DC electric solenoid valves with barbed inlet and outlet ports are great for projects. A model: These types of valves are often used for automatic faucets, foot operated faucets, drinking fountains etc.
NOTE A model: Please note that diaphragm-type solenoid valves are NOT suitable for gravity-fed systems (i.e. draining liquids out of containers or tanks without using a pump) because of the 3 psi minimum pressure requirement. Check our other auctions for direct acting valves which are suitable for gravity-fed systems. B model: This routine for no pressure valve, apply to 0-0.2 MPA water pressure, used in ordinary water machine!
Water flow characteristic: 0.02 Mpa greater than 0.4 L/min; 0.10 Mpa greater than 1.5 L/min; 0.30 Mpa greater than 3.5 L/min; 0.80 Mpa greater than 6 L/mi. This valve is normally closed type solenoid valve, the electricity on (water), power off(no water), in the direction of flow is towards the arrow direction (reverse connect does not work)
As its name suggests,pressure is the water pressure,No pressure that is no water pressure.Pressure applied to 0.02 - 0.8Mpa water pressure,no pressure applied to 0 - 0.2Mpa water pressure.Solenoid valve that not using within the range of normal pressure can not work normally.
