NC Normally Closed]: This is a normally closed type electric solenoid valve, turn it on to open and turn it off to close. [High Pressure and High Temperature Withstand Ability]: High quality zinc alloy valve body can hold press up to 0.8 MPa and liquid temperature from -5 to 100°C, high pressure and high temperature withstand. [Intermittent Time Work]: This solenoid valve is suitable for short time intermittent time work. It is preferable that the continuous power-on time is less than 30 minutes. [Usage Environment]: This solenoid valve is designed to be installed indoors horizontally in a dry environment. If used outdoors, the coil part should be well protected from water. [Application]: Suitable for use with pipelines in non-corrosive applications of water, air, gas and low viscosity fluids.
