3/8'' NBR Seals Unid Type Solenoid Water Valves Normally Closed
AC110V DC12V 2W040-10 UD-10
The shown is UNI-D type UD-10 solenoid valve, valve body is made of
brass; armature assembly is made of stainless steel 304; solenoid
coil is made of enameled copper wire; and the raw materials used
are of high quality. The valve operation design is direct acting at
zero pressure difference. The valve function is 2/2 way normally
closed, so it is widely used in Pipeling water control, Water
heater water supply, Air, Carwash, Coffee machines, Compressors,
Fuel gases, Industrial automation, Industrial washing machines,
Packaging, Steam, Thermoregulation, Vending, Water, Water
treatment.

Pipeline fluid controlling of Normally Closed Brass Solenoid Valve:
NORMALLY CLOSED valves OPEN when the coil is energized.
NORMALLY OPEN valves CLOSE when the coil is energized.
Seal Options: NBR: -5°C to 80°C, EPDM: -20°C to 120°C, VITON: -10°C to 150°C,
PTFE: -10°C to 180°C.
ALL Standard valves are supplied with CONTINUOUS DUTY COILS of the
proper class of insulation for the service indicated on the valve.
The coil temperature may become hot after being energized for
extended periods, but it is normal. Smoke or burning odor indicates
excessive coil temperature and should disconnect the power to the
coil immediately.
VOLTAGES: Standard: 12-24V DC and 24-110-220-230V/50-60 Hz AC. Voltage
tolerances: +10% –5% for DC, +10%-15% for AC;
SERVICE LIFE: The service life of the solenoid valve depends on the operating
conditions such as pressure, temperature, type of medium and the
voltage. Normally the Brando solenoid valves are reliable for more
than 1 million cycles.
