2 Inch Black Square Nitrile Rubber Diaphragm 2W500 for Solenoid
Water Valve
A very thin-walled diaphragm can withstand high pressures while
remaining very flexible and responsive to minior pressure
variations
Fabrics made of polyester, nylon and silk ard commonly used for
most applications, fabric used for those applications exposed to
high temperature. For those applications that require extremely
high strength.
All types of elastomers, such as nitrile, EPDM, fluorocarbon,
neoprene, silicone, fluorosilicone, can be used in the
fabric-reinforced diaphragms.
Fabric-reinforced diaphragms offer advantanges of no leakage, no
lubrication, no breakaway force, no friction, high strength,
functionality over wide pressure ranges, low cost, simple design,
versatility.

Working principles of solenoid water valve
This valve is the pilot type solenoid valve of the second opening
valve. Its structure is mainly composed of the pilot valve and the
main valve. The main valve adopts the rubber sealing structure.
When in normal position, the guide valve is sealed with movable
iron core, the pressure in the valve chamber is balanced, and the
main valve is closed. When the coil is energized, electromagnetic
force is generated to absorb the moving iron core, and the
dielectric self-guiding valve mouth in the main valve cavity is
discharged, resulting in pressure difference. The diaphragm or
valve cup is quickly lifted, and the main valve mouth is opened,
and the valve shows a path. When the coil power off, the magnetic
field disappeared, the resetting of the active iron core, closed
valve mouth, valve and the main valve chamber pressure balance, the
valve was closed state.
Brass solenoid valve installation notes
1, brass solenoid valve installation should pay attention to the
arrow on the valve body should be consistent with the flow
direction of the medium. Do not install in a place where there is
direct dripping or splashing water. Brass solenoid valves shall be
installed vertically upward.
2, brass solenoid valve should ensure that the power supply voltage
is 15%-10% of the rated voltage fluctuation range of normal work.
3. After installation of brass solenoid valve, there shall be no
reverse pressure difference in the pipeline. And need to be
electrified several times, make it suitable for the temperature
before the formal use.
4, brass solenoid valve should be thoroughly cleaned before
installation. The medium should be free of impurities. Install
filter before valve.
5, when the brass solenoid valve failure or cleaning, in order to
ensure the system continues to operate, should be installed bypass
device.
