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.
|Model||2w400-40 water valve diaphragm|
|Hole number for mounting||4|
|Working medium||Water, Clean Air|
|Diaphragm working life||More than 1 million cycles|

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.
