Custom Black Nitrile Rubber Diaphragm 2W320 for Electromagnetic
Water Valve Medium with Water/Oil
As the diaphragm is a flexible mechanism that needs to be opened
and closed frequently to control air circulation, it is required to
have good flexibility and as high tightness as possible. Therefore,
the material of the diaphragm is directly related to the service
life and efficiency of the diaphragm.
In other words, the quality of the diaphragm will directly affect
the working stability of the machine and directly affect the use
cost of the equipment. Generally, the diaphragm has the promise of
service life or operation times. The use of high-quality diaphragm
can directly reduce the use cost of the working equipment.

Description of water solenoid valve
Water solenoid valve has closed cavity, in a different location to
open a hole, each hole leads to different tubing, cavity valve is
among, both sides are two electromagnets, which face the magnet
coil electricity body will be attracted to which side, by
controlling the movement of the valve body blocked or leakage of
different discharge of oil hole, and the oil hole is always open,
hydraulic fluid will enter the different oil drain, and then
through the oil pressure to push the cylinder piston, piston drives
the piston rod, piston rod drive mechanism. This controls the
mechanical motion by controlling the current in the electromagnet.
2W series water solenoid valve is the use of media pressure
difference work of direct moving electromagnetic valve, it USES
diaphragm structure, with open and close quickly, stable
performance, easy to use, high reliability, long life and other
characteristics; The valve is highly resistant to contamination.
The electromagnetic valve fault and eliminate:
(a)when electromagnetic valve does not work after the power supply:
1, check the power supply wiring whether bad -) connectors and
wiring connection again;
2, check whether the power supply voltage in the plus or minus
working range --) to switch to normal position;
3, whether the ring sealing off -) to welding;
4, coil short circuit, replace the coil;
5, differential pressure is not appropriate to work -) -) or
replacement of proportion adjustment pressure difference
electromagnetic valve;
6, fluid temperature is too high -) change of proportion of
electromagnetic valve;
7, have impurities to make electromagnetic valve of the main valve
core and the moving core card die -) cleaning, such as seal damage
the seal and install the filter should be changed;
8, the liquid viscosity is too large, high frequency and life
expectancy has to -) replacement products.
