Pneumatic Solenoid Valve used with Pneumatic Cylinder,the Valve
control the cylinder motion pattern application for Automatic pipe
bender, cutter, mixer etc.Double control solenoid valves have
memory function. Internal hole adopts special processing technology
which has littleattrition friction ,low start pressure and long
service life.No need to add oil for lubrication.It is available to
from integrated valve group with the base to save
installation space. Affiliated manual devices are equipped to
facilitate installation and debugging.Several standard voltage
grades are optional.

Working principle:
There is a close cavity in the solenoid valve, and there are
through holes in different positions. Each hole leads to different
tubing. There are valves in the middle of the
cavity and two electromagnets on both sides. Hydraulic oil enters
different drain pipes and then pushes the piston of the cylinder
through the pressure of the oil. The piston
then drives the piston rod, which drives the mechanical device. In
this way, the mechanical movement is controlled by controlling the
current of the electromagnet.
Failure and repair:
First, the solenoid valve does not work after energizing.
Check whether power wiring is bad, re wiring and connector
connection.
Check whether the supply voltage is within the range of + - to
normal location.
Whether the coil is removed or re welded
Coil short circuit to replace coil
Is the working pressure difference inappropriate? Adjust the
differential pressure to replace the equivalent solenoid valve.
The fluid temperature is too high to replace the proportionate
solenoid valve.
Impurities jam the main valve core and the moving iron core of the
solenoid valve for cleaning, if the seal is damaged, replace the
seal and install the filter
The viscosity of the liquid is too high, the frequency is too high,
and the life has arrived.
Two, solenoid valve can not be closed.
Seal of main spool or iron core has been damaged. Replace seal.
If the fluid temperature and viscosity are too high, replace the
counterpart solenoid valves.
The impurity enters the electromagnetic valve to produce the valve
core or the moving iron core.
The life of springs has arrived or deformed to replace.
Throttle hole balance hole clogging and timely cleaning
Working frequency is too high or life expectancy has changed.
Three, other circumstances
Internal leakage to check whether the seal is damaged, and whether
the spring is assembled badly.
Leakage: connect loosening or seal is broken. Tighten screws or
replace seals.
There is noise when power is switched on, and the fastener on the
head is loose and tightened. Voltage fluctuation is not within the
allowable range, adjust the voltage.
Clean or replace the impurities or uneven surfaces of the core.
