FESTO solenoid valve failure emergency treatment and applicability
When festo solenoid valve suddenly a problem, nor the replacement parts can be used for emergency treatment in the following way: a hand to toggle the solenoid valve connector until you hear the “despair”, presses connector, and then with plastic sheets with wrapped tight, then the input line and pull the plug, for a touch from test if the sound of “despair, despair,” the action, that has returned to normal, may continue to use. Note that the above process should be in the ignition switch status.
Confirm the idle solenoid valve damage, to restore the role of the idle speed. Remove the solenoid valve, and blocked with a suitable plug, so that does not leak. In this way, the solenoid valve will lose its function, as there is no idle solenoid valve of the carburetor.
FESTO solenoid valve for control accuracy
a,ction time: refers to the electrical signal is turned on or cut off the main valve action completion time, only multi-function solenoid valve of the Company’s patented product can open and close time were adjusted not only to meet the control precision, but also to prevent water hammer damage .
b,ordinary solenoid valve only opening and closing two locations, please choose the number of solenoid valves in the control of high precision and parameters for a smooth. leakage sample given on the amount of leakage values ??for common economic level, and if too high, please make a special order.
Application of power
a,power supply types, were selected to AC and DC solenoid valves. Generally speaking, access to convenient AC power.
b,voltage specifications used as preferred AC220V.DC24V.
c,the power supply voltage fluctuation usually exchange selection % -15%, DC to allow ± so, should the ultra poor, to be taken by the regulator measures or make a special order.
d,should be based on the rated current power capacity and power consumption. It should be noted that the VA value of the start of the exchange higher, lack of capacity should be preferred indirect electromagnetic valve.
Application of environmental
a,The maximum and minimum temperatures, the environment should be selected within the allowable range, if ultra-tolerance required for special orders.
b,relative humidity of the environment and water droplets and rain and so on, should be selected the water solenoid valve.
c,vibration, bumps and impact on the environment, often to be elected a special species such as marine solenoid valve.
d,use in a corrosive or explosive environments should give priority to the security requirements selection of resistance to hair loss.
e,the environmental space restricted, please use the multi-function solenoid valve, which eliminates the need for bypass and three manual valves and easy online service.
Suitable medium:
1,gas liquid or mixed state, respectively, use different varieties of solenoid valves.
2,medium temperature products of different specifications, otherwise the coil will burn, seals aging, seriously affect the life. The medium temperature should be chosen within the scope of the solenoid valve allows.
3,medium viscosity, usually 50cSt the following. Exceeds this value, the diameter less than 15mm high viscosity solenoid valve.
4,medium cleanliness should be in front of the electromagnetic valve fitted with recoil filter valve. Medium If the directional flow, and not allowed back.
Applicable to the pipeline:
a,valve openings and model, according to media flow requirements and pipe connections.
b,selected according to the flow and valve Kv value, nominal diameter, but also optional with the pipe diameter.
c,the minimum working pressure of the working pressure 0.04Mpa above is the choice of indirect Pilot; minimum working pressure close to or less than zero must use direct action or step-Direct.
CKD solenoid valve automation infrastructure components used to control the flow direction, belonging to the actuator; normally used for machine control and industrial valves above, control the direction of the medium, so as to achieve control of the valve switch. Working principle of the solenoid valve closed chamber with holes in different locations, each hole leads to a different pipeline, cavity intermediate valve, on both sides of the two electromagnets,piston driven piston rod, piston rod driven by a mechanical device to move. So that the electrical current through the control of the electromagnet off on the control of mechanical motion.
