Product Description

4V420-15 Pneumatic Electromagnetic Solenoid Valve

4V420-15 Double-position five-way pneumatic solenoid valve is generally used to control the double-acting cylinder. The working principle of a double acting cylinder is very simple. I have a piston in the cylinder. The two ends of the cylinder itself are connected by gas pipelines, which can make different movements under different ventilation conditions. The cylinder needs a solenoid valve to control the switch of the gas circuit and make the cylinder work. The on/off control of the solenoid valve is controlled by the TPC timing program controller, and various required actions such as timing control, position control, manual control, and automatic control can be realized by simple function setting.

CNC machine with 4V320-10 pneumatic control valve failure and maintenance:
CNC machine pneumatic system used in many types of control components, mainly a variety of valves, such as pressure control valve, flow control valve, direction control valve,4V pneumatic solenoid valve. These components play the roles of signal conversion, amplification, logic program control, pressure control, flow control and compressed air flow control in pneumatic control system. Numerical control machine tool pneumatic fault diagnosis and effective elimination is the guarantee of numerical control machine tool pneumatic fault. The premise that the system can work normally.

In the pressure control, the common faults of the reducing valve are secondary pressure rise, pressure drop (insufficient flow), air leakage, tire leakage, abnormal vibration and so on. The reasons for these failures are: pressure regulating spring damage, seat torsion or seat rubber peeling, dust into the valve body, the piston guide part of the friction resistance is large, and the valve body contact surface scratches, and so on: the elimination method is relatively simple, first to find fault location, find out the cause of the fault, and then solve the fault. Such as replacement of damaged springs, seats, valve bodies, seals, etc.; Meanwhile, clean and check the filter, then mix the -il impurities; Note the specifications of the f-select valve to fit the actual requirements.

Common safety valve (overflow) failures are: although the pressure increased but no overflow, but the pressure did not exceed the set value, but overflow, vibration, valve body and cover leakage. The main reason of these faults is that the impurities or foreign bodies in the valve block the valve hole or block the moving parts of the valve. CNC machine pressure regulating spring damage, seat damage; Diaphragm rupture, seal damage; Upward pressure. Slow speed, valve discharge flow is too large, resulting in vibration. CNC machine solutions are also relatively simple, replacement of damaged parts, seals and springs; Pay attention to the inside of the cleaning valve and fine tune the overflow flow to match the pressure rising speed. A flow regulating valve, that is, throttle valve is relatively simple, such as failure can refer to the previous description to solve.

The fault of reversing valve is the most common and typical fault of reversing valve. Common failures are irreversible, leakage, or vibration. The causes of these faults are: poor lubrication, large sliding friction, large initial friction; The seal has larger compression or expansion deformation; Dust or oil stains on the slide block or valve seat; Spring stuck or damaged; The amount is too small or is damaged; Stem or seat damage; The house has contracted L; Low pressure (pilot), low voltage (4V pneumatic solenoid valve), etc. CNC machine solutions are also very simple, that is, for the fault phenomenon, targeted cleaning, replacement of damaged parts and seals, improve lubrication conditions, improve the power supply voltage, increase the pilot operating pressure.
