The reason why there are many potential ASCO solenoid valve failure, so they are considered to be complex and prone to failure of the device. In fact, they are very simple, very reliable. Many problems are caused due to outside of the valve, and other problems are due to improper application or the installation is not correct. ASCO solenoid Industrial Valves shall check the voltage and the pressure from the input to begin troubleshooting. Problem may be due to not work control relay or due to fluctuations in pressure regulator. If the voltage and the pressure inspection, observation of valve. Direct acting solenoid Industrial Valves can't work for the following reasons: low voltage or voltage; The electromagnetic coil burn out; Pressure is higher than the rated pressure of valve; There are external impurities in valve; Core tube valve core stuck or damaged. To maintain normal work, when the coil current, electromagnetic valve core movement in the core tube and contact plunger nut. Should be able to hear when the electricity sharp metal click sound, provided to the coil voltage must be at least 85% of the nameplate rated voltage. If the solenoid coil voltage is correct, but I did not click sound could mean pipe pressure is higher than the rated pressure, to inspect. When troubleshooting of four-way valve control cylinder, must follow the valve with the manual. Some of the four-way Industrial Valves oil mist lubrication device is needed to work properly. Pilot control four-way valve usually require the full size of the pipelines, used as a pressure inlet pipe and outlet pipe. In some of the valve shall be in cylinder according to the joint, speed control device. Because of failure of cylinder is usually caused by itself, therefore should check whether the following situations exists. If qualified tube voltage, external impurities that may block valve core movement in the core tube. If the top of the valve core is hitting more than millions of times, the valve plate expansion or being cut, or damage to the valve core itself can limit the movement of the valve core. Pilot operated valve operation although hear a click sound when electricity, also may not be able to work. Produce no flow conditions may be caused by the following reasons: lack of pressure drop through the valve; Diaphragm rupture or damage of piston ring; The guide hole blockage or restricted. When current pilot operated and direct acting valves operation can work may be caused by any of the following reasons: control circuit malfunction; in the scale and other foreign matter; core stuck or core pipe damage; Spring break. Pilot operated valve operation when power failure may also be due to the following reasons: pressure relief hole plugging; seat or valve disc damage; Diaphragm or piston damage; Insufficient pressure drop through the valve. Electromagnetic valve noise is too large, Hum or shock) May be caused by the following reasons; The voltage is too low; Relay failure or electronic control signal is not correct; Electromagnetic valve parts loose; On the valve core or plunger surface of the nut with external impurities; Spring damage; The system pressure is too high. The piston rod and the connection between load on. Lack of lubrication; Piston cup wear or leak, allowing the fluid discharge valve; Control system including external impurities; System overload, the pipe pressure is too low, the size of the hose or joint is too small if the problem is not in the cylinder, the check valve.
