Forklift Solenoid Valve

Forklift Solenoid Valves are magnetic devices. When a small amount of current flows through them, it causes a solid switch to shut down the electrical systems. It pushes a tiny plunger forth as an effect. Doing so makes the pinion gear engage with the teeth of the flywheel, causing the crankshaft to turn, and the IC engine will jump-start.

The starter houses the solenoid valve for a forklift, situated beneath the ignition key ring. This ring is often located on the side of the steering column. But specific forklift models may have this ring located on the dashboard as well.

To access the valve, one must first remove the panel that prevents the starter from being exposed. As soon as the starter disconnects, it will disconnect the valve as well. Depending on the type of forklift, you must follow various procedures to remove the valve.

Having low or dead batteries is a frequent issue that may cause the Solenoid to stop working. When the Forklift Solenoid is operating at low power, it will not ignite the starter. It is common to hear the loud clicking sound when the battery has to be recharged.

The valve body must be designed to be compatible with the fluid. It is also essential that the seals should work as well with the fluid. Some popular materials used for constructing valves are

  • Stainless steel

  • Plastic

  • Brass
  • Aluminum

Stainless steel is best for making valves. It comes in non-magnetic and magnetic options.

What is a Solenoid

A Solenoid is an electromagnet. Its function is to generate a regulated magnetic field through a coil wrapped into a packed helix. These coils are often used in electric motors. When an electric current is conducted through the coil, it may configure to produce a magnetic field in a specific volume of space.

Construction of Solenoid

A Solenoid is a mechanical device consisting of a coil, a casing, and a plunger that may move. When an electrical current is applied to the coil, a magnetic field is created around it, pulling the plunger closer. A Solenoid is a device that transforms electrical energy into mechanical work.

Construction
Construction of Solenoid Valve

  • Several rounds of coiled copper wire are used in making the coil. When an electrical current is sent through this wire, a significant magnetic field/flux is produced in the surrounding area.

  • The coil is enclosed inside a housing, often constructed of iron or steel, which concentrates the magnetic field produced by the coil.

  • The plunger is drawn to the stop by the concentration of the magnetic field. The field provides the mechanical force necessary to complete the task.

Precautions before installing the Solenoid

  • The product will include a liquid that will be compressed. It is not a safety device. It should not be used as the only device to prevent the over-pressure of certain plant sections. Improper use could be dangerous and cause damage to people and property.

  • Before beginning the installation, startup, and maintenance process, review the manufacturer's instructions.

  • Before installation, double-check the operating conditions. It is listed on the product label and technical documentation.

  • Keep in mind the flow direction indicated by an arrow on the valve body. For 2-way valves, the flow is from port 1. For 3-way valves, the flow is from port 2, etc. Valves with an arrow engraved on the body can only work in that direction.

  • As a precaution, check to see that there is no pressure inside the tubing. Or within the valve itself before disconnecting or disassembling it.

  • The fixing holes, if any, on the valve body and any other part of the valve body must not be modified.
  • During the assembly process, you should take extra care.

  • On the valve threads, use a seal material that is appropriate for the application. In installations where liquid cement is used, it is critical to prevent the cement from entering the valve.

  • The pilot-operated solenoid valve circuit should not have its holes closed off.

  • It is not recommended to activate the coil before it is placed on the valve. Or before the armature assembly is installed within the valve since this may cause it to burn out or break.

  • Do not use any spare parts other than those supplied by the manufacturer.

  • Do not exceed the manufacturer’s pressure, temperature, and voltage limitations. They are shown on the product label and the accompanying technical documentation.

  • Neither the valve nor the coil should have their labels removed.

  • Before installing and starting the valve, ensure that the fluid and the valve's material are compatible.

  • Always connect the earth connection of the coil to the ground. Do not use the tubes to transfer fluids to or from electrical equipment connected to the earth.

Maintenance of Solenoids

  • Cleaning the internal parts of the valve while it is disassembled.

  • Remove all dirt and dust from the components before reassembling them.

  • When purchasing spare parts, Always see the model and code of the valve and the date code.

Recommendations for Installing a Solenoid

  • Before beginning the installation and startup process, read and follow the manufacturer's instructions.
  • You can operate the valve in any of its operating positions. It is recommended that the valve be installed vertically.

  • Rotate a coil on its axis by loosening the coil nut and tightening it again.

  • During operating, the coil temperature is often higher than at rest. Smoke and the smell of burning will be produced as a result of irregular overheating. In this case, you must turn the power supply off immediately.

  • Install the valve away from heat sources and in a location where the coil generates the heat.

  • It is critical to adhere to the flow direction, the pressure, and the technical data on the label when using this product.
