The control valve is a tool that directs the fluid to the actuator. This tool will include cast iron or steel spool which is positioned within a housing. The spool slides to various positions in the housing. Intersecting channels and grooves route the fluid based on the spool's position.
The spool is centrally positioned, help in place with springs. In this particular location, the supply fluid could be blocked and returned to the tank. If the spool is slid to one direction, the hydraulic fluid is directed to an actuator and provides a return path from the actuator to tank. If the spool is transferred to the opposite side, the supply and return paths are switched. As soon as the spool is allowed to return to the neutral or center position, the actuator fluid paths become blocked, locking it into position.
Usually, directional control valves are built so as to be stackable. They generally have one valve for each and every hydraulic cylinder and a fluid input which supplies all the valves inside the stack.
So as to prevent leaking and handle the high pressure, tolerances are maintained really tight. Normally, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. To be able to prevent distorting the valve block and jamming the valve's extremely sensitive components, the valve block would be mounted to the machine' frame with a 3-point pattern.
Mechanical levers, solenoids or a hydraulic pilot pressure may actuate or push the spool left or right. A seal allows a part of the spool to protrude outside the housing where it is accessible to the actuator.
The main valve block controls the stack of directional control valves by capacity and flow performance. Some of these valves are designed to be proportional, as a valve position to the proportional flow rate, whereas other valves are designed to be on-off. The control valve is among the most sensitive and expensive parts of a hydraulic circuit.
Counterbalance lift trucks are popular pieces of machinery in the material handling trade. They are really common machines used in warehouses and factories around the globe. The leading forklift producers like Toyota, Mitsubishi and Linde all create counterbalance forklifts. They are accessible in a variety of fuel alternatives like for example electric, gas or diesel. Normally, a counterbalanced forklift truck contains the following components:
The Cab is the part which has a seat for the individual operating ti and houses the control pedals, levers, steering wheel, a dashboard containing operator readouts and different switches. The Truck Frame is the foundation of the machine that each of the other parts, mast and counterweight, the axles, wheels, power source are all attached to. The frame could likewise have fuel tanks and hydraulic fuel tanks constructed as part of its assembly. The Mast is the vertical assembly that does most of the work raising and lowering the forklift's load.
The counterweight is a heavy mass of cast iron which is connected to the back of the forklift truck frame. The counterweights' objective is to balance all the cargo being carried. Using an electric forklift, the big lead-acid battery itself can work as part of or all of the counterbalance. The Power Supply could have an internal combustion engine which can be powered by diesel, gasoline, LP gas or CNG gas. Electric lift trucks are powered by either fuel cells which provide power to a battery or electric motors. The electric motors could be either AC or DC types.
Fork accessories are various kinds of material handling attachments that are presented consisting of container handlers, carpet poles, pole handlers, side shifters, multipurpose clams, carton clamps, slip-sheet attachments, fork positioners and roll clamps.
The counterbalanced lift truck is the ideal electric lift truck to use for parking pallets closely all together. Counterbalanced lift trucks provide several advantages over straddle-leg styles and fork-over designs. They do have a few drawbacks though. A counterbalanced forklift can carry pallets straight off the floor as there are no stabilization legs to get in the way. The main disadvantage of this particular model of forklift is that the lift height and the weight capacity will normally be less than the different styles.
