The control valve is a tool which routes the fluid to the actuator. This tool would comprise steel or cast iron spool that is located inside of housing. The spool slides to different locations in the housing. Intersecting channels and grooves route the fluid based on the spool's position.
The spool is centrally positioned, help in place by springs. In this particular position, the supply fluid can be blocked and returned to the tank. If the spool is slid to a direction, the hydraulic fluid is routed to an actuator and provides a return path from the actuator to tank. If the spool is moved to the other side, the return and supply paths are switched. Once the spool is allowed to return to the center or neutral location, the actuator fluid paths become blocked, locking it into place.
The directional control is usually intended to be stackable. They usually have one valve for every hydraulic cylinder and one fluid input which supplies all the valves in the stack.
In order to prevent leaking and handle the high pressure, tolerances are maintained really tight. Usually, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. In order to prevent jamming the valve's extremely sensitive components and distorting the valve, the valve block would be mounted to the machine' frame by a 3-point pattern.
The position of the spool could be actuated by hydraulic pilot pressure, mechanical levers, or solenoids that push the spool left or right. A seal enables a portion of the spool to protrude outside the housing where it is accessible to the actuator.
The main valve block is usually a stack of off the shelf directional control valves chosen by flow performance and capacity. Various valves are designed to be on-off, while some are designed to be proportional, like in valve position to flow rate proportional. The control valve is amongst the most sensitive and pricey parts of a hydraulic circuit.
In the material handling business counterbalance lift trucks are very popular pieces of machinery. They can be normally used in warehouses and factories all around the world. The leading forklift producers such as Toyota, Mitsubishi and Linde all create counterbalance lift trucks. They are presented in various fuel choices such as diesel, electric or gas. Usually, a counterbalanced forklift truck includes the following components:
The part meant for the operator known as the "cab" and houses all of the pedals, steering wheel, a dashboard which contains certain readouts, levers plus a variety of switches. The frame of the lift truck is the foundation utilized for the various components of the machinery comprising the power supply, the wheels, the axles, mast and the counterweight. The frame can also have hydraulic fluid tanks and fuel tanks constructed as part of its assembly. The Mast is the vertical assembly that does the majority of the work lowering and raising the forklift's load.
Made of heavy iron the counterweight is connected to the rear of the forklift frame. The purpose of the counterweight is to counterbalance the cargo being carried and transported. Utilizing an electric forklift, the huge lead-acid battery itself can function as part of or all of the counterweight. The Power Source may have an internal combustion engine that can be powered by gasoline, LP gas, CNG gas or diesel. Electric lift trucks are powered by either fuel cells that provide power to electric motors or a battery. The electric motors could be either AC or DC kinds.
Fork attachments are various types of material handling attachments that are offered including roll clamps, container handlers, carpet poles, pole handlers, side shifters, multipurpose clams, carton clamps, slip-sheet attachments and fork positioners.
When needing to park pallets closely together, the counterbalance forklift is the best electric lift used for the job. There are numerous advantages to using a counterbalance lift instead of fork-over and straddle-leg designs. They do have several drawbacks though. A counterbalanced lift truck can carry pallets directly off the ground since there are no stabilization legs to interfere. The main disadvantage of this model of forklift is that the lift height and the weight capacity will normally be less than the different styles.
