The directional control valve in a hydraulic system is very powerful than any pneumatic system as they operate at high pressure. Due to this, the hydraulic DCV is more vigorous and robust. So the machine is manufactured from high quality and strengthened material.
Ports and switching positions
The most vital part of choosing a hydraulic directional control valve is the number of ports and switching positions. There are three standard measurements for it. That is, two-way-two-position, four-way-four-position, and four-way-three-positions. The ports are responsible for the connection of the system, and representing it is using single letters. The switching positions are responsible for the flow inside the system.
Technical requirements that matters
To achieve the whole purpose of a directional control valve, taking good care of specifications like PSI (Pounds per Square Inch) and GPM (Gallons per minute) is vital. The DCVs come in various pressures and GPMs. Always opt for the correct pressure depending upon the requirements. Choosing the wrong pressured valves may have a crucial impact on operating power.
Number of spools to consider
The number of spools is not always standard. There are three spools DCV available. However, there are eight spools DCV available too. So choose wisely the number of spools your machine should contain. Other general specifications include the material of the DCV, which is mostly cast iron. The operation of the valves may include double-acting. Also, spring return makes the spool return to its original position automatically.
Other important things to ponder
The connector type, handle type, and the style of the design also to be considered when buying a hydraulic directional control valve. Look for the maximum temperature it can tolerate when placing it in hot environments. Fulfilling these factors will help the hydraulic directional control valve to last longer than usual.
