HKSV100 directional control valve group is commonly used for mini excavators, compact front loaders, cranes, backhoe loaders.
Sectional valves stated in other words sectional directional control valves are highly flexible and have various auxiliary valves such as anti-shock, anti-cavitation, electro hydraulic pilot operated unloader, hydraulic pilot unloader etc. Generally sectional valves have check valve for each work section are from 1 to 12 sections with open center, closed center hydraulic circuits. Various sections used together such as series, parallel or tandem circuit valve. Also sectional valves may have intermediate pump and tank sections.
Between two sections it is possible to add pressure or flow compensator. As described above Sectional valves have various options when compared to monoblock valves. However there are some disadvantages of the sectional valves is lower working pressure when compared to monoblock valves. Sectional valves maximum working pressure should be 320 bar. Total sizes of the sectional valves are not as compact as monoblock valves, some space limited applications do not prefer big valves as sectional valves.
In the intricate world of hydraulic control systems, the sectional valve stands as a modular powerhouse, offering precision and flexibility. This article explores the fundamental aspects of sectional valves, shedding light on their design, functionality, applications, and the crucial role they play in optimizing hydraulic operations across various industries.
A sectional valve, also known as a sectional directional control valve, is a versatile hydraulic component designed to control the flow of hydraulic fluid in a modular and customizable manner. Unlike monoblock valves, sectional valves consist of individual sections or modules that can be assembled to create a tailored hydraulic control system.
Sectional valves feature a modular construction, with each section dedicated to a specific hydraulic function. These sections can be combined or stacked according to the requirements of the hydraulic system, allowing for a high degree of customization.
Similar to monoblock valves, sectional valves often employ a spool valve mechanism. The movement of the spool within each section controls the flow of hydraulic fluid, determining the direction and function of the hydraulic system.
Sectional valves primarily serve as directional control valves, regulating the flow of hydraulic fluid to different components of the hydraulic system. They enable precise control over the movement of hydraulic actuators such as cylinders and motors.
Sectional valves come with various functionalities, allowing for the creation of complex hydraulic systems. These include three-position, four-way valves for controlling double-acting cylinders and two-position, three-way valves for controlling single-acting cylinders.
Sectional valves find extensive use in mobile hydraulic applications, such as those in construction, agriculture, and forestry machinery. Their modular design allows for the creation of customized control systems tailored to the specific needs of mobile equipment.
In industrial settings, sectional valves contribute to the operation of various machines, including presses, injection molding equipment, and material handling systems. Their modular nature enables precise control over diverse hydraulic functions.
Sectional valves play a role in the oil and gas industry, where they are utilized in hydraulic systems for drilling rigs, wellhead control, and other critical applications that demand reliability and precision.
The modular design of sectional valves provides unparalleled customization and flexibility. System designers can assemble and arrange valve sections to meet the specific requirements of the hydraulic system.
The modular nature of sectional valves simplifies maintenance. If a particular section requires attention or replacement, it can be addressed without affecting the entire hydraulic system, minimizing downtime.
Sectional valves offer scalability, allowing hydraulic systems to be easily expanded or modified. Additional sections can be added to accommodate new functions or changes in system requirements.
In conclusion, sectional valves emerge as key contributors to the precision and flexibility of hydraulic control systems. Their modular design, customizable functionalities, and adaptability make them essential components in various industries, driving efficiency and control in hydraulic operations. Understanding the design, functionalities, and advantages of sectional valves is pivotal for harnessing their capabilities and optimizing hydraulic systems in the dynamic landscape of industrial technology.
