How does it accomplish this? This is achieved by controlling the speed, pressure, and direction of flow of hydraulic fluid in the control system piping. Well, We can say that hydraulic valves are components of the most functional categories, with the widest range of applications, and are the most active components in hydraulic systems. The mature design and functional operation of hydraulic systems largely depend on the stable quality of the hydraulic valve and function matching. <span style=\"font-size: 16px;\">So how many types of hydraulic valves?<\/span><\/p>\n<h1><span style=\"font-weight: 400;\">Types of\u00a0 Hydraulic Valve\u00a0<\/span><\/h1>\n<h2><span style=\"font-weight: 400;\">Main classification:<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Hydraulic valves mainly includes directional control valves, pressure control valves and flow control valves.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. <a href=\"\/hydraulic-valve\/directional-control-valve\/\">Directional control valves<\/a>\uff1a<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">These include check valves and directional valves. Check valves allow unidirectional flow of fluid, while directional valves control such as the solenoid valve, the opening and closing of the oil circuit and the direction of oil flow by changing the relative position between the spool and the valve body.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. <a href=\"\/hydraulic-valve\/pressure-control-valve\/\">Pressure control valves<\/a>:\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Used to regulate pressure, they include relief valves, sequence valves, pressure-reducing valves, etc. Relief valves are used to control the hydraulic system to maintain a constant state when the set pressure is reached, while sequence valves are used to control the sequence of pressures in the hydraulic system.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3.<a href=\"\/hydraulic-valve\/flow-control-valve\/\"> Flow control valves<\/a>:\u00a0<\/span><\/h3>\n<p><span style=\"font-weight:

Other Ways to classify hydraulic valves<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">By the methods of valve mounting, there are Pipe mounting valve, sectional valve, subplate valve, sandwich valve,and thread connection(cartridge) valve.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By the control signal type, it can be divided into manual, electric control, and liquid(pilot) control.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By the principle of operation, it is divided into switching valves, servo valves, proportional valves, and logic valves.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By the structure, it can be divided into spool valve, rotary valve, seat valve\uff08ball and poppet), jet pipe valve, etc.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Next we&#8217;ll go into more detail about Pipe mounting valve, sectional valve subplate valve, sandwich valve and thread

Threaded cartridge valves and their integrated blocks account for more than 25% of the global hydraulic valve sales.<\/p>\n<p>In mobile hydraulics, due to traditional reasons, directional control valves with sectional designs are still quite prevalent. These include manual, hydraulic, and electric controls. Even when electric controls are adopted, manual handles are often retained as an emergency measure in case of failure.<\/p>\n<p>Other controls use integrated blocks with threaded cartridge valves. The application of forged tube core components with single functions is also decreasing. Even if pipe connections are necessary due to various reasons, threaded cartridge valve groups are often used to form valve blocks with pipe connections.<\/p>\n<p>References<\/p>\n<p><span style=\"font-weight: 400;\">[1] Hai Ping Zhang, &#8220;Hydraulic Threaded Cartridge Valves,&#8221; China Machine Press, 2011.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">[2] John J.
