Hydraulic cylinder with valve

Valve in Cylinder is a Hydraulic Actuator that integrates Hydraulic Valve groups (such as directional valves, throttle valves, balance valves, etc.) directly inside or near the cylinder.

1. Main types

**(1) Classified by valve group position**

|* * Type * * | * * Characteristics * *|

|-------------------|--------------------------------------------------------------------------|

|* * Built in * * | The valve group is directly integrated inside the oil cylinder, with the most compact structure, but maintenance is more complex.                       |

|The bypass type valve group is installed on the side or end cover of the oil cylinder for easy maintenance and occupies slightly more space.                       |

|* * Flanged * * | The valve group is connected to the oil cylinder through a flange and is suitable for high flow and high pressure systems.                       |

**(2) Classified by valve group function**

-* * Directional Valve cylinder * *: Integrated electromagnetic directional valve, controlling the expansion and contraction of the cylinder (such as two position four-way, three position four-way).   

-Balance valve cylinder: prevents sudden drop of load (such as cranes, lifting platforms).   

-Proportional valve cylinder: Integrated proportional directional valve, achieving precise control of speed and position.   

-* * Servo valve cylinder * *: used for high-precision closed-loop control (such as injection molding machines, testing machines).   

2. Typical technical parameters

|* * Parameter * * | * * Typical Range * *|

|------------------|--------------------------------------|

|* * Cylinder diameter/rod diameter * * | Φ 40mm~Φ 250mm (customizable)|

|* * Travel * * | 50mm~3000mm|

|* * Work pressure * * | 16MPa~35MPa (high pressure type can reach 70MPa)|

|* * Flow rate * * | 20L/min~100L/min (depending on valve group specifications)|

|* * Control voltage * * | DC12V/24V, AC220V (applicable to solenoid valves)|

|* * Protection level * * | IP65 (dustproof and waterproof)|

|* * Valve type * * | Electromagnetic directional valve, proportional valve, servo valve, etc|
