## Summary description

Retention valve MT 4119-020 is a hydraulic retention/check valve designed to maintain fluid position and prevent backflow in hydraulic systems. Supplied by MT with part number 4119-020, it is used in circuits where holding pressure or preventing reverse flow is required, such as mobile machinery, industrial hydraulics, and actuator locking applications.

## Long description

Retention valve MT 4119-020 is a hydraulic check/retention valve designed to maintain fluid position and prevent backflow in hydraulic circuits. Manufactured by MT, this valve holds actuator position and prevents unintended reverse movement by allowing flow in one direction and locking fluid in the other. The compact design enables integration into mobile machinery, industrial hydraulic systems and actuator circuits where secure holding and backflow prevention are required.
Advantages
The valve provides reliable retention of hydraulic pressure to maintain cylinder or motor position without continuous external control. Its one-way flow characteristic prevents reverse flow and protects system components from unwanted motion. The device is suitable for installation in tight spaces and integrates with standard hydraulic lines, offering consistent performance under varying load conditions.
Suitable for
Mobile machinery hydraulic circuits
Industrial hydraulic systems requiring actuator lock
Lift and lowering control to prevent reverse movement
Holding loads in cylinders or hydraulic motors
Key specifications
Function: hydraulic retention/check valve for one-way flow and pressure holding
Application: actuator locking, load holding, backflow prevention
Installation: in-line mounting with hydraulic fittings (compatible with standard hydraulic lines)
Compatibility: suitable for mobile and industrial hydraulic fluids within typical system pressure ranges
Design: compact, suitable for confined installation spaces
How to use
Install the retention valve in the hydraulic line according to the flow direction indicated on the valve body so that it permits desired forward flow and prevents return flow. Ensure connections are tightened to appropriate torque and that sealing surfaces and fittings match system requirements. After installation, slowly pressurize the system and inspect for leaks; verify that the valve holds pressure and prevents reverse movement of the actuator under expected load conditions.
Usage recommendations
Use clean hydraulic fluid and appropriate filtration to reduce contamination risk. Verify system pressure compatibility before installation and perform periodic inspections for leaks or wear. When integrating into safety-critical circuits, follow the machine manufacturer’s guidelines and applicable standards for hydraulic locking devices.
