EATON VICKERS DGMFN-3-Y-A2W-B2W-41 531516

Eaton Vickers DGMFN-3 SystemStak Hydraulic Flow Control Valve

Description

The Eaton Vickers DGMFN-3-Y-A2W-B2W-41 is a high-performance modular flow control valve designed for precise speed control in hydraulic circuits. As part of the renowned SystemStak series, this valve mounts directly between a directional valve and a subplate or manifold (sandwich design), saving space and reducing potential leak points. It provides dual flow control on the A and B ports, allowing for independent adjustment of actuator speed in both directions. Its rugged construction ensures reliability in demanding industrial environments.

FAQ

What is the function of the ‘A2W’ and ‘B2W’ designations in the model number?

The ‘A2W’ and ‘B2W’ codes specify the type of flow control for the A and B hydraulic ports, respectively. In this model, it indicates dual meter-in or meter-out control with a specific type of screw adjustment (‘W’). This allows for independent speed control of a hydraulic actuator in both directions of movement.

What type of hydraulic fluid is compatible with this DGMFN-3 valve?

This valve is typically compatible with standard mineral oil-based hydraulic fluids (like HL, HLP) and some synthetic fluids. It’s crucial to check the seal material compatibility if using non-standard fluids. For this design series, NBR (Nitrile) seals are standard.

What are the recommended mounting bolt torque specifications for a CETOP 3 / NG6 valve like this?

For a standard CETOP 3 (NG6) interface with grade 10.9 bolts (typically M5), the recommended tightening torque is generally between 6.5 and 7.5 Newton-meters (Nm). Overtightening can warp the valve body, while under-tightening can lead to leaks. Always ensure the mounting surface is clean and flat.
