SALAMI VDM6/DD/U4S

Description & Features

The SALAMI VDM6/DD/U4S is a high-performance monoblock valve designed for industrial applications. With cast-iron monoblock construction and capacity for up to 7 spools, it ensures reliable function under challenging conditions.

This valve features a parallel circuit with load check valve protection and a tandem circuit available on the first spool. It offers a venting valve and power beyond capability, providing flexibility in hydraulic system design.

Crafted with hardened steel, nickel-plated spools, it enhances surface hardness and corrosion resistance. The variety of spool types and control devices enable customization to meet specific requirements. The minimum tolerance between the spool and body minimizes internal leakage.

Operating efficiently in ambient temperatures ranging from -22deg;F to 140deg;F and fluid viscosities from 10 to 400 cSt, the SALAMI VDM6/DD/U4S achieves optimal performance within a fluid viscosity range of 12 to 75 cSt. It can withstand a maximum operating pressure of 5100 PSI on ports "P", "A", and "B" and maximum back pressure of 363 PSI.

Recommended filtration meets ISO 4406: 19/16 standards. The internal leakage rate ranges from 1.1 to 1.52 insup3;/min at 2285 PSI, ensuring efficient hydraulic system performance.

Question by: Frank C on Feb 23, 2026, 12:51 PM

running this on a small log splitter setup, what's the max pressure i can push through it before something gives?

Answer by: Customer Support on Feb 24, 2026, 4:49 PM

Port ratings on the P, A, and B lines top out at 5100 PSI, which is a solid ceiling for most light-to-mid-duty hydraulic work. Back pressure on the return side is capped at 363 PSI, so make sure your return line isn't restricted. For a log splitter application, you've got plenty of headroom on the pressure side as long as your pump and lines are sized to match.

got a 12 gpm pump on my rig, is this valve gonna be the choke point?

Answer by: Customer Support on May 4, 2025, 7:02 AM

With a 12 GPM flow rating, it is sized to handle that pump flow. Keep in mind it also has a maximum back pressure rating of 363 PSI, so return line restrictions and downstream hydraulic connections still matter for overall performance.

Question by: Diane L on Jan 25, 2026, 7:37 PM

Will this handle typical hydraulic fluid okay, or do I need to use somethin' special?

Answer by: Customer Support on Jan 27, 2026, 8:51 AM

It's designed for fluid viscosities between 10 and 400 cSt, but it works best if you keep it in the 12 to 75 cSt range. Regular hydraulic fluid should be just fine, but keep an eye on your temps.

Question by: Hubert L on May 28, 2025, 6:21 PM

got a compact power unit that runs about 12 gpm. is this VDM6 valve sized right for that flow?

Answer by: Customer Support on May 30, 2025, 6:35 AM

For flow, it lines up. The VDM6 series is rated at 12 GPM, so a 12 GPM system is within what it is built to handle.

Question by: Howard E on Jul 8, 2025, 5:38 PM

What kind of fluid should I be using in this valve? I've got some different weights laying around.

Answer by: Customer Support on Jul 9, 2025, 7:19 PM

Optimal performance for this valve is going to be when you're running a fluid viscosity between 12 and 75 cSt. It can handle a range from 10 to 400 cSt, but that's where you'll see the best results.

Question by: Rusty W on Aug 9, 2025, 6:12 AM

Running this on a piece of equipment that sees some pretty nasty temperature swings. What's the actual operating range on this valve?

Answer by: Customer Support on Aug 10, 2025, 9:57 PM

Ambient temps between -22°F and 140°F are within spec for this valve. Fluid temperature range with NBR seals goes from -4°F up to 185°F. So as long as your setup stays inside those windows, you're in good shape. Just keep in mind that all the technical data was developed using mineral oil at 16 cSt viscosity, so if your fluid runs real thick or real thin, performance can shift. Optimal viscosity range is 12 to 75 cSt, though the valve tolerates anywhere from 10 to 400 cSt.
