Description & Features

The Salami VDM8/DDDD/U4S monoblock valve is engineered for superior performance with a cast-iron construction capable of accommodating up to five spools. Utilizing a parallel circuit and load check valve protection this component ensures optimal functionality under challenging conditions.

Built with hardened steel nickel-plated spools the valve attains higher surface hardness and offers corrosion resistance. A variety of spool types and control devices are available enhancing customization for specific applications.

The design incorporates venting valve and power-beyond features catering to diverse operational needs. With minimum tolerance between the spool and body the valve achieves minimal internal leakage ranging between 1.52 to 2.13 in/min at 2285 PSI.

Designed for an ambient temperature range of -22F to 140F and fluid viscosity between 10 to 400 cSt with optimal operation between 12 to 75 cSt. The valve supports a maximum back pressure of 363 PSI and operates effectively at up to 5100 PSI on ports "P" "A" and "B".

Auxiliary valves are available for ports A and B providing additional versatility. Recommended filtration follows ISO 4406: 19/16 standards ensuring optimal fluid purity.

Question by: Brett H on Oct 18, 2025, 12:25 PM
what's the internal leakage like on this valve? running a pretty tight system and can't afford much slop
Answer by: Customer Support on Oct 20, 2025, 12:16 PM
At 2285 PSI, internal leakage runs between 1.52 and 2.13 cubic inches per minute. That's a result of the minimum tolerance machined between the spool and body, which Salami holds pretty close on this series. The hardened, nickel-plated spools also help maintain that fit over time compared to softer materials that can wear and open up clearances faster.
Question by: Bonnie P on Sep 29, 2025, 3:40 PM
What kind of temperatures can this valve handle, operating and storage wise?
Answer by: Customer Support on Sep 30, 2025, 9:46 PM
This valve is designed to work in ambient temperatures from -22°F to 140°F. For optimal performance with NBR seals, keep the temperature between -4° and 185°F.
