VSD03M - SOLENOID OPERATED DIRECTIONAL VALVES
APPLICATION DATA
FLUIDS
All pressure drops shown on these data pages are based on 170 SUS uid viscosity and 0.87 specic gravity.
For any other specic gravity (G1) the pressure drop (∆P) will be approx. ∆P1= ∆P (G1/G). See the chart for
other viscosities.
Use mineral oil-based hydraulic uids HL or HM type, according to ISO 6743-4. For these uids, use NBR
seals. For uids HFDR type (phosphate esters) use FPM seals (code G). For the use of other kinds of uid
such as HFA, HFB, HFC, please consult our technical department.
Using uids at temperatures higher than 180 degrees F causes the accelerated degradation of seals as well
as degradation of the uids physical and chemical properties.
From a safety standpoint, temperatures above 130 degrees F are not recommended.

INSTALLATION
Valves with centering and return springs can be mounted in any position without impairing correct operation.
Valves with mechanical detent should have horizontal mounting.
Valves are xed by means of screws or tie rods on a at surface with planarity and roughness equal to or
better than those indicated in the relative symbols. If minimum values are not observed, uid can easily leak
between the valve and support surface.
