NOTE: with positive reference signal connected to pin D the valve regulates P - A / B - T. The diagram states the maximum valve controlled ﬂow rate according to the pressure drop between the P and T ports. PRESSURE GAIN (LZ) The diagram shows the valve pressure gain, expressed as % of the ratio between the port pressure variation in A or B (∆p AB) and the P system pressure, according to the reference signal. In practice, the pressure gain states the valve reaction towards external disturbances aimed at changing the actuator position.

The Monitor signal output is referenced between Pin F and Pin B. OBW version is programmed for Internal enable, power for enable is taken directly from the power supply. The power to the valve must be turned off to disable the valve. The Monitor signal output is referenced between Pin F and Pin B. OBM version is programmed for Internal enable, power for enable is taken directly from the power supply. The power to the valve must be turned off to disable the valve. The Monitor signal output is reference between Pin F and Pin C for PIN to Pin interchangeability with other manufacturers.

For these ﬂuids, use NBR seals. For ﬂuids HFDR type (phosphate esters) use FPM seals (code G). For the use of other kinds of ﬂuid such as HFA, HFB, HFC, please consult our technical department. Using ﬂuids at temperatures higher than 180 degrees F causes the accelerated degradation of seals as well as degradation of the ﬂuids physical and chemical properties. From a safety standpoint, temperatures above 130 degrees F are not recommended. INSTALLATION VED03MX - HIGH PERFORMANCE, SERVO-PROPORTIONAL DIRECTIONAL CONTROL VALVE FLUIDS All pressure drops shown on these data pages are based on 170 SUS ﬂuid viscosity and 0.87 speciﬁc gravity. For any other speciﬁc gravity (G1) the pressure drop (∆P) will be approx. ∆P1 = ∆P (G1/G). See the chart for other viscosities. VED03MX valves can be installed in any position without impairing correct operation. Ensure that there is no air in the hydraulic circuit. Reference page 5. Valves are ﬁxed by means of screws or tie rods on a ﬂat surface with planarity and roughness equal to or better than those indicated in the relative symbols. If minimum values are not observed, ﬂuid can easily leak between the valve and support surface. 7 PIN PLUG VEA-3P7P-A Straight plug 7-pin plastic housing 264893 VEA-3P7M-A Straight plug 7-pin metal housing 265947 Valve only 1008406 BOLT KIT BD03-125 NOTES: 1.
