EDC-LV

Valve element with direct proportional flow sharing control.

It can achieve the simultaneous activation of different actuators by distributing the available flow proportionally to the speeds selected by the operator. All simultaneous movements go on at the same reciprocal speed also in case of flow shortage.

No shuttle valve fitted.

Control spools manual operated by hand lever. Control spool with return for all three positions.

Size 6

Series 00

Maximum operating pressure on "P" 350 bar (5076 psi)

Maximum peak pressure "A-B" 380 bar (5511 psi)

Maximum flow at 14 bar (203 psi) 70l/min(18.49gpm)

Maximum flow at 18 bar (261 psi) 78l/min(20.6gpm)

Ports connections planned G 3/8 - G 1/2 - SAE8 and Modular

The sandwich plate design directional valve elements L85L1... are compact direct operated pressure compensated manual operated valves which control the start, the stop, the direction and the quantity of the flow, with a FLOW SHARING principle.

These elements basically consist of a stackable housing (1) with the control spool (2), a block with the control lever (3), and a spring housing (4) with a return spring.

When the hand operated lever moves the control spool (2) from its neutral-central position "0" and the metering notches are open; flow is delivered to the 3 way pressure compensator (5) followed by a check valve (6) for each port A or B.

The compensator, balanced by the LS pressure at the opposite and, lifts up and unloads a pressure compensated flow which is sent to the A (or B) port through the relevant check valve; at the same time the opposite port allows oil return to tank.

LS pressure reaches the compensator "dead end" directly from the A or B port, while the check valves lock eventual pressure oscillations which could affect the compensator function.

Type L85L1_2 M1_000 is the valve version in which the spring return brings the spool back to neutral-central position "0"when the manual lever is not operated.
