4/2 way isolator valve- Type Z4WE6...L3X
Features
– Solenoid operated directional spool valve is the standard version
– Porting pattern to DIN 24 340 form A, ISO 4401 and CETOP–RP 121 H
– Free-flow through ports P and T in all switched positions
– Sandwich plate valve
– Wet pin AC or DC solenoids
– Hand override, (optional)
Function and configuration
Type Z4WE6 Isolator valves are solenoid operated directional spool valves. They control the flow connection and isolating of flow.
Essentially the directional control valves consist of housing (1), one or two solenoids (2), the control spool (3), and two return springs (4).
In the de-energized condition the control spool (3) is held in the neutral or initial position by means of return springs (4) (except for pulse valves). The control spool (3) is actuated via wet pin solenoids (2).
To ensure satisfactory operation care should be taken that the solenoid pressure chamber is filled with oil.
The force of the solenoids (2) acts via the push rod (5) on the control spool (3), control spool (3) is pushed from its neutral position to the required position. Then port A1, A2, B1 and B2 can be either connected or disconnected. P and T always flow freely.
When solenoid (2) is de-energized, the control spool (3) is returned to its neutral position by means of the return springs (4).
An optional hand override allows movement of the control spool without energizing the solenoid.
