▶Actuated via proportional solenoids with central thread and removable coil
▶Spring centred control spool
Application:
Three-way proportional pressure reducing valve 3DREP 6A is widely used in industrial fields, mobile mechanical hydraulic systems, workbenches and other high-end equipment.
Function and Valve Particularities of Proportional Pressure Reducing Valve 3DREP 6A
The 3-way pressure reducing valve type 3DREP 6. is directly actuated by proportional solenoids. They convert an electrical input signal into a proportional pressure output signal.
The proportional solenoids are controlable wet pin DC solenoids with central thread and removable coil. The solenoids are controlled optionally via external control electronics.
◆Design:
The valve mainly comprises of:
Housing (3) with mounting surface
Control spool (5) and(6) and (4)
Solenoids(1 and 2 ) with control thread
◆Function:
With the solenoids (1 and 2) de-energised the control spool (5) is held in its centre position by compression springs.
The control spool (2) is directly actuated when one of the solenoids is energised.
E.g. by energising solenoid "a" (1)
→The pressure measuring spool (5) and control spool(4) move to the right in proportion to the electrical input signal.
→The connection from P to B and A to T is via orifice form cross-sections with progressive flow characteristics
◆De-energisation of the solenoid (1)
→The control spool (4) is returned to its centre position by the compression springs
In the middle position the connections A and B to T are open, therefore, the pressure fluid can freely flow to tank. An optional hand overrides makes is possible to move the control spool (4) without energising the solenoid.
●Attention!
Unintended use of the hand override can cause uncontrolled machine movement!
