Functional, section
The valve type DR 6 DP is a 3-way direct operated pressure reducing valve with a pressure relief function on the secondary side.
It is used to reduce the system pressure. The secondary pressure is set by the pressure adjustment element (4).
At rest, the valve is normally open and the pressure fluid can flow unhindered from port P to port A The pressure in port A is at the same time, via the control line (6), present al the spool area opposite to the compression spring (3).
When the pressure in pod A exceeds the pressure level set at compression spring (3). the control spool (2) moves into the control position and holds the set pressure in port A constant.
The control and pilot oil are taken from port A via control line (6)
If the pressure in port A still increases due to external forces on the actuator, the control spool (2) moves still further towards the compression spring (3).
This causes a flow path to be opened at port A via control land (8) on the control spool (2) to the tank. Sufficient pressure fluid then flows to tank to prevent any further rise in pressure.
The spring chamber (7) is always drained to tank externally via port T (Y).
For free return flow from port A to port P an optional check valve (5) can be fitted
A pressure gauge connection (1), permits the secondary pressure at the valve to be monitored
Unit dimensions: type DR6DP (Dimensions in mm)
The product shows a promising application prospect due to its practicality.
