Редукционный клапан прямого действия DR 10 DP

Description Size 10 Component series 4X Maximum operating pressure 210 bar Maximum flow 80 l/min Features For subplate mounting Porting pattern according to ISO 5781-06-07-0-00 4 optional adjustment types: • Rotary knob • Threaded pin with hexagon and protective cap • Lockable rotary knob with scale • Rotary knob with scale 4 pressure ratings With pressure gauge connection Check valve, optional Corrosion-protected design Product description The valve type DR 10 DP is a direct operated pressure reducing valve in 3-way version, i. e. with pressure limitation of the secondary circuit. It is used to reduce a system pressure. The secondary pressure is set via the adjustment type (1). The valve is open in initial position. Hydraulic fluid can flow from channel B to channel A without restrictions. The pressure in channel A is simultaneously applied via the control line (4) at the piston area opposite the compression spring (3). If the pressure in channel A exceeds the value set at the compression spring (3), the control spool (2) moves into control position and keeps the set pressure in channel A at a constant level. Signal and pilot oil are supplied internally via the control line (4) from channel A. If the pressure in channel A increases further due to an external force effect at the actuator, it pushes the control spool (2) even further against the compression spring (3). In this way, channel A is connected to the channel T(Y) via the control edge (5) at the control spool (2). Hydraulic fluid is discharged into the tank to an extent that the pressure can only slightly increase. The leakage oil discharge from the spring chamber (6) is always effected externally via channel T(Y). For the free flow back from channel A to channel B, a check valve (7) can optionally be installed. A pressure gauge connection (8) allows for the control of the secondary pressure.
