PRESSURE REDUCING VALVES General Information Fluid:best use mineral oil with viscosity ranging between 10 and 200 cSt. Filter:dirty oil is the main reason for failure and troubles of hydraulic parts and systems. The table below contains OLEOSTAR S.p.A. recommendations about the minimum oil contamination level according to individual specifications of different items. For further safety of your hydraulic equipment and of all valves assembled on it, we either recommend use suction filters (rather than return filters) or separated filter lines.
TYPE OF EQUIPMENT - TYPE OF VALVE
CONTAMINATION LEVEL According to ISO 4406
- Heavy duty equipment - Equipment running at 210-350 bar (3050-5100 psi) working pressure - Equipment using proportional controls - Equipment with high frequency cycles
-/16/13
- Equipment running up to 210 bar (3050 psi) working pressure - Spool-type valves - Valves with calibrated ports
-/18/14
- Equipment running at low working pressure - Pilot plants and equipment - Equipment with low frequency cycles
-/19/15
Installation:make sure to provide suitable gasket lubrication with clean oil before screwing the cartridge on the valve body . Also make sure to screw the cartridge manually in to reach against the gaskets in the valve body. Material:internal components made out of high grade steel duly treated and fabricated. For more information please ask our technical office . Working temperature:min. -25°C (-13°F) max. 90°C (194°F) with standard BUNA N seals. min. -20°C (-4°F) max. 200°C (392°F) with optional VITON seals. Rating diagrams:all rating diagrams of this catalogue are measured with mineral oil of 46 cSt viscosity at 40° (104°F) temperature. All drawings dimensions are defined as mm in

DIRECT CONTROL PRESSURE ADJUSTMENT VALVES WITH RELIEVING
VRPRL/U..
Type
Operation Direct control pressure adjustment valve with relieving. Allows for free oil flow from E into U. When the pressure value set in U is Achieved, the valve will shut the pass between E and U in order to maintain constant pressure In U. Should the pressure in U further exceed the setting value, the pass in E will shut and the connection in U will joint to Dr to relieve eventual pressure peaks.

PRESSURE RELIEF VALVES WITHOUT RELIEVING, SPOOL TYPE
Type
RB..A
Operation Oil flow is permitted from 2 to 1 up to the pressure value set in 1. When this pressure value is reached, the spool throttles the passage between 2 and 1 to keep the pressure in 1 constant. The passage in 3 is used as a drain with steady connection to the discharge. There is no pressure relief from1 to 3, when pressure in the line 1 exceeds the set value.

Operation
The RM...W permits free oil flow from 2 to 1 while port 3 is always connected to tank. When pressure in 1 is the same as the valve set pressure, the spool restricts the passage between 2 and 1 so that pressure in 1 remains constant. Push-button operation allowed. (if used with energized magnet, the valve will change the actual pressure setting).

Type
RD..A
Operation Oil flow is permitted from 2 to 1 up to the pressure value set in 1. When this pressure value is reached, the spool throttles the passage between 2 and 1 to keep the pressure in 1 constant. The passage in 3 is used as a drain with steady connection to the discharge. There is pressure relief from 1 to 3, when pressure in the line 1 exceeds the set value.

Operation The RD..W permits free oil flow from 2 to 1 while port 3 is always connected to tank. when pressure in 1 is is the same as the valve set pressure, the spool restricts the passage between 2 and 1 so that pressure in 1 remains constant. When inlet pressure in 1 exceeds the setting of the valve, the pilot section 2 closes causing an imbalance across the main spool which then opens allowing relief flow to tank (3). Push-button operation allowed. (If used with energized magnet, the valve will change the actual pressure setting).

This valve permits free oil flow from 2 to 1 till pressure in 1 reaches the valve set pressure. Then the spool restricts the passage between 2 and 1 so that pressure in 1 remains constant while port 3 is always connected to tank. When the inlet pressure in 1 exceeds the setting of the valve, the valve act as a pressure limiter between port 1 and 3.

Operation The RP..X permits free oil flow from 2 to 1 while port 3 is always connected to tank. when pressure in 1 is same as the valve set pressure, the spool restricts the passage between 2 and 1 so that pressure in 1 remains constant. When inlet pressure in 1 exceeds the setting of the valve, the pilot section 2 closes causing an imbalance across the main spool which then opens allowing relief flow to tank (3).
