General Information
CHECK VALVES and PILOT CHECK VALVES
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 specications of different items. For further safety of your hydraulic equipment and of
all valves assembled on it, we either recommend use suction lters (rather than return lters) or separated
lter lines.
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 ofce .
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 dened as

Operation
This valve is specially recommended for use as safety device for actuators, when
tubing break is suspected. Free oil ow is allowed from D to C while a limited oil
ow up to the required capacity only is allowed in the opposite direction. If a tubing
break happens, the outlet ow from the actuator exceeds the original setting value
while stopping the whole circuit and thus preventing further function of the actuator.
The valve must be set directly on the application. Use of a pressure adjuster on the
downstream side of the valve and the relevant tubing section is recommended. The
space S must provide for an oil ow which is 50% bigger than the maximum stan-
dard capacity.

Operation
The valve allows oil ow from D to U and stops it in the opposite way (from U to
D). Free oil ow from U to D is strictly possible when the pilot pressure in P is strong
enough to open the valve poppet. To assert the minimum opening pressure divide the
value of pressure in U by the pilot ratio. To provide best valve performance from U to
D make sure that no counterpressure arises in D.

Operation
The oil ow is permitted from 2 to 3 and stopped in the opposite direction. A free oil
ow from 3 to 2 is strictly possible when the pilot pressure in 1 is enough to release
the valve poppet. The minimum release pressure can be gured by dividing pressure
value in 3 by the pilot ratio. To assure best valve performance from 3 to 2, make sure
that no counter pressure arises in 2.

from U to D is strictly possible when the pilot pressure in P is strong enough to open

Operation
Allows oil ow from D1 to U1 and stops it in the opposite way (from U1 to D1). Free
oil ow from U1 to D1 is strictly possible when the pilot pressure in U2 and D2 is strong
enough to open the valve poppet. To assert the minimum opening pressure divide the
value of pressure in U1 by the pilot ratio. To provide best valve performance from U1 to
D1 make sure that no counterpressure arises in D1. A built-in shut-off valve allows for
ow break from D1 to U1 and viceversa, so that - at wish - the operator may cut the
check valve off the hydraulic system.

Operation
Multiple coil versions are available to allow use with direct and alternated current.
Thermal insulation class: F (Tmax = 155°C) – (VDE 0580)
Relative duty cycle: ED 100% (VDE 0580)
To assure ED = 100% and perform continuous coil operation, the following conditions should be met:
TA +∆T < Tmax
Whereas:
-TA = ambient temperature
-∆T = temperature increase due to operation
-Tmax = maximum admissible temperature according to insulation class
We therefore recommend always checking that the maximum ambient temperature is same as Tmax - ∆T
(providing no special operating requirement are there).
Safety standards (DIN 40050):IP54 without connector

Operation
Proportional coil. 12 and 24 coils direct voltage, supply a force proportional to the current amount.
thermal insulation class: F (TMAX = 155 °C) - (VDE 0580).
Relative duty cycle: ED = 100 % (VDE 0580).
To assure ED=100% and perform continuous coil operation, the following conditions should be met:
TA +∆T < TMAX
TA= ambient temperature; ∆T = a temperature increase due to operation; TMAX = maximum admissible temperature
according to insulation class.
We therefore recommend always checking that the maximum ambient temperature is same as Tmax-∆T (providing no
special operating requirement are there).

”CC-CA”, “CL” and “CP” CONNECTORS
Operation
There are 3 types of different solenoid connectors:
“CC-CA” 2-poles + GROUND electric connectors in compliance with DIN and A/ISO standards 43650 and 4400.
Electric connectors suitable for connection of DC and AC current coils. Type of current must be same as for the coil
used.
“CL” 2-poles + rectier + GROUND electric connectors in compliance with DIN and A/ISO standards 43650 and
4400.
Electric connectors suitable for connection of DC current coils BE…RAC. AC current operation only. Use of these po-
les depends on the type of valve used.
“CP” 2-poles + rectier + GROUND electric connectors in compliance with DIN and A/ISO standards 43650 and
4400.
Electric connectors suitable for connection of DC current coils BT…RAC. AC current operation only. Use of these po-
les depends on the type of valve used.
