Possibility of vertical and horizontal assembly,
see data sheet HA 4057
Distributors of the RPEK1-03 type are the basic elements
for building blocks through horizontal and vertical
assembly. This catalogue describes the preparation of
the main unit, made up of two to eight distributors, by
horizontal assembly. The distributors controlling the
direction of the working fluid’s flow to the individual
appliances share common channels P and T. During the
circuit design it is always necessary to check if the flow
through the common channels covers the consumption
of all appliances in all phases of the hydraulic equipment
working cycle. Channels A, B outputs at the upper
surface of the body are provided with threads G1/4 (type
G), or SAE 9/16-18 (type S), or are prepared for vertical
assembly (type O) – i.e. brought out onto a ground
surface. Channels P, T, A, B outlets on the side surfaces
of the body are prepared for horizontal assembly – i.e.
brought out onto a ground surfaces or provided with a
sealing ring recess.
The individual distributor bodies are connected into a
compact block using three bolts. Fastening angles serve
to mount the block to the base with four screws.
An assembled block feed is provided by a plate with
connecting threads G3/8 in channels P, T. It is also
possible to use plate with a built-in pressure relief valve
to regulate the maximum pressure in the circuit.
Use data sheet No. HA 5027 to create more complex
assemblies with the use of the horizontal and vertical
assembly, while also using additional building elements.
The RPEK1-03 directional control valves consist of cast
iron housing (1), control spool (5) with two centering
springs (4) and operating solenoids (2, 3).
The three-position directional valves are fitted with two
solenoids, two-position directional valves have either
one solenoid.
*The operating solenoids are DC solenoids supplied
through connectors A, B (6, 7). For AC supply the
solenoids are provided with rectifiers, which are
integrated directly into the connectors A, B (6, 7). Tthe
connectors can be turned by 90° around . By loosening
the nut (8), the solenoid can be turned around its axis up
to 360°.
In the case of solenoid malfunction or power failure, the
spool of the valve can be repositioned by manual
override (9), provided the pressure in the T-port does not
exceed 25 bar.The standard design of the emergency
control may be additionally fitted with a pushbutton with
a rubber cover.
The basic surface treatment of the valve housing (1) is
phosphate coated and the solenoids (2, 3) are zinc
coated.
*Magnet coils are not included in the valve supply. The
coil types selected by the customer must be ordered
separately.
