Glossary of technical terms used
› A hydraulic mechanism is one in which energy is transmitted via the compressive energy of the working fluid.
› A hydraulic directional control valve is a valve designed to control the direction of movement or stop the output component of an appliance.
› The volumetric flow rate Q is the amount of liquid in volume units that flows through a given flow cross-section per unit time (SI unit is
m
3
s
-1
, in practice the unit l/min is used)
› The control solenoid is designed to reposition the valve spool that interconnects or closes the ports in the body. The solenoid consists of
an excitation coil which, by passing an electric current through the winding, generates a magnetic field which exerts a force on the armature of
the mechanical control system.
› Pressure is the force acting per area unit (SI unit Pascal (1 Pa = Nm -2 ), in practice the unit used is bar (1bar = 0,1MPa)
1. Use of product
The RPEX3-06 hydraulic valve is a directly controlled, solenoid operated spool valve. The valve body has a connection pattern at the base with a
nominal clearance of DN 06 according to ISO 4401. The product is designed to control the movement direction of the hydraulic cylinder piston rod
or the rotation direction of the hydraulic motor output shaft by connecting the individual channels via a spool in the valve body. By stemming the
fluid flow through the valve spool, the movement of the appliance can be stopped.
Valves with ATEX certification according to Directive 2014/34/EU and IECEx certification according to IECEx OD 009 and related harmonized
standards may be used in explosive atmospheres consisting of mine gas, gas or dust. The valves are marked with the CE Ex mark of conformity and
are accompanied by a Declaration of Conformity.
Use in explosive atmospheres:
Class I
, mines, where the explosive atmosphere of mine gas is prodominantly methane
The valve has a high degree of protection (EPL = Mb), which makes iniation unlikely during the interval between gas discharge and valve shutdown.
It is designed for category M2 devices that remain off after gas discharge.
Class II , where the explosive atmospere consists of gasses other than mine gas
The valve has a high degree of protection (EPL = Gb) which allows the valve to be used in zones 1 and 2. There is a risk of explosion.
The valve is certified for all gas groups - IIA (typical is methane), IIB (typical is ethylene) and IIC (typical is hydrogen).
Class III , where the explosive atmosphere consists of dust and combustible flammable particles
The valve has a high degree of protection (EPL = Db) which allows the valve to be used in zone 20. There is a risk of explosion.
The valve is certified for all dust groups - IIIA (combustible flying particles), IIIB (non-conductive dust) and IIC (conductive dust).
CLASS I – MINES CLASS II (IIG) - GAS CLASS III (IID) - DUST

Area of application:
DANGER
Signal word combined with a warning sign used to signify that a dangerous situation which could result in
death or serious injury is imminent.
WARNING
Signal word combined with a warning sign used to signify a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
CAUTION
Signal word combined with a warning sign used to signify the occurrence of a potentially dangerous situation
that could result in death or serious injury if not avoided.
