Safety in systems
All makes and all types of control valves (incl. proportional valves) can fail, thus the necessary protection
against the serious consequences of function failure should always be built into the system. For each
application an assessment should be made for the consequences of pressure failure and uncontrolled or
blocked movements.

Technical Information
ECO 80 Directional Control Valve
General information
Warning
All makes/brands and types of directional control valves – inclusive proportional valves – can fail and
cause serious damage. It is therefore important to analyze all aspects of the application.
Because the proportional valves are used in many different operation conditions and applications, the
manufacturer of the application is alone responsible for making the final selection of the products – and
assuring that all performance, safety and warning requirements of the application are met.
The process of choosing the control system – and safety levels – is governed by the machine directives
EN 13849 (Safety related requirements for control systems).

EVPX electrical LS pressure unloading valve
The electrical LS pressure unloading valve is an accessory available for EVP inlet modules with EVPX
facility. The EVPX consist of a solenoid valve and a magnetic coil package, allowing the operator to relieve
the LS pressure to tank electrically.
Normally open (NO)
Relieving the LS pressure to tank results in a reduced system pressure level, which is determined by the
sum of the tank and neutral by-pass pressure drop in an Open Center PVP configuration

EVM mechanical actuation
•

•
EVH hydraulic actuation
•
EVHC electrical actuation
•
EVHCO On/Off Electrical actuation
EVM mechanical actuation
The EVM consists of an aluminum base with a lever mounted on the end of the valve slice on side B.
When actuating the lever the operator is directly pulling or pushing on the main spool inside the valve
hence controlling the flow. Actuating the lever fully will move the spool all 5 mm and give full flow. The
lever can be mounted / removed without having to remove the EVM base. The EVM should be used with
Electrical flow control spools and can be combined with any EVHC, EVH or Pneumatic actuator.
EVM without adjustment screws
The standard EVM without adjustment screws will allow a spool travel of 5 mm in either direction. Full
lever movement to one side will give full flow to the work ports. When the spool is moved 5mm it will
stop due to a mechanical limitation build into the EVM base.
EVM with adjustment screws
The spool travel in either direction can be limited by the adjustment screws. This will limit the flow out of
the work ports thereby reducing the speed of an application. The spool travel is adjusted by first
loosening the nut then adjusting the pin screw. After adjustment the nut must be tightened again
applying 8 ±1 [N•m] of torque.

ECO 80 Directional Control Valve
ECO 80 electrical - actuation
EVHC - electrical actuation
The EVHC consists of an aluminum base with two solenoids pressure reducing valves mounted on the
end of the valve slice. When actuating with electrical proportional actuation, the main spool position is
adjusted so that its position corresponds to an electrical control signal.
The control signal is converted into a hydraulic pressure signal that moves the main spool in the EVB. This
is done by means of two proportional pressure-reducing valves. The electrical actuator can be controlled
either by a current amplifier card, or directly from a programmable microcontroller.
The actuator controls the spool by building up pilot oil pressure on the end of the spool. For the EVHC is
necessary a pilot oil pressure between 25 and 30 bar.
The EVHC should be used with Electrical FLOW CONTROL spools and can be combined with any EVM.
EVHC Dimensions
Schematic
Schematic is not available.
EVHC spool stroke vs current characteristics
EVHC current response and hysteresis @ 25 bar Pp, 32 ctS, 55 °C. The ideal curve (red line) is determined
by the main spool neutral spring. The EVHC hysteresis is around ±7.5% (grey region).
The hysteresis is affected by viscosity, friction, flow forces, dither frequency and modulation frequency.
The spool position will shift when conditions are changed e.g. temperature change.

Technical Information
ECO 80 Directional Control Valve
ECO 80 electrical - actuation
EVHCO - Low current on/off electrical actuation
The EVHCO consists of an aluminum base with two solenoids valves mounted on the end of the valve
slice. When active with electrical signal the main spool goes straight to end of stroke, A or B side.
The electrical signal is converted into a hydraulic pressure signal that moves the main spool in the EVB.
This is done by means of two on/off solenoid valves.
The actuator controls the spool by building up pilot oil pressure on the end of the spool. For the EVHCO is
necessary a pilot oil pressure between 10 and 28 bar. The EVHCO should be used with Electrical flow
control soft spring spools and can be combined with any EVM.

EVPN - pneumatic actuation
The EVPN is an aluminum plate with two threaded connections mounted on the end of the valve slice on
side A. When applying pressure through one of the ports, one side of the spool is pushed to one direction
hence flow is coming from the work ports. The EVPN is to be combined with an EVM and a special EVBS
spool for EVPN.
EVPN Dimensions
The two plugs in the bottom of the EVPN actuator is for option mount for upside down pneumatic ports.
