Technical Information
ECO 80 Directional Control Valve
General information
General description
The ECO 80 LS is a hydraulic load sensing proportional valve group designed to give maximum flexibility
in design and build concept. The ECO 80 LS is designed as a load sensing directional control valve which
will lead to increased machine performance, higher efficiency, reduced cooling requirements and fuelsaving compared to conventional directional control valves.
ECO 80 LS features
PVG load-sensing proportional valves features and benefits summarized inb bullets below:• Load sensing directional control:‒ Proportional control of oil flow to a work function• Modular build concept:‒ Up to 12 basic modules per ECO 80 LS valve group‒ Different, interchangeable spool variants‒ System pressure up to 280 bar‒ Work port pressure up to 320 bar‒ Compact design and installation
ECO modules

EVP, pump side modules•••

Built-in pressure relief valve
Pressure gauge connection
Versions:‒ Open center version for systems with fixed displacement pumps‒ Closed center version for systems with variable displacement pumps‒ Integrated 25 bar pilot oil supply for hydraulic and electrohydraulic actuaqtion‒ Versions prepared for electrical LS unloading valve

EVB, basic modules•••

Interchangeable spools
Load holding check valve in channel P
Option for shock and suction valves for port A and B

Actuation modules
The basic module could be fitted with three main different actuation modules:• Mechanical• Electrical• Hydraulic• Pneumatic
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 eachapplication 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

W Warning
All makes/brands and types of directional control valves – inclusive proportional valves – can fail andcause 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, themanufacturer of the application is alone responsible for making the final selection of the products – andassuring 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).

EVOS - open spool through action
The EVOS open spool through action consists of an aluminum base with a rubber boot to protect thespool, mounted on the end of the valve slice, the connection with application is a female extension
assembled on the main spool.
The valve is actuated by directly pulling or pushing the main spool inside the valve hence controlling theflow. Actuating the spool fully will move all 5 mm and give full flow. The EVOS should be used with open
spool mechanical actuation and can be combined with any EVME, spring center, detent, through action
and micro switch.

ECO 80 Directional Control ValveEVP inlet module accessories
The generic EVP inlet module accessory platform includes the EVPX Electrical LS pressure unloading valve
and a plug for external pilot oil supply.
• EVPX Electrical LS Pressure Unloading Valve• PLug for external pilot oil supply
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 thesum of the tank and neutral by-pass pressure drop in an Open Center PVP configuration

•
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. Fulllever movement to one side will give full flow to the work ports. When the spool is moved 5mm it willstop 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 firstloosening the nut then adjusting the pin screw. After adjustment the nut must be tightened again
applying 8 ±1 [N•m] of torque.

Technical Information
ECO 80 Directional Control ValveECO 80 electrical - actuation
EVHC - electrical actuation
The EVHC consists of an aluminum base with two solenoids pressure reducing valves mounted on theend of the valve slice. When actuating with electrical proportional actuation, the main spool position isadjusted 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. Thisis done by means of two proportional pressure-reducing valves. The electrical actuator can be controlledeither 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 isnecessary 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 current response and hysteresis @ 25 bar Pp, 32 ctS, 55 °C. The ideal curve (red line) is determinedby 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 ValveECO 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 isnecessary 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.

ECO 80 Directional Control ValveECO 80 electrical - actuation
EVPN - pneumatic actuation
The EVPN is an aluminum plate with two threaded connections mounted on the end of the valve slice onside 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.
