Technical Information
ECO 80 Directional Control Valve
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 fuel saving 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
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
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
W 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).

Technical Information
ECO 80 Directional Control Valve
The ECO 80 EVB basic modules, also referred to as work sections, are the interface between the ECO 80 directional control valve and the work function such as a cylinder or a motor. The EVB comes in two main variants – a low body and a medium body with shock/anti-cavitation valve facility (PVLP)

Technical Information
ECO 80 Directional Control Valve
EVB basic modules - mechanical acting
The EVB low body is intended for controlling a work function where the function behavior in terms of flow and pressures allows dependency on the load pressure of other functions used simultaneously. The integrated load drop check valve prevents flow back from work ports influencing other functions.
The EVB low body features:
•Integrated LS shuttle network
•Load drop check valve

The EVB low body is intended for controlling a work function where the function behavior in terms of flow and pressures allows dependency on the load pressure of other functions used simultaneously. The integrated load drop check valve prevents flow back from work ports influencing other functions. Compared to the EVB low body the medium body has the option of adding PVLP/PVLA to the work section.
The EVB medium body features:
•Integrated LS shuttle network
•Load drop check valve
•Shock/anti-cavitation valve and suction facility (PVLP/PVLA)

The PVLP will relief a pressure peak to the internal tank galleries and will furthermore suck oil from the tank to the work port to prevent cavitation. Pressure settings range 32-320 bar [460-4641 psi].
Features:
•Shock valve
•Anti-cavitation
•Lifetime of 200,000 actuations
•Optional fixed or adjustable

The PVLA will suck oil from the tank to the work port to prevent cavitation by the 0.5 bar spring. The plug will ensure that when using a single acting spool, all flow returning through the work port is led to tank.

Technical Information
ECO 80 Directional Control Valve
The mechanical acting EVBS spools determine the flow out of the work section and are based on a generic platform with a wide selection of additional features, enabling you to tailor the EVBS to suit the demands of any hydraulic system and any function.
The mechanical acting EVBS spool comes in four different main variants:
•EVBS Female Extension
•EVBS Female Extension and through acting
•EVBS Female Extension and Detent 03 position and 02 position spool out or in1
•EVBS Female Extension and Micro Switch
1For 02 position detent spool out is necessary to use an accessory part number 11173406, see EVME, detent 02 position spool to A or B
