EXM1® Directional Proportional Valve: The solution to pollution issues and the dangers correlated to the use of hydraulic oil.
The new hydraulic and ecologic valve, called EXM1, has been developed and patented by Tech-Euroengineering. The EXM1 valve is a modern substitute of hydraulic valves by employing marine and fresh water as a working fluid, which is then released in the environment without contamination. It can be used in those areas likely to yield high risks of environmental pollution and that, potentially, could cause serious human injuries.
Where the idea comes from
The valve was born from a project that had the aim of creating a prototype of an entirely ecologic workboat by also eliminating the use of hydraulic oil in the movement systems of the crane to eradicate the risk of oil spillages in the environment.
The EXM1 valve is a hydrodynamic device 4/3-way linear suitable to the management and control of hydraulic double-acting actuators.
- The valve has been patented and tested to function using water as a working fluid. It can work either in an open and closed circuit.
- The system is able to directly draw non-demineralized water from the sea and to function in an accurate way for prolonged periods. without interruptions despite the impurities and corrosive power that characterize such a fluid.
Areas of application
The EMX1 valve is implemented in different sectors with advantages not only on an ecologic level, but also on a safety one. Furthermore, it can be used in retrofit projects of existent machineries.
Marine field
-Naval: the valve can be used, for example, on workboats, pipe-laying ships and fishing boats for several kind of purposes:
- Handling of lifting and movement systems.
- Actuators employed to move cranes and bulkheads.
- Actuators for movable bridges.
- Motion of pipes destined to on-board usage and to be laid.
-Oil and Gas: the valve can be used on off-shore platforms for different kind of activities:
- Hydraulic motion systems.
- Mobile lifting systems.
- Handling equipment systems.
- Control of machineries that work in a submarine field.
- Elimination of pollution risks thanks to the use of water instead of hydraulic oil.
- Complete removal of potential costs of Oil Spill Response due to oil leaks.
- Working fluid cost cutting.
- Reduced cost of maintenance.
- Energy savings related to the superior compressibility of the working fluid.
- Greater on-board cleanliness and safety for workers.
- Simplified usage through remote control.
Industrial field
-Steel industry: the valve can be used in a variety of hydraulic presses, such as:
- Hydraulic hot forging presses.
- Hydraulic hot shearing presses.
- Hydraulic hot moulding presses.
- Hydraulic hot extrusion presses.
- Hot billets shearing systems.
-Mining: the valve can be used for different purposes related to drilling machines:
- Handling of hydraulic systems.
- Motion control of hydraulic jacks.
The usage of the new hydraulic and ecologic EXM1 valve in the steel industry and mining field leads to many advantages such as:
- Increased plant safety due to the elimination of fire risks thanks to the use of water instead of hydraulic oil.
- Working fluid cost cutting.
- Optimized performance and speed due to the difference in fluids. compressibility.
- Reduction of the oil spillage pollution in the production area.
