To achieve flameproof protection, the new coils replace the more usual metal housing with a novel plastic design.
This housing features an extremely small internal space to ensure that any spark does not have enough oxygen to ignite and cause an explosion - and integrates an interchangeable safety fuse.
This approach saves an enormous amount of space and weight.
The new explosion-proof coils meet ATEX standards, providing EExdmIIC T4, T5 and T6 or EExiaIIC T6 level protection.
Parker Lucifer can equip a large proportion of its solenoid valve designs with the new electrical parts, in particular the low power (2.5 W) and intrinsic safety types.
PNEUMATIC CONTROL USING FIELDBUS-COMPATIBLE VALVE ISLAND.
At Achema 2006, Parker Lucifer will highlight its unique EExPress fieldbus-compatible manifold which allows pneumatic actuation systems to be sited in hazardous (Zone 1 and 2) processing environments without the need for expensive explosion-proof pressurised cabinets.
The EExPress Bus Manifold is a stackable valve island system that fully integrates 5/2 solenoid valves, control electronics and input sensors for Zone 1 and 2 environments.
It is compatible with the Profibus DP fieldbus - the protocol preferred by most process industries.
One Profibus address can operate up to 32 individual 5/2 modular solenoid valves, or a combination of valves and actuator position sensors.
The valve island's fieldbus compatibility also supports advanced remote diagnostics down to individual valve and sensor level - further supporting the demanding needs of the continuous processing sector.
The fieldbus connection to the terminal can be made by either optical fibre or copper - with the aid of intrinsically safe circuits.
EExPress is fully certified to ATEX and LCIE standards, is CE marked and EMC tested and approved.
