ASCO
ASCO - Electrical controlled NAMUR valve
Valve according to NAMUR standard for mounting on, among other things, pneumatic rotary attachments. The same valve has 3/2 or 5/2 function depending on which of the two provided intermediate plates is used.
There are many different versions of series 551. It can be provided with most voltage variants, with ATEX approved coil for explosive environments and with a low power pilot valve. In addition to aluminium, housing is available in SS316 steel or brass for low temperatures, - 40 °C. All electrically and air operated valves with aluminium housing have environmental protection as standard. This means that all the internal parts are totally sealed against fluids, dust, corrosive substances etc. that may be present in the direct surroundings.
Even the exhaust from the return chamber is led to the exhaust ports via an internal channel. For further protection, the pilot exhaust can also be led away to prevent contamination entering in this way. The environmental protection makes the 551 series suitable for both dirty environments and clean rooms. The electrical enclosure protection for all models is IP65.
