GENERAL FEATURES
Threaded valve ends, as per ISO 228/1 and ISO 7/1 – 其他 types available on request.
Assembling is possible in all positions: upright, flat or angled.
Range available from 3/8” to 2” in the Double Acting versions, Spring Return N.C. from above and below the plug, Spring Return N.O. from below the plug.
According to 97/23 EC “PED”
ATEX version in conformity with directive 94/9/EC (to request at time of order)
The variations in the actioning of the valve, the several combinations and the possibility to intercept the fluid from above or below the plug, originate multiple versions of the automatic valve.
In the table below are indicated the standard versions with the main parameters.
On the basis of the kind of valve and the variations of pressure ?P that must be intercepted, the necessary control pressure can be individuated, and consequently, the code for the corresponding valve.
