GENERAL FEATURES: Body valve material: A351-CF3M (316L S.S.). Valve ends: see code plan. Assembling is possible in all positions: upright, flat or angled. Range available from DN 15 to DN 50 in the Double Acting versions, Spring Return N.C. from above and below the plug, Spring Return N.O. from below the plug. The performance and the pressure’s diagrams are the same as per Standard versions but limited at PN16 On request: versions for vacuum and oxygen service 2014/34/EU ATEX configuration to request at time of order.
CONTROL MEDIA: Driving media: compressed air, lubricated or dry, gas or neutral media. Ambient temperature: -10°C to +60°C
OPERATING MEDIA: Air, water, alcohol, oil, petroleum products, saline solutions, steam, etc. (as long as compatible with CF3M (316L S.S.) or PTFE). Pressure from 0 to 16 bar (steam from 180°C, from 0 to 10 bar) depending on the size and model chosen see following pages. Temperature from –10°C to 180°C. Max. viscosity 600 cst (mm2/s).
ISO 2852 version on request
Working pressure up to 16 bar (for details see diagrams).
