MATERIALS IN CONTACT WITH FLUID
• High fl ow due to angled seat design
• Anti-waterhammer design (fl uid entry under the disc)
• Vacuum operation up to 10-2 mbar
• Wide range of piston-type operators (32 - 50- 63 - 90 -125 mm dia.) rotatable
through 360°, for maximum performance at different minimum pilot pressures
• High performance, maintenance-free stuffi ng box
• The valves satisfy Pressure Equipment Directive 97/23/EC, category 1 (DN > 25)
or article 3.3 (DN ≤ 25)
