FEATURES:
• Ruggedly built valve, particularly recommended for use with steam, superheated
water, corrosive fluids
• High-performance, maintenance-free stuffi ng box, resistant to thermal shock
• Pressure can be applied to any port as needed by the process
• Anti-waterhammer design (fl uid entry at orifi ce 1), recommended for use with liquids
• Vacuum operation up to 10-2 mbar • Allowable backpressure: up to 40 bar
• Optical position indicator as standard
• Autoclavable valve for use at high ambient temperatures (up to 180°C)
• The valves satisfy Pressure Equipment Directive 97/23/EC, category 1 (DN > 32) or article 3.3 (DN ≤ 32)
