FEATURES
• Ruggedly built valve, particularly recommended for use with steam, superheated
water, corrosive fluids
• High-performance, maintenance-free stuffing box, resistant to thermal shock
• Mixer function (two pressure inlets at 1 or 3, one outlet at 2) or distributor function
(one pressure inlet at 2, two outlets at 1 and 3)
• Vacuum operation up to 10-2 mbar (PTFE and PEEK discs)
• Optical position indicator as standard
• Autoclavable valve for use at high ambient temperatures (up to 180°C)
