Main body elements made of ductile iron GGG40
PN25/PN40 raised face flanged ends to DIN 2501 (BS EN 1092-1)
Top mounted aluminium I/P positioned electro-pneumatic actuator (fail closed) and digital I/P positioner
Built-in cyclone separator and free float steam trap provide dry, high-quality steam and eliminate water hammer
Combined stainless steel screen for trap and separator reduces cost and piping space
Zero/span adjustment can be performed by auto-tuning via the positioner menu
Self-adjusting chevron packing minimises seal leaks, stem wear and stiction/hysteresis problems
