Features

  • Fixed, integral wedge nut prevents vibration and ensures durability
  • Stem seal replaceable under pressure
  • The ductile iron core is fully vulcanized with drinking water approved EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber
  • The wedge has a large through bore and as there are no hollows in the core, stagnant water or impurities cannot collect and cause contamination
  • Stainless steel stem with rolled threads for high strength
  • Full circle brass thrust collar provides fixation of the stem and low free running torques
  • Double stem seal: a replaceable polyamide bearing with two O-rings and an O-ring on the stem
  • Round bonnet gasket fixed in a recess groove in bonnet preventing it from being blown out by pressure surges
  • Bonnet bolts encircled by the bonnet gasket to protect against contact with the fluid and against corrosion
  • Fusion bonded epoxy coating acc. to GSK, blue RAL 5017
  • Bonnet and gland bolts sealed with hot-melt for protection against corrosion
  • Maximum operating torque acc. to BS 5163 type A for economical actuator size
