Handy to know.

  • Contact us for gearbox and actuation options.
  • Channel Guides & Slippers are manufactured from Gunmetal and help to reduce friction between the wedge and body during operation. Accurate alignment is aslo achieved. Channel Guides & Slippers are necessary when horizontal installation of valve is required. (On valves 350mm and above).
