Root Valves

• Hard Seat - Tungsten Carbide or Ceramic Ball provides a seating surface that prevents cutting a leak path into the seat due to repetitive use
• Straight Thru Bore - 1/4" orifice straight thru bore give higher C_v than angle pattern. Straight thru pattern makes the valve inherently roddable.
• Viton o-ring stem seal for high temperature-corrosive service
• Dust Cover - Keeps dirt, rain, etc from entering the bonnet stem assembly and prevents lubricant washout
• O-ring packing is below the threads to prevent process from reaching the threads and causing galling and corrosion
• Back Seating of the Stem - Prevents the stem from accidentally being backout and seats metal to metal in the full open position
• Stem is Nickel Plated - Prevent galling prevalent in similar metals
• Mirror Bonnet Finish - Bonnet bore is polished to 16 RMS. This greatly extends to life of the Viton oring.
