Assembly Instructions AKH2A
The general installation and maintenance instructions must be observed.
1. Screw stud bolts (120) into body (010).
2. Insert stem (040) from inside of body in such a way that the at side is parallel to
body longitudinal axis.
3. Insert chevron packing (100).
4. Install gland insert (065), gland follower (060), safety washers (150), hexagon nuts
(110) and grounding strap (170) also on valves with actuator.
5. Install hand lever (070) on to stem (040) and tighten it using lock washer (130) and
hexagon bolt (140).
6. Insert rst ball seat ring (030) into body (010).
7. Insert ball (050) to valve stem by pushing the ball in a downward motion through
valve body.
8. Turn hand lever 90° of longitudinal axis of body.
9. Install second ball seat ring (030) on to ball (050).
10. Install side piece (020) on to body (010).
11. Install body bolts (080) and hexagon nuts (090) and tighten by crisscross method to
recommended torques.
12. Assemble stop (210) with hexagon bolt (220).

Disassembly Instructions for AKH2A
For all jobs which are to be carried out on an installed valve, the works safety requirements and the general accident prevention instructions must be observed. Moreover,
the general installation and maintenance instructions for atomac uorcarbon resin lined
valves must be considered.
1. Prior to disassembly, the valve must be cleared of all uid according to the above-
mentioned instructions. Particular care must be taken that during rinsing and draining of the piping, the valve is opened and closed repeatedly. These cycles (opening
and closing) are to be repeated during draining of the piping. Only when following
this procedure, is it ensured that all remaining pressure inside the body (stem guide
and ball seats) is eliminated.
2. For disassembly of the valve, put body on a work bench with a soft cover (rubber
mat). Remove hexagon bolt (110) and serrated lock washer (150).
3. Open valve completely. Remove hand lever (070).
4. Disassemble grounding device (170).
5. Disassemble gland follower (060) and gland insert (065). If necessary, stud bolts
(120) can also be removed now.
6. Remove body bolts (080) and separate side piece from body.
7. Remove rst ball seat ring (030).
8. Put ball in closed position and push ball out of the body.
9. Remove stem (040) by pushing it down through
the body (010). Care must be taken not to
damage body liner.
10. Chevron packing (100) can easily be removed.
11. If necessary, remove hand lever stop
(210) by releasing bolt (220).

Manual Actuator
(worm gear)
The fully closed, waterproof actuator consists of a body with lid, worm gear, input
shaft and hand wheel. For the correct adjustment of the ball position, there are two
adjustable stops mounted in the body.
The gear is fully greased and does not need any further lubrication.
The actuator with hand wheel is mounted on a bracket with four stainless steel bolts.
The on/off position is indicated through a pointer. The actuator is self-locked.

Special Recleaning and Packing Procedures
1. R e c l e a n i n g
The ball valve should be thouroughly cleaned with a clean, dry, lint-free towel and
blown off with dry nitrogen gas. This will assure that the valve is free from moisture,
grease and other media before packing.
2. P a c k i n g
Prior to packing, the ball valve should be jig welded in a PE-foil (0,2 mm thick). The
bag contains desiccants acc. to DIN 55473, quantity acc. to DIN 555474 and a
moisture indicator.
