1.

 

General

 

•

 

Before beginning, it is strongly recommended to review both the disassembly and assembly chapters. 

•

 

Both the disassembly and assembly chapters are for bare stem valves. 

•

 

General cryogenic service does not allow any lubrication for internal and soft parts such as seals and seats. 

•

 

For bolts, studs, nuts and stem seals use Gleitmo 599 grease only. 

•

 

An equivalent grease may be applied, when approved by Habonim engineering 

•

 

For any discrepancies please contact Habonim

Disassembly

 

The following instructions are for in-line disassembly of valves of all sizes

. 

 

 

IMPORTANT: No need to disassemble the valve from the pipeline, the valve is 
designed to be maintained in-line. 

 

 

2.1.

 

Refer to the exploded views on page 20 to identify the valve parts and their order. 

2.2.

 

Cycle the valve with the line pressure fully relieved before attempting disassembly to ensure 
pressure has also been discharged from the valve cavity. 

2.3.

 

Cycle the valve to the open position.  

2.4.

 

For manually operated valves ensure that the handle is positioned parallel to/in line with the 
pipeline; for automated valves check that the stem flats or the stem groove are parallel to the 
pipeline. 
 
 

WARNING: Disassembling or assembling the valve with the ball in the closed position 
may cause damage to parts. 

 
 

2.5.

 

Remove all bonnet bolts. 

2.6.

 

Remove the bonnet. 

2.7.

 

Fully disassemble the bonnet. 
 

 

WARNING: Be careful not to damage the sealing surfaces.

 

 

2.8.

 

Remove the stem nut, locking clip (or tab lock washer), the two disc springs, follower, slide bearing, 
anti-abrasion ring and the stem seal. Remove the stem, the stem bearing and the stem thrust seal. 
Place all removed components in a clean secure area. 

2.9.

 

Discard all repair kit parts: the stem thrust seal, anti-abrasion ring, stem seal, stem bearing and the 
slide bearing. Take care not to scratch or nick the stem bore area of the bonnet. Clean the stem and 
the stem bore area.
