Design Benefits:
1.No torsion of bellows. Non-rotating stem prevents torsion of bellows and ensures long cycle life on all valves.
2.Long cycle life bellows Designed for and successfully tested in high pressure/temperature applications.
3.Low torque due to non-rotating stem, central grease fitting for lubrication of stem nut and for high pressure valves, stem thrust bearing.
4.Hermetically sealed. Body bonnet welds provide a hermetically-enclosed vessel in most designs.
5.In-line servicing. Stem-bellows assembly can easily be removed and replaced on valves with bolts bonnet. On seal-welded valves, removal and replacement of weld is necessary. Special power tools are available for cutting seal weld.
