Sambo Temp Comp Spring-loaded Stem Nut

Sambo Temperature Compensating Spring-loaded Stem Nuts can be operated independently or engaged with a bevel gear and super gear box.

• Temp comp spring-loaded stem nut can allow for some displacement in axial direction through the gear box stem nut. Thus, it can prevent damages to valve and gear box caused by excessive high load from outside.
• Stem nut can be separately attached to bevel gear and super gear box to play the role of buffer.
• The pressure inside temp comp spring-loaded stem nut is pre-set higher than the valve thrust and it can prevent any movements at normal times.
• When thrust increases with the valve stem’s thermal expansion, TCS device starts the absorption and compensation of the thrust.
