PROLOAD LIVE LOADING SYSTEM
New generation dynamic or static capsulated disc spring system with defined compression length.
Typical problem
The stack of disc springs is too long for the of the available bolt length.
As a result usually the bolts need to be replaced which is time and cost consuming.
Solution
PROLOAD Live Loading Systems
- Improves reliability
- Compensates for pressure deviations and temperature fluctuations
- Reduces maintenance costs
- Lower friction ensures functionality
The full load and compensation length of the disc springs is available. With PROLOAD Live Loading Systems no torque measuring tools are needed!

PROLOAD-DYN LiveLoading
One of the main advantages of the PROLAOD-DYN LiveLoading system is that the disc springs slide on a smooth surface and cannot cannot catch on thread turns
The spring packs are protected in a housing against environmental influences and damage.
The spring stack is adjusted for optimal spring force and spring deflection by a spacer sleeve and a defined maintenance gap.
A torque wrench is not required for adjustment.
A reduction in compression due to packing consolidation or volume loss through abrasion is indicated by a larger maintenance gap. In this case, simply tighten the gland nut to restore the desired compression.

PROLOAD-STAT LiveLoading
Disc springs slide on an even machined surface rather on a bolt thread
Disc springs are encapsulated by outer cylinder against environmental impact
Disc springs never get over-compressed
No torque measuring tools necessary
Relaxation of the springset by volumeloss of the packing stack will show on an inspection gap.
Simply tighten the nut until the gap closes
PROLOAD-STAT Live Loading System acts as a prevention against mechanical destruction of packing
Extended nut screws on the existing valve bolt and eliminates the need for new longer bolts
