Special construction:
The surface finish of internal parts and self-lubricating bearings maximize input energy transfer directly to the valve stem.
Even greater efficiency is achieved through the tension loaded on the spring, thereby minimizing radial loads on the stem.
To ensure safety during installation and maintenance, the spring module has been designed so that it can only be removed when the spring is in the fully extended position.
