1. Fully sealed: General, Durable, Safe
   •Laminated stack made of stainless steel and graphite lends additional elasticity to the sealing ring.
   •Triple offset design guatantees a frictionless swivel movement of the sealing ring into the seat.
   •The ZETRIX seals according to the area seating principle; the required contact pressure is applied via the actuator.
   •Maximum closing force with minimum effort because of optimised contact angles.
2. Modern development methods, tested in our own experimental lab
   •Finite element method
   •State-of-the-art flow simulations
   •Rigorous tests(here: firesafe)
   •Characteristic measurements
   •Contact angle calculation
3. High-precision manufacturing
   •The valve bodies are manufactured on fully automatic, CNC controlled machining cetres.
   •Fully automatic welding robot with an integrated measuring system.
   •The three-dimensional measuring system allows the compatison with 3D data.
   •Computer aided leak according to DIN EN 12266
