•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. - 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 - 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
