The TRI-BLOCK series enables redundant shut-off in an armature housing. Two shut-off valves of the TRI-CON series, with the proven 3-fold eccentric, metallic sealing principle and an integrated intermediate relaxation (bleed port), make it possible to realize them in one valve.
This fitting makes it possible to replace the solution, which is commonly used in practice, with the use of two shut-off valves and one connector with only one. The fact that only one drive is needed is also of great importance.
