The 0121 valve is a direct-acting, media separated pivoted armature valve. It is
available as a 2/2 and 3/2-way variant. As a 3/2-way variant, it can be used as a
distributor or mixing valve. Various diaphragm materials and circuit functions are
available depending on the actual application. The range of bodies includes stainless
steel, PTFE and PVC versions. The solenoid coils are moulded with a chemically
resistant epoxy. Since the coil system is separated from the medium by a
diaphragm, the valve is especially suitable for critical media such as aggressive
acids and lyes. The 0121 is equipped with manual override for start-up and testing.
To reduce energy demands, all the coils can be delivered with electronic power
reduction or as an impulse variant. The switching status can be indicated via position
feedback as a binary or NAMUR signal.
