DATA SHEET Direct-acting 2/2 or 3/2-way pivoted armature valve • Direct-acting, media-separated valve up to DN 8 • Maintenance-free pivoted armature technology • Vibration-proof, block screwed coil system • Service-friendly, robust manual override • Explosion-proof variants Product variants described in the data sheet may differ from the product presentation and description. Type 1087 Timer, form A according to DIN EN 175301 - 803 Type 2518 Cable plug, form A according to DIN EN 175301 - 803 Type 2509 Cable plug, form A according to DIN EN 175301 - 803 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. Standard | EU | en | 2023 - 12 - 11 | 12 © Christian Bürkert GmbH & Co. KG, Subject to alterati
