How to match a Nieruf coaxial valve to our alternative
- Function: 2/2 or 3/2; NC or NO
- Size/connection: DN and thread (e.g., DN15, 1/2" BSP)
- Voltage & duty: 24 VDC vs 230 VAC; duty/ambient
- Media & seals: water, air, gas, viscous fluids; seal material
- Pressure & temperature: operating range, any counter-pressure
FAQs
Are these direct replacements for Nieruf CV01/CV02/CV03?
Yes. We supply like-for-like builds (2/2 or 3/2; NC/NO; brass or stainless; 24 VDC/230 VAC). We’ll verify pressure, media and duty before quoting.
Do you offer NO and NC versions?
Both. Tell us your fail-safe state and we’ll specify NO or NC to suit the application.
What about lead times?
Many popular configurations are stocked for rapid dispatch. If a custom build is needed, we’ll confirm a firm lead time before you order.
Can you help with viscous media or counter-pressure?
Yes. Coaxial valves are well-suited to these conditions. Share viscosity, pressure, temperature and cycle rate; we’ll recommend the best seat/seal combination.
Do you provide documentation?
Yes — drawings, datasheets, Certificates of Conformity, and other documentation aligned to our ISO 9001/14001 systems.
