The micro valve type 7024 from Schubert & Salzer Control Systems is now also available with a socket-weld connection. This is intended to facilitate leak-free installation in high-pressure applications.
The needle valve itself has been available since 2024. It is designed for applications where very small flow rates (Kv values from 0.0027 to 1.7) and high pressures (nominal pressure PN320) need to be controlled or shut off.
The valve features a housing made of solid stainless steel and hardened valve spindles. The seat assembly, i.e. the sealing part between spindle and housing, is made of hardened stainless steel or hard metal, provides metallic sealing, and is replaceable. The high-pressure packing is designed to ensure tightness even after frequent switching – including for tiny molecules such as hydrogen.
Optional, but essential for unlocking the valve’s full potential, is the integrable positioner type 8049. Various versions are available, including protected designs (Ex, FM) as well as interfaces via IO-Link or to the Industrial Internet of Things (IIoT).
Via IO-Link, the positioner transmits the information required for predictive maintenance through a single cable. If the positioner needs to be replaced, this can be done easily thanks to the top-mounted installation, according to the manufacturer. The new positioner then configures itself via IO-Link using the data from its predecessor.
A dedicated module is available for IIoT connectivity.
