Sliding gate valves

We offer solutions for the full range of control applications, from advanced control systems to simpler installations with ball valves or butterfly valves. In the process industry, many have already discovered the advantages of the AL 72 series of sliding gate valves from the German manufacturer Schubert & Salzer. This is a well-proven technology that has long demonstrated reliability and high control accuracy.

Advantages of Sliding gate valves

• Compact and lightweight design
• Easy installation and maintenance
• Handles high differential pressures (up to 100 bar)
• Flexible Kv values with easily replaceable control disc
• Low wear, as any cavitation occurs 1–2 meters downstream of the valve, in the center of the pipe
• Ideal for steam applications
• Temperature range: -60°C to +530°C

The images illustrate the valve’s easily replaceable control disc, as well as a size comparison between the compact sliding gate valve and a globe valve for the same application.

When applications place even higher demands, for example when handling abrasive liquids, particles, or fiber suspensions, we recommend our robust AL 74 ball sector valves, designed for long service life and manufactured with a focus on the highest quality.
