Product Overview
The SCHUBERT & SALZER 8231/050VKN01-5M—1-Z-1 (Part No. 4065270) is a pneumatically actuated angle seat valve engineered for precise shut-off and control of neutral and aggressive media in industrial process systems. Manufactured by Schubert & Salzer, a recognized specialist in process and control valve technology, this valve utilizes a robust piston actuator acting on an inclined valve stem, delivering high flow capacity with minimal pressure loss compared to conventional globe or ball valve designs. The 8231 series is designed for reliable on/off service and is widely deployed as a final control element in fluid handling, steam, and pneumatic process lines where tight shut-off and long service life are essential.

Engineering Features & Advantages
- Precision Performance: The inclined seat and stem geometry provide a streamlined flow path with significantly reduced pressure drop and higher flow coefficients (Kv) compared to straight-through globe valves, ensuring efficient media transfer.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a durable piston actuator and robust body construction suitable for demanding process cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing piping or control interfaces.
- Fast Actuation Response: Pneumatic piston design delivers rapid opening and closing strokes, supporting high-cycle on/off control in automated process lines.
- Versatile Media Compatibility: Suitable for neutral, slightly aggressive, and gaseous media when specified with appropriate body and seal materials.
Typical Industrial Applications
This angle seat valve is commonly deployed in steam injection and sterilization lines, chemical dosing and transfer systems, water treatment and filtration plants, and general pneumatic process control circuits. It is also well suited for food and beverage processing, pharmaceutical utility skids, and industrial heating/cooling loops where reliable media shut-off and high flow capacity are required.
