BR21a Samson Pfeiffer PTFE-Lined Drain Ball Valve

Built with precision sealing and high chemical compatibility, the BR21a is perfect for applications requiring clean discharge, sampling, or system emptying. The valve’s full-bore design supports unrestricted flow, while the PTFE lining minimizes the risk of media buildup and ensures reliable, contamination-free operation. Compatible with manual or automated actuation, the BR21a supports flexible integration into process control systems where safety, hygiene, and corrosion resistance are paramount.

Key Features

Key features and benefits of BR21a Samson Pfeiffer PTFE-Lined Drain Ball Valves.
1

Key Features

The BR21a is fully lined with PTFE, offering excellent resistance to a wide range of corrosive and aggressive chemicals. This ensures long-term durability and process reliability in even the harshest environments.
2

Key Features

Engineered to be installed at the lowest point of a vessel or pipeline, the BR21a enables complete and controlled drainage. This minimizes media residue, supports clean-in-place (CIP) processes, and prevents cross-contamination.
3

Key Features

Its compact design makes the valve ideal for tight installation spaces, while still allowing for manual or automated operation. This gives process engineers flexibility when designing efficient and space-conscious systems.
