The BR22a Samson Pfeiffer Bottom Drain Ball Valve is specifically designed for the efficient and complete drainage of process vessels, pipelines, and reactors—ideal where product purity and chemical resistance are non-negotiable. With a fully PFA or PTFE-lined interior, it offers exceptional protection against aggressive media while enabling clean, residue-free discharge. This makes it particularly well-suited for use in pharmaceutical, biotech, and fine chemical processes. Its bottom-outlet configuration ensures thorough system emptying with no dead space, meeting stringent process safety and Clean-in-Place (CIP) standards.

Key features and benefits of BR22a Samson Pfeiffer Bottom Drain Ball Valves.

Key Features

The BR22a features a specialized bottom-outlet configuration that allows complete drainage of vessels or pipelines without leaving behind residue or stagnant media. This is essential for clean-in-place (CIP) systems and processes requiring high levels of hygiene and safety.

Key Features

With a seamless corrosion-resistant lining, the valve provides superior protection against aggressive chemicals and ensures purity in ultra-clean applications. This makes it ideal for industries like pharmaceuticals, fine chemicals, and biotechnology.

Key Features

The BR22a supports both manual operation and full automation via pneumatic or electric actuators. This versatility allows it to be seamlessly integrated into modern process control systems where precision and reliability are critical.

From bottom drain to multi-port configurations, Samson Pfeiffer valves are tailored for complex process demands. Their designs help minimise dead space and ensure full system drainage.

Get in touch

Samson Pfeiffer Ball Valves are commonly used in the chemical, pharmaceutical, semiconductor, and biotech industries, especially where corrosive or ultra-pure media are involved.

They are typically lined with PTFE, PFA, or PVDF, offering excellent chemical resistance and ensuring compatibility with aggressive and high-purity media.

Yes, these valves can be fitted with pneumatic or electric actuators, allowing for seamless integration into automated process systems.

Absolutely. Their non-porous linings and clean internal designs make them ideal for processes that require strict hygiene and contamination control.

Each model is tailored to a specific function:

BR20a: General-purpose ball valve with full lining.
BR26a: Compact design with robust shut-off features.
BR22a: Bottom drain valve for complete vessel or pipeline emptying.

Yes, many models feature full bore construction, allowing unrestricted flow and minimal pressure drop across the valve.

They are available in a wide range of sizes, typically from DN15 to DN150, depending on the model and application.

Yes, the PFA and PTFE linings offer excellent thermal stability, allowing use in a wide range of temperatures commonly found in process industries.

They can be supplied with flanged, threaded, or custom connections, and some are specifically designed for glass pipeline integration.

They combine German engineering precision, seamless linings, and modular design, all backed by the global reputation of the Samson Group.

While primarily designed for corrosive and clean media, certain models can handle lightly abrasive fluids, depending on process conditions.

They are manufactured by Pfeiffer Chemie-Armaturenbau GmbH, part of the Samson Group, known for its high standards of valve engineering and production quality in Germany.
