The new generation rotary globe valves type BR 33 are the result of co-operation between German firm - P+W Systeme GmbH and Polish one - Zakłady Automatyki Polna S.A.. Maximum flexibility in terms of materials and variety of design variations, and also high level of quality have caused that these valves are used in many industrial sectors including : chemical proces-sing, petrochemicals, refining, flue gas desulfuri-zation, heat and power engineering, paper industry, food processing, salt extraction and mining.
