The Series 33000-2 stands as a pinnacle of engineering in the world of ball valves for professional A1-A2L-A3 refrigeration systems. Its strength originates from a flawless construction, with a yellow brass body that is pin-secured, thus eliminating the need for welding. This approach significantly enhances the product's safety by preventing potential seal damages associated with the welding process and avoiding cracks inherent in brass-to-brass welding.

Each valve incorporates a control stem made of AISI 303 stainless steel, promising not only extended durability but also steadfast reliability in everyday operations. This material choice signifies a dedication to lasting quality. Furthermore, the Series 33000-2 benefits from a double O-ring seal in HNBR on the control stem, assuring a secure seal and further augmenting the safety of the valve.

A vital feature is the brass cap, furnished with a seal, ensuring continued tightness and seal integrity even if the stem's sealing gaskets are accidentally damaged.

The culmination of the Series 33000-2's excellence is its rigorous 100% testing protocol, executed using a modern helium plant. Each valve is marked with a date and serial number, confirming its successful testing and facilitating the traceability of its performance data over time. This strict quality assurance results in a product you can rely on for exceptional performance, capable of withstanding operating pressures of 52 bar (753 psi) and temperatures ranging from -40°C to +150°C (-40°F to +302°F).

Thus, the Series 33000-2 emerges not just as a product but as an emblem of safety, dependability, and cutting-edge innovation in professional refrigeration.
