This is an instruction manual for the 2080 type pneumatic valve
This manual provides operating instructions and safety guidelines for the Bürkert 2080 pneumatic bellows valve. It covers intended use, safety precautions, installation procedures, maintenance, and technical specifications. The valve is designed for controlled flow of liquids and gases and must be used with approved components and in accordance with specified conditions. Maintenance includes periodic bellows replacement to prevent leaks and ensure reliable operation.
The valve features a piston actuator with PTFE bellows, stainless steel body, and modular design. It operates with compressed air (4.5–10 bar) and supports DN 4 to DN 10 orifice sizes. Installation requires proper alignment, sealing, and securing to prevent unintended activation. Maintenance must be performed by authorized technicians with appropriate tools and safety precautions.
