Burkert Type 2101 (Model 20032397) is a pneumatically operated 2/2-way globe valve ELEMENT designed for decentralised process automation. The valve features a stainless steel body and a self-adjusting V-seal packing gland, ensuring high seal tightness and a long service life. It is suitable for controlling the flow of liquid and gaseous media, including steam, water, alcohols, oils, and neutral gases. The highly integrated system of valve and automation unit is characterised by its compact design, integrated pilot air ducts, and high resistance to chemicals.

Features

• Compact design with seamless 360° actuator rotation.
• Long service life with maintenance-free operation under normal conditions.
• Easy integration of automation units with the ELEMENT system.
• Stainless steel valve body with welded, flange, threaded, or clamp connections.
• Suitable for steam sterilization and aggressive media.

Control Functions

The valve operates with different control functions depending on the configuration:

• Control function A (CFA): Pneumatically operated 2/2-way on/off valve, normally closed by spring force.
• Control function B (CFB): Pneumatically operated 2/2-way on/off valve, normally opened by spring force.

WARNING

Risk of damage due to bursting pipes and bursting equipment when the flow is above the seat. In the case of liquid mediums, water hammer can occur causing pipes and the device to burst. Do not use valves with flow above the seat for liquid mediums.
