Burkert 20106730 (Type 2100) is a pneumatically operated 2/2-way angle seat valve specially optimized for decentralized process automation. It fulfills tough criteria in process environments, allowing easy integration of automation units in all expansion stages, from electrical/optical position feedback to pneumatic control and integrated fieldbus interfaces. Maximum service life and tightness are achieved by the proven self-adjusting V-seal packing gland. The highly integrated system of valve and automation unit is characterized by its compact and smooth design, integrated pilot air ducts, protection classes IP65/67, NEMA Type 4X, and high resistance to chemicals.

Key Features:

• High flow rates and long service life
• Easy integration of automation units with ELEMENT
• Flow-optimized stainless steel valve body with sleeve, clamp, or weld connection
• Suitable for steam, water, neutral gases, alcohols, oils, fuels, hydraulic fluids, salt solutions, alkalis, and organic solvents

Control Functions and Flow Direction

WARNING: Risk of damage due to bursting pipes

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.

Flow direction below the seat (for liquids, steam, and gases) As the medium is present under the swivel plate, the operating pressure contributes to the opening of the valve.

Flow direction above the seat (for steam and gases) As the medium is present above the swivel plate, the operating pressure contributes to the closing of the valve. The operating pressure also supports the sealing of the valve seat.
