Burkert Type 2100 pneumatically operated 2/2-way angle seat valve is specially optimised for decentralized process automation and fulfils tough criteria in process environments. Its unique design allows easy integration of automation units in all expansion stages, from electrical/optical position feedback to pneumatic control and integrated fieldbus interface. 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 characterised by its compact and smooth design, integrated pilot air ducts, protection classes IP65/67, NEMA Type 4X, and high resistance to chemicals.

Control Functions and Flow Direction

Flow Direction Below Seat

Only use flow direction below the seat for liquid media, gases, and vapours. As the medium is present under the swivel plate, the operating pressure contributes to the opening of the valve.

Flow Direction Above Seat

Only use flow direction above the seat for gases and vapours, and for valves with control function A (closed by spring force in rest position). As the medium is present above the swivel plate, the operating pressure contributes to the closing of the valve.

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.

ATEX Safety Instructions

For devices used in potentially explosive atmospheres (Ex area):

• Ensure that the device or system cannot be switched on unintentionally.
• The actuator and valve body must be grounded. If a plastic valve body is used, ground the actuator separately.
• Only use cleaning agents certified for explosive environments.
• Take appropriate measures to ensure that static electricity cannot build up in the potentially explosive area.
