Burkert 20114732 Type 2100 pneumatically operated 2/2-way angle seat valve is specially optimised for decentralized process automation and fulfils the 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

Control function A (CF A) Pneumatically operated 2/2-way on/off valve. Flow direction below seat. Normally closed by spring force.

Risk of damage due to bursting pipes

Do not use valves with flow above the seat for liquid mediums. In the case of liquid mediums, water hammer can occur causing pipes and the device to burst.

Principle of Operation

Flow direction below the 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.

Installation Position

The installation position is as required, preferably with the actuator in an upright position. Protect the device from electromagnetic interference, UV radiation, and weather conditions when used outdoors.
