Burkert 20000614 (Type 2100) is a pneumatically operated 2/2-way angle seat valve specially optimised for decentralized process automation. It fulfils tough criteria in process environments, offering high flow rates and a long service life. Its unique design allows 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 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.

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.

Water Hammer Hazard

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.

Operating Limits

In addition to the maximum operating pressures, the operating range of Burkert process valves is limited by the nominal pressure according to the relevant standard.

ATEX / Explosion Protection

For devices with ATEX/IECEx approval (e.g., EPS 18 ATEX 2 008 X II 2G Ex h IIC T4…T2 Gb / II 2D Ex h IIIC T135°C…T300°C Db), ensure proper grounding of the valve body and actuator. Do not open the spring-loaded actuator cover. Observe all specific conditions for safe use in potentially explosive atmospheres as detailed in the operating instructions.
