BURKERT Type 2100 (SKU 20044787) is a pneumatically operated 2/2-way angle seat valve specially optimized for decentralized process automation. It fulfills tough criteria in process environments, offering high flow rates and a long service life. The specific 20044787 model features a stainless steel body with a weld end connection (DN 32), a PEEK seat seal, and operates as normally closed (Control function A). It handles operating pressures up to 19.5 bar and medium temperatures ranging from -10 °C to +230 °C.

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.

Operating Limits

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

DANGER

Explosion Hazard due to Electrostatic Charge! If the device is used in a potentially explosive atmosphere (ATEX), sudden discharge of electrostatically charged devices or individuals presents an explosion risk. Ensure appropriate measures are taken to prevent electrostatic buildup. Ground the actuator and valve body appropriately.
