Bürkert Pneumatically Operated 2/2-WAY Globe Valve ELEMENT for Decentralised Automation

The Type 2101 globe valve is specially optimised for decentralised process automation and meets all practical requirements even under difficult operating conditions. Its unique design allows easy the 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.
