Product Overview
The Burkert Type 2000 (Model 2000 A 25.0 PTFE VA / Part No. 00178674) is a pneumatically actuated angle seat valve engineered for precise, high-cycle control of neutral and aggressive media in industrial process systems. Manufactured by Burkert, a global leader in fluid control technology, this valve utilizes a piston-driven pneumatic actuator acting on a spring-loaded valve spindle to provide reliable on/off and modulating flow control. The angled seat body geometry delivers superior flow characteristics with minimal pressure loss, making it an ideal solution for demanding process lines requiring fast response, high flow rates, and long service life. The PTFE (Polytetrafluoroethylene) sealing system and VA (stainless steel) body construction ensure broad chemical compatibility and resistance to corrosive media, positioning this valve as a critical component in hygienic, chemical, and industrial fluid handling circuits.
