Product Overview
The Bürkert Type 8802 is a modular continuous control valve system engineered for precise regulation of neutral and aggressive media in industrial process and pneumatic control loops. Designated by model code 8802 2300 A 25.0 PTFE VA D29 (part number 20018598), this configuration combines a pneumatically actuated control valve body with a PTFE-lined, stainless steel (VA) wetted path, delivering accurate modulating control rather than simple on/off switching. The valve operates on a balanced plug-and-seat principle, where a pneumatic pilot signal positions the actuator stem proportionally to modulate flow through the valve orifice. With a nominal line size of DN25 and a PTFE/VA construction, the unit is purpose-built for corrosive and high-purity service in continuous process environments, integrating seamlessly into distributed control systems (DCS) and PLC-driven process lines.

Engineering Features & Advantages
- Precision Performance: Continuous proportional positioning of the valve plug enables accurate flow, pressure, or temperature modulation, eliminating the cycling losses associated with on/off control and improving overall process stability.
- Corrosion-Resistant Construction: The PTFE-lined wetted path and stainless steel (VA) body provide excellent chemical resistance, making the valve suitable for aggressive, neutral, and high-purity media where standard elastomeric seals would degrade.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust pneumatic actuator designed for high cycle life and consistent stroke repeatability.
- Modular System Architecture: The Type 8802 platform allows flexible combination of valve bodies, actuators, and positioners, simplifying spare parts management and future reconfiguration.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original BURKERT standards, allowing straightforward retrofit into existing hydraulic systems without rework.
