Product Overview
The Pureline PLMV-P 25A is a pneumatically actuated diaphragm valve engineered for precise on/off and modulating control of neutral and aggressive media in industrial process lines. Manufactured by Pureline, this valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the working fluid from the valve bonnet and actuation mechanism. The PLMV-P 25A features a 25A (DN25) nominal port size and is designed for reliable shutoff and flow control in systems requiring high purity, corrosion resistance, and minimal dead volume. Its pneumatic actuator ensures rapid response and stable operation in automated process environments.

Engineering Features & Advantages
- Precision Performance: The diaphragm design provides bubble-tight shutoff and excellent throttling characteristics with minimal pressure drop, ensuring accurate flow control in critical process lines.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust pneumatic actuator and durable diaphragm materials that resist wear, corrosion, and chemical attack.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing piping or control systems.
- Contamination-Free Operation: The isolation of the working fluid from the valve stem and actuator prevents media contamination and extends service life in hygienic and high-purity applications.
Typical Industrial Applications
The Pureline PLMV-P 25A is ideal for a wide range of heavy industrial and process scenarios, including chemical dosing and transfer systems, water and wastewater treatment plants, pharmaceutical and food processing lines requiring sanitary operation, and general industrial automation where reliable pneumatic on/off control of aggressive or viscous media is essential.
