The pneumatic boiler blowdown control valve is a multi-stage pressure reduction valve designed to prevent cavitation. Its specialized trim reduces fluid pressure in stages, controlling fluid velocity to avoid cavitation damage. The throttling part is detachable from the sealing face for enhanced protection. Hardened trim surfaces ensure excellent erosion resistance and durability, with a notch on the plug surface to prevent blockages from granular fluids. Ideal for power plants, it efficiently removes insoluble sediments and impurities from boiler water intermittently, ensuring long-term reliability and performance.
