Pneumatic Boiler Blowdown Control Valves, DN25-DN50, 1500 LB

Key Specifications / Features

Available in port sizes ranging from DN25 to DN50 (1 Inch to 2 Inch) and pressure ratings from PN25 to PN32 (Class 1500 LB to 2500 LB), this pneumatic boiler blowdown control valve is engineered to handle water, steam, and gas mediums. It serves as an anti-cavitation multi-stage pressure reduction valve, featuring a specially designed trim that facilitates incremental fluid pressure reduction, thus controlling fluid velocity to prevent cavitation damage. The trim's separable throttling part enhances sealing face protection, while the hardened surface treatment ensures durability with a hardness of approximately HRC70. Notably, a large notch on the plug surface prevents blockage from granular fluids. With excellent erosion resistance and prolonged service life, this valve offers an optimal solution for intermittently eliminating insoluble sediments and impurities from boiler water in power plants.
