Buy Knife Gate Valve ZDCS-D 0.25–0.8MPa PP/PVC Body Flanged Pneumatic Operated
The ZDCS-D Automatic Pneumatic Knife Gate Valve by VALVEHU is engineered for precise shut-off in systems handling corrosive, acidic, or particulate-laden fluids. With a compact design and air-blow assist feature, this knife gate valve is an ideal solution for low-pressure industrial processes requiring clean closure and debris flushing.
This model is built using corrosion-resistant plastic materials such as PP, ABS, PVC, and POM, ensuring chemical compatibility across a wide range of aggressive applications. It supports nominal pressures of 0.25, 0.6, and 0.8 MPa, making it suitable for medium and light industrial flows. The valve is structurally optimized with flanged ends for quick installation and replacement in pipeline systems.
The internal air-blow mechanism helps remove residual particles from the sealing area during closure, enhancing operational efficiency and reducing maintenance frequency. Each unit undergoes rigorous testing with seal test pressures up to 0.88 MPa and is designed in accordance with national standards GB/T23300-2009 and HG/T20592-2009.
With a temperature tolerance from 20°C to 60°C, the valve ensures stability and consistent performance in ambient and controlled industrial conditions. It also features stainless steel mesh filtering (A240 or 304), extending durability in fluid systems where sediment or solid debris is present.
For chemical, wastewater, mining, and similar process applications requiring reliable shut-off with minimal fluid retention and low leakage, this knife gate solution is highly effective.
If you’re looking for a specialized valve to handle corrosive or non-standard fluids, the ZDCS-D is an ideal match. Contact our expert team at VALVEHU in China to get tailored support and technical advice for your valve selection.
