Flow Control: For certain media, especially liquids, controlling flow rate may be crucial. In such cases, consider the flow control performance of the knife gate valve and the potential need for additional flow control devices.

knife gate valve

Media Temperature and Pressure: Different media may have varying temperature and pressure requirements. Ensure that the knife gate valve's materials and design are suitable for the media's operating temperature and pressure range.

knife gate valve

Follow Manufacturer's Recommendations: Manufacturers typically provide information on the suitability of knife gate valves for different media and maintenance recommendations. Always follow the manufacturer's guidelines and advice to ensure safe operation of the valve with various media.
