D381X-16Q Grooved Type Gear Butterfly Valve
The D381X-16Q Grooved Type Gear Butterfly Valve stands out for its low pressure drop and efficient flow control. When fully open, the only resistance to flow is the disc itself, making it ideal for use in fluid pipelines for water supply and drainage, as well as systems like fire protection, HVAC, water treatment, municipal engineering, and shipbuilding. It uses grooved clamp connections, which are more material-saving than traditional flange or wafer styles, aligning with China’s energy-saving and emission reduction policies.
This valve is easy to install—fast, firm, and reliable—and helps reduce labor and material costs. For detailed options, explore the butterfly valve catalog or view the full industrial valve range at the XH Spark Valve website.

-
Open the bypass valve before operating.

For frequent use, clean and lubricate at least once a month.
