About DQSV

DQSV is Xi’an Deqiansheng Valve Technology Co., Ltd. Its valve range includes slurry, lined, isolation, control and high-temperature types.

The duty comes first.

A valve cannot be specified by nominal size alone. The medium, design and operating range, solids content, connection and operating method determine which construction and materials are worth considering.

Our catalogue groups the supplied products by valve family. Use it to identify a starting point, then share the full project specification for review.
