Shanghai Dacheng Special Control Valve Co., Ltd. — a control valve technology company built on engineering knowledge, not factory scale.
Dacheng specializes in special-service control valves, with the eccentric rotary plug valve (camflex type) as our flagship product line. Our engineers handle every step that decides whether a valve works in service: application analysis, sizing calculation, trim design, material selection and inspection planning.
Manufacturing is executed by partner factories that pass our audits and work under our technical dossiers and inspection procedures. This model keeps engineering sovereignty — the knowledge, the data and the accountability — inside Dacheng.
We serve chemical, fluorine-chemical and industrial utility customers, including large plant groups with demanding qualification processes.
• Sizing-verified proposals — data first, quotation second
• Technical dossiers and QC records with every valve
• Engineering support across the whole valve lifecycle
• Honest communication: we are a technology company, and we say so
ZSPF/ZSNF series, DN25–DN400, up to 6.4 MPa — for slurry, coking and severe-service control loops.
Solutions for elevated temperature and pressure services are available within our engineering capability range.
Precision low-flow regulation solutions can be engineered on request with your process data.
Our lead valve designer has served as a senior technical executive at renowned valve companies both in China and abroad. Decades of structure design, application engineering and field service experience come together in every sizing we deliver.
A core group of veteran assembly technicians carries out assembly, adjustment and bench testing, making sure every valve performs on the stand exactly as the design intends.
