Products and services that meet fluid control requirements

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
