Technical Data
Working principle
Axial flow control valve refers to the streamlined symmetrical and unrestricted flow path between the valve inner and outer body. Accurate control features make the valve suitable for applications that require high pressure drop and high fluid velocity in all areas of the flow control task. The inherent capacity of the axial flow control valve is very high compared to conventional globe control valve designs and enables the selection of a smaller valve size. Alternatively, the higher capacity can be used to minimise pressure drop over the valve or to provide for special features, such as a modified control characteristic, additional noise control, anti-cavitation or awider operating envelope for future process changes.
Valve Design
Multi stage sleeve structure Pressure regulating is carried out through multi-stage sleeve of a series of small holes, and in the middle of the multi-stage sleeve to control the flow rate, energy dispersion is controlled, so that the noise is very low. At the same time, the pressure adjustment is done through the center of the sleeve.
Sleeve classification
Valve inner surface treatment
To improve the resistance to wear and resistant corrosion resistance, rack, a valve core, a sleeve all through the super coating processing (QPQ) and the surface hardness can be reached HV is equal to or more than 1100, guaranteeing stability under harsh conditions and long service life.
