HDA500 Series Multistage Pressure Drop Angle Regulating Valve

Categroy: Control Valve

HDA500 series multi-stage pressure drop anngle regulating valve is suitable for the regulation and isolating control of high temperature and high pressure fluid. HDA500 series multi-stage pressure drop angle regulating valve adopts multi-stage pressure drop sleeve, which completely controls the flow rate of fluid flowing through the valve trim, greatly reduce the noise generated by high differential pressure gas or steam, and it can also effectively prevents cavitation of liquids. It is an economical angle valve that has low cavitation damage, low noise and stable fluid control. This series of regulating valve can be available of bellows type, extended bonnet type, high temperature type and steam jacket type.
