Brass globe valve is a type of globe valve series product. Compared with traditional ductile iron and cast steel globe valves, brass globe valves are mainly small valves made of brass, also known as copper zinc alloy, which provides good corrosion resistance and extends the service life of the valve.Brass globe valves are widely used in marine valves and have advantages that ordinary globe valves do not possess.Due to the relatively short opening or closing stroke of the valve stem and its highly reliable shut-off function, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for use as a cut-off, regulating, and throttling device.
From the perspective of structure and principle
brass globe valves control the on/off of the medium by driving the valve disc vertically to the valve seat through the valve stem to perform lifting and lowering movements.When closed, the valve disc is tightly attached to the valve seat, which can effectively cut off the flow of the medium. 1.Compared to gate valves, brass globe valves close more tightly. When a gate valve is closed, there may be a certain gap between the gate and the valve seat, while brass globe valves have better sealing effects due to their structural characteristics, especially suitable for pipeline systems with strict leakage requirements.For example, in some small water supply pipelines, brass globe valves can effectively prevent water dripping. 2.Compared to ball valves, brass globe valves have more precise flow control characteristics.During the opening process of a ball valve, the flow rate changes relatively suddenly, while a brass globe valve can adjust the medium flow rate more finely through the gradual lifting and lowering of the valve disc, which is advantageous in some chemical experimental equipment pipelines that require high flow control accuracy.
