Middle and low pressure forged steel globe valve

Middle and low pressure forged steel globe valve is a small diameter pipe gate valve manufactured by die forging process, which is used to cut off or connect the medium in the pipeline

Application
Middle and low pressure forged steel globe valve is a small diameter pipe gate valve manufactured by die forging process, which is used to cut off or connect the medium in the pipeline. Choose different materials, can be respectively suitable for water, steam, oil, nitric acid, acetic acid and other media.
Characteristic
• Body adopts full forging process, uniform structure, beautiful appearance, to avoid possible casting defects;
• Opening and closing parts are plug shaped valve disc, sealing surface is flat or conical surface, the valve disc along the center line of the seat for linear movement;
• The throttling use of the valve can be achieved by selecting the throttling disc;
• According to the connection mode is divided into three kinds: flange connection, screw connection, welding connection;
• Body materials, gaskets and fillers can be reasonably selected according to actual conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions;
• There are multiple operation modes for users to choose, mainly manual, bevel gear drive, pneumatic, electric, etc.
