Medium and low pressure cast steel globe valve
Middle and low pressure cast steel globe valve is a widely used valve to open and close various pipeline media, with short opening and closing time, good sealing characteristics
Application
Middle and low pressure cast steel globe valve is a widely used valve to open and close various pipeline media, with short opening and closing time, good sealing characteristics. Choose different materials, can be respectively suitable for water, steam, oil, nitric acid, acetic acid and other media.
Characteristic
• The shell is formed by casting process;
• The opening and closing part of the globe valve is a plug shaped disc, the sealing surface is planar, conical or spherical, the opening and closing part is driven by the stem, and the valve moves up and down along the axis of the seat;
• Straight down of valve stem, easy to open and close, slow down instantaneous friction, powerful protection of seals, prolong service life;
• Can use welding end and various pipe flange standards and flange sealing face types to meet various engineering needs and user requirements;
• 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.
