GB Cast Steel Globe Valve With Flange Ends Stainless Steel
Production Description
● Globe valve products are designed and manufactured according to the national standard GB12235, with reasonable structure, reliable sealing, excellent performance and beautiful appearance.
● The valve disc and valve seat sealing surface are made of iron-based alloy surfacing or stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long service life.
● The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance and scratch resistance.
● Various piping flange standards and flange sealing surface forms can be used to meet various engineering needs and user requirements.
● The inverted seal is made of threaded connection seal seat or body surfacing of austenitic stainless steel, which is reliable in sealing, and the packing can be replaced every day without stopping the system conveniently and quickly without affecting the system operation.
● The selection of materials is exquisite, in line with relevant domestic and foreign standards, and the overall quality of materials is high.
● It meets the requirements of advanced standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance.
● The sealing pair is advanced and reasonable. The sealing surfaces of the gate plate and the valve seat are made of Stellite cobalt-based hard alloys with different hardnesses. The sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, anti- Good abrasion performance and long life.
● The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance, scratch resistance and wear resistance.
● The wedge-type elastic gate structure is adopted, the medium and large diameters are provided with thrust bearings, the friction force is small, and it is equipped with an impact manual, which can be opened and closed easily.
● Scale with thickness. The thickness is more than 10% thicker than similar globe valves, and it has strong compressive corrosion resistance.
Application Area
This valve is suitable for various industries such as petroleum, chemical, electric power, steel, mining, heating, etc.
The medium is water, oil, steam, acid medium and other pipelines under various working conditions.
