API 602 Standard 150lb - 2500lb Cast Steel Stainless Steel Forged Globe Valve
Product Introduction:
Forged steel globe valve is a common valve device that uses forging technology to forge the valve body material into shape, which has certain characteristics as precise flow control, high pressure capability, reliable sealing, logevity and low maintenance,
The American standard API 602 forged steel globe valve is suitable for cutting or connecting pipeline media in various working conditions such as petroleum, chemical, and thermal power plants with ANSI Class150~2500 and working temperature<600 ° C. Applicable media include water, oil, steam, etc. The operating methods include manual, gear transmission, electric, pneumatic, etc.
The American standard forged steel globe valve is a commonly used shut-off valve, mainly used to connect or cut off the medium in the pipeline, and is generally not used to regulate flow. The cut-off valve is suitable for a wide range of pressure and temperature. This valve is suitable for small diameter pipelines, with sealing surfaces that are not easily worn or scratched, good sealing performance, small valve disc travel during opening and closing, short opening and closing time, and small valve height.

Product features:
1. The product is designed and manufactured according to API standards, with reliable sealing, excellent performance, and can be used in conjunction with imported equipment.
The sealing of the gate and valve seat above 2.600Lb is made of Stellite cobalt based hard alloy overlay welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, with good scratch resistance and long service life
3. The valve stem has undergone quenching and surface nitriding treatment, and has good corrosion resistance and scratch resistance.
4. Adopting a wedge-shaped elastic gate structure and equipped with rolling bearings for medium and large diameters, the opening and closing are easy.
5. The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
6. The middle chambers of 6.1500LB and 2500LB adopt a pressure self tightening sealing structure. The sealing performance increases with the increase of internal pressure, and the reliability is high.
7. The reverse seal is made by connecting the sealing seat with stainless steel threads or welding austenitic stainless steel on the body. The reverse seal is reliable, and filling replacement and maintenance can be carried out without stopping the machine, which is convenient and fast without affecting the system operation.
