Product Description
1. Globe valve achieves full open flow and full close shut off of pipeline medium through disc vertical lifting movement. It can be used for throttling regulation with special structural design.
2. Streamlined flow passage is adopted inside valve body, featuring short stroke and fast response.
3. Disc contacts seat face to face for sealing, delivering high sealing precision and strong differential pressure resistance.
4. The product is designed in compliance with API 600, ASME B16.34, BS 1873 standards.
5. Various materials for body and bonnet as well as complete set of valve trim are available upon request.
6. The valve is widely applied as shut off device for pipelines carrying water, air, steam, natural gas, oil and other media to realize medium cut off and isolation.
Features & Benefits
1. Product Design：Streamlined flow passage, outside screw and yoke with bracket and bolted bonnet.
2. Trim Feature：Loosely connected disc. Double disc structure is available for high temperature and high pressure working conditions.
3. Sealing Performance：Sealing face can be machined into flat or conical configuration. Sealing face is hard faced with cobalt base hard alloy for good wear resistance, corrosion resistance and anti galling property. It provides reliable sealing performance and long service life.
4. Stem Safety Structure：Forged T head loose joint stem is equipped with back seat structure for reliable sealing. It eliminates risks of stem ejection and over travel and maintains safe performance under fire condition.
5. Stem Feature：Treated by quenching and tempering plus surface nitriding process for excellent corrosion resistance and anti galling property.
6. Operation Feature：Rising stem. Rolling bearings are equipped for medium and large size to achieve easy opening and closing.
7. Pressure self sealing bonnet structure is adopted for valve cavity under high temperature and high pressure service. Bonnet sealing performance improves along with pressure rise to guarantee reliable tightness.
8. Material Combination Feature：Component material, flange standard, flange face type and butt weld end dimension can be reasonably selected according to actual working condition or user requirements.
