ANSI BELLOW SEAL GLOBE VALVE

ANSI 150LB Bellow Globe Valve uses bellows as the valve stem sealing element, which can prevent the valve stem from leaking to prevent the medium from leaking. No fluid loss increases energy efficiency, improves production equipment safety, reduces maintenance costs and maintains maintenance costs. It also ensures a clean and safe working environment. It is most suitable for pipelines containing steam, flammable, explosive media, heat transfer oil, high purity, toxic and other media. The globe valve is used for rated pressure 150LB-300LB, and the connecting flange is ANSI B16.5. At high temperature, the stem does not come into contact with the medium, so there will be no stem leakage. At the same time, ensure sufficient strength and toughness, allowing you to change tens of thousands of times. The handwheel is ergonomically designed for longer service life and easy operation.



ANSIStandard Bellow Sealed globe valve ( Os & Y Type ) is applied to various kinds of working conditions of pipelines such as petroleum, chemical industry, pharmacy, fertilizer, and power industry, etc, under nominal pressure in the PN1.6-40 MPa and operating temperature at -20 - 350ºC, that is used to cut off or connected to the pipeline medium.

Product main advantages:
1. bellows globe valves, the key components of metal bellows, the lower end of the stem assembly with automatic roll welding, the upper end of the connecting plate automatic roll welding, between the fluid medium and the atmosphere to form a metal barrier, to ensure zero stem leakage ;
2. The tapered design of the valve, the sealing surface and the dielectric into streamlined, better sealing performance, longer life;
3. The dual seal design (bellows + fill) if the bellows failure, stem packing will prevent leaks, and sealed in accordance with international standards;
4. bonnet comes with a grease fitting directly on the stem, nut and bushing lubrication, unlike conventional lubricating only thread;
5. ergonomic hand wheel, longer life, easy operation and convenient, more secure and reliable;
Applications: hot oil system, steam system, hot and cold water systems.
