Bellows valve

105 bellows valve Name: bellows valve; also known as: no leak valve, Falan Bo bellows valves, bellows globe valve threaded Model: WJ41H use - bellows valve is a new type of shut-off valves This valve is a dual seal design, the sealing performance than conventional cut-off valve has a more reliable superiority. Bellows globe valves length of life, depends largely on its core components - bellows. I am using the world's advanced process technology bellows as the main components, greatly improving the resistance to fatigue and life bellows globe valves, bellows globe valves make high temperature, low temperature, highly toxic, strong corrosion, energy and other fields have a significant The insight of the unique advantages. Advantages - 1. bellows globe valves, the key components of metal bellows, the lower end of the stem assembly automatic roll welding, automatic roll welding the upper end of the connecting plate between the fluid medium and atmosphere to form a metal barrier, ensuring valve pole zero leakage; 2. valve tapered design, sealing surface and the media into a streamlined, better sealing performance, longer life; 3. dual seal design (bellows + filler) if bellows failure, the valve filler rod will avoid leakage, in line with international standards seal; 4. bonnet comes with grease fittings, can be directly stem, nut and sleeve for lubrication, unlike traditional only lubricate thread; 5. ergonomically designed hand wheel, longer life, easy operation and convenient, more secure and reliable; Parameters - Temperature: -20 ℃ ~ 350 ℃ applicable Nominal: PN1.6 ~ 4.0Mpa Diameter: DN15-DN400 Applications: Hot oil system, steam system, hot and cold water systems, etc.
