Oxygen globe valve: copper alloy globe valve

Oxygen globe valve is one of the special valves for oxygen pipeline network. It not only has the function of ordinary globe valve, but also has the characteristics of good flame retardancy, good conductivity, fast heat transfer, compact structure, oil proof, safety and reliability. With the development of metallurgical industry, oxygen globe valve and oxygen ball valve are widely used in iron and steel, metallurgy, medicine, chemical industry and so on.

Bellow Seal Valves:Gate,Globe Valve

A valve with a bellows to seal off the stem enclosure is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. The bellows is welded to the stem and to the bottom of the bonnet.
Supplier: Sangong Valve, China
Manufacturer: Shop in Wenzhou Oubei Industrial Park

Bellow seal valve is designed with bellow welded onto the bonnet and stem, so that when the stem travels drive the below expansion or decompression. It inherently eliminate the conventional design of possible stem packing leakage. SGV bellow sealed valves can achieve truly zero leakage; ideal for stringent leakage-free application like toxic and flammable services. Bellow seal valve is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. Continue reading “Bellow Seal Valves:Gate,Globe Valve”
