\n
Applications<\/p>\n
<\/div>\n

Widely used in power plant, heating engineering, thermal oil circulation, chemical processing, pharmaceutical and environmental protection pipeline systems. Especially suitable for high\u2011temperature steam, viscous medium and process pipelines requiring frequent opening\/closing and low pressure loss.<\/p><\/div>\n<\/div>\n

\n
Working Principle<\/p>\n
<\/div>\n

Y Type Bellows Seal Globe Valve adopts 45\u00b0 Y\u2011shaped flow passage structure. The valve disc lifts and lowers linearly to realize fluid cut\u2011off and throttling. The inclined channel makes medium flow smoother and reduces turbulence and pressure loss. The fully welded metal bellows isolates the valve stem from internal medium, completely eliminating traditional packing leakage, ensuring long\u2011term stable and safe operation.<\/p><\/div>\n<\/div>\n
