Control Valve manufacturer China Valve Industry offers Bellows Sealing Single-seat Control Valve in cast steel, scarf welded, JIS 10/16/20K. Bellows sealing single-seat control valve is a type control valve with top guide structure. The valve has compact structure, S-pattern channel, less pressure losses and wide control range. Bonnet adopting bellows sealing structure eliminates the possibility that medium leak out from movement clearance of the stem. For morphotropy and excellent aging resistance of bellows, the valve dose not have the aging of packing existing in packing sealing valve and temperature sensitivity. Bellows-packing double sealing structure has good reliability. For that, bellow sealing single-seat control valve is widely used in automatic control system for toxic, strong corrosive or radioactive medium. Parameter Nominal diameter: DN40-200mm. Nominal pressure: ANSI 125, 150,300Lb; JIS: 10, 16, 20K Face to face: scarf welded, bonnet welded Working temperature: -17~230℃ Materials Body: cast steel, stainless steel, stellite alloy, titanium alloy Packing: PTFE, flexible graphite Diaphragm: rubber
