Ultra-low temperature ball valve

Product overview: 

 Low-temperature valve is a kind of valve used under low-temperature working conditions. The temperature is usually below -50℃, and most of its working medium is flammable, explosive, highly toxic and permeable substances, such as ethylene, liquid oxygen, liquid hydrogen, LNG and LPG. Its valve structure and material selection have the following requirements: long working life; cold preservation and heat dissipation; abnormal pressure-up structure design; uniform valve body wall thickness; filler anti-freeze; fire prevention and anti-static, etc. 

 Pressure range: PN16~PN420, 150LB~2500LB 

 Caliber range: DN15~DN350 

 Temperature range: -196℃~-50℃
