5819315416 一体式保温球阀 DN20-DN200 型号:BQ41H/F/PPL 产品说明
温下会凝固的高粘度介质。
由于采用整体式结构,因而保温球阀比一般球阀体积更小,重量更轻,且无外漏,密封性能良好,夹套采用碳素钢管焊接比铸造的更加耐压牢固。
For the monolithic construction is applied in design the product, the jacket valve with favorable sealing performance features smaller configuration and weight than traditional ball valves without leakage. More overpressure-resistant and firmer capacities are also
enjoyed by the jacket made through carbon steel welding than that through casting.
