詳細(xì)介紹

球座閥，于蒸汽和水的流量控制，尺寸從1/2到4英寸，可選兩通和三通

2000VA/3000WA系列 Hi-Flow?氣動(dòng)薄膜調(diào)節(jié)閥是結(jié)構(gòu)簡(jiǎn)單，牢固耐用的高流通能力單座調(diào)節(jié)閥。它的應(yīng)用范圍廣，在同類型的同尺寸調(diào)節(jié)閥中，它具備更高的流通能力。
不僅僅是它的流通能力高，而且他能夠做到全范圍50：1的精確控制。高質(zhì)量的材質(zhì)，精密的機(jī)械加工和嚴(yán)格的性能測(cè)試可保證長(zhǎng)期的穩(wěn)定性和耐用性。采用PTFE的V型環(huán)和密封圈來(lái)減少摩擦阻力并保證在高壓操作中無(wú)泄漏。閥體可選用黃銅，316不銹鋼，內(nèi)件采用316不銹鋼，全焊接的結(jié)構(gòu)可保證產(chǎn)品的耐用和耐腐蝕能力。
