PD44
擁有的計(jì)量、混合和分配閥
適用于微量雙組份材料
固瑞克 PD44 閥專用于配制少量的（0.005 到 5 毫升）水稀材料到糊狀粘稠材料。計(jì)量桿和機(jī)加工的密封件緊密配合，從而增加密封件的壽命。
功能：
? 專門設(shè)計(jì)，適用于雙組份材料的精確分配，包括環(huán)氧樹(shù)脂、聚氨酯、硅膠及大多數(shù)反應(yīng)性樹(shù)脂體系等
? 改進(jìn)的低粘度閥桿設(shè)計(jì)
? 桿式容積式計(jì)量
? 精確配比和點(diǎn)膠量重復(fù)性能
? 閥內(nèi)材料無(wú)硬化的潛在可能，也無(wú)須清洗
