·对夹式球阀产品详情

对夹式球阀产品参照意大利产品的特点，与普通球阀相比，具有结构长度短、重量轻、安装方便、节省材料等显著的优点。对夹保温夹套球阀保温效果好。此外，阀座采用弹性密封结构，密封可靠，启闭轻松。设有耐火结构，万一发生火灾时，仍然能够可靠操作并具有良好的密封性。根据用户需要，可设有防静电结构。设置了90°开关带孔定位片，根据需要可以加锁，防止误操作。

对夹式球阀产品用途：
对夹式球阀及对夹保温夹套球阀适用于Class150、PN1.0～2.5MPa，工作温度 29~180℃(密封圈为增强聚四氟乙烯)或 29~300℃(密封圈为对位聚苯)的各种管路上，用于截断或接通管路中的介质，选用不同的材质,可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。
适用介质：水、气、油品、天然气和酸碱腐蚀性介质。
适用温度：-20～150～300℃
驱动方式：手动、气动、电动等。
公称压力：1.6～2.5MPa
