·内部装有主阀和副阀的双阀座差压机构和SCCV关闭系统，体积小而排量大。
·不锈钢内件安装在阀盖上，易于维修保养。
·背压率可达90%。
·汽水分离可靠，阀内始终处于水封状态，有效阻止蒸汽泄漏。 |

normal style="MARGIN: 0cm 0cm 12pt; TEXT-ALIGN: left; mso-pagination: widow-orphan" align=left>双阀座差压机构和SCCV关闭方式
SCCV关闭方式和双阀座差压机构安装在同一单元内，使用寿命长。当凝结水量增大时，吊桶失去浮力使得机构反向密封而产生压差，主阀开启而获得大排量，用汽设备迅速启动，最大限度地提高加热设备的热效率。
