KKI630S 三杆阀

三杆阀主要用于空气分离装置分子筛吸附系统中。

主要有以下优点：

1、阀板与阀座在开启和关闭初始平移，密封面无摩擦，寿命长；

2、密封面垂直与管道，有自清洁功能；

3、执行机构设定压力，实现最大开启压差保护，避免高压差气流意外冲击分子筛床层。

Three Lever valve are mainly used in the molecular sieve adsorption system of air separation plants. 

Advantages are as follows:

1. During opening and closing stages, the initial movement of the valve disc is parallel from the valve seat. No friction on the sealing surface contributes to a long life;

2. The sealing surface is perpendicular to the pipe. It has then the selfcleaning function;

3. The actuator sets the pressure to achieve the Maximum Open Differential Pressure Protection function in order to prevent accidental impact of high pressure differential airflow on the molecular sieve bed.
