Use special support frame and reduce the heat conduction effects between valve and actuator in maximum. Greatly lower actuator's heating surface.
使用特殊支架，最大限度地减少了阀门体与油动机之间的热传导效应，使油动机受热面积大大减少。
Medium pressure increases toward the valve seat surface and oblique cone sealing surface squeeze is tightening, sealing the better.
正向介质压力增大时阀板斜圆锥表面与阀座密封面挤压越紧，密封效果越好。
Caution: the sealing surface for the diaphragm on the top flange of the valve body receives special factory preparation to enhance sealing with PTFE diaphragms.
警告：用于阀体法兰上的隔膜的密封面在工厂受到特殊的处理，以强化聚四氟乙烯隔膜的密封性能。
