平板闸阀是一种关闭件为平行闸板的滑动阀。其关闭件是单闸板，闸板向阀座的压紧力是由作用与浮动闸板或浮动阀座的介质压力来控制。RAYS研制生产的平板闸阀具有弹性有预紧力，上、下游密封座同时密封的结构阀座、阀座有自清洗功能、阀门执行机构与阀门独立等特点。可以根据客户要求，闸板形式分带导流孔，不带导流孔，可调节闸板等形式。
通用铸钢闸阀是一种使用金属钢材浇铸成铸件加工的闸阀，主要用于管道系统中作为调节和截流装置。铸钢闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，只能作全开和全关，不能作调节和节流。
The Cryogenic Temperature and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
