结构简单紧凑,流道通畅,流量特性曲线精度高,稳定可靠,经济实用,维修方便。在常规型的基础上,采用模块化扩展设计开发。
采用标准化、通用性、模块化和互换性原则开发。不同通径的阀门最大限度地提高了零件质量互换性、通用性和易于维护。这确保了较低的运营成本。

锻钢件的质量高于铸钢件,能承受较大的冲击力。其塑性、韧性等力学性能均高于铸钢件。锻钢截止阀的通径一般不大于DN80,多数为小通径设计。与相同直径的铸钢截止阀相比,流量略低,但其所能承受的压力和温度范围均高于铸钢截止阀,其密封性能远优于铸钢截止阀,使用寿命更长。像其他截止阀一样,它们受到介质流动方向的限制。锻钢截止阀按安装位置可分为直通式截止阀(型截止阀)和直流式截止阀(y型截止阀)。
硬密封蝶阀是由我公司新开发的长寿命、节能型蝶阀。它由阀体、蝶板、密封圈、传动机构等主要部件组成。其结构采用二维或三维偏心原理设计,弹性密封或硬软多层次密封兼容的加工新工艺,使蝶阀在运行时,减少其扭矩,达到省力、节能之功效。同时确保蝶阀整体的抗腐蚀、耐高温、抗磨损的可靠性。常用的硬密封蝶阀有对夹式蝶阀、凸耳式蝶阀和法兰式蝶阀。
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.
