The Armstrong Bellows Sealed Globe Valve features a double wall stainless steel bellows at the stem seal, and a graphite packing seal accessory to prevent leakage. The finely polished planar sealing between the valve and the seat ensures long-term, reliable, operation whether the stem is moving or not.
波纹管密封截止阀
????????????????????????????????????????????????????????????????????????????????????
阿姆斯壮波纹管密封截止阀采用双重组合密封，以双层不锈钢波纹管作为阀杆密封元件，同时以石墨填料作为二次辅助密封，真正杜绝泄漏。阀瓣与阀座的密封，进一步确保了阀杆处动态和静态密封性能的高度可靠，便其在各种方位下都能表现出卓越的密封性能。另外，在高压或大口径工况下采用双阀瓣截止阀可大大减小开关操作扭矩，有效解决启闭难的问题。
