DeZURIK 使用寿命延长型不锈钢铸造刀闸阀设计符合 MSS-SP81 标准并为极粘稠的腐蚀性、耐磨性液体、泥浆或干料改进了密封性、延长了填料的使用寿命并减少了维护次数。它们的特点在于 DeZURIK 独有的高级填料系统，该系统由一个经过机械精加工达到紧密公差的圆弧形填料腔、以匹配圆弧形设计的闸板边缘、防推出密封环和多种材质可选的填料组成。全通径刀闸阀的特性为防腐蚀铸造不锈钢阀体、闸板、阀杆和填料压盖。一体化铸造成型的导向装置及卡簧保证阀门能长期运行。弹性阀座实现单向水密性零泄漏关断；金属阀座符合 MSS-SP81 标准。KGC 阀门可承受全反向额定压力。V 型孔设计可用于节流控制。DeZURIK 2-24 英寸 KGC 刀闸阀的设计及生产测试符合美国水行业协会(AWWA) C520 的要求。
Extended Service Cast Stainless Steel Knife Gate Valves are designed to meet MSS-SP81 and provide improved sealing, extended packing life and reduced mainte- nance in the toughest corrosive, abrasive liquid, slurry or dry material applications. They feature the DeZURIK Exclusive Premium Packing System consisting of a rounded packing chamber machined to tight tolerance, a matching knife gate with rounded edges, Anti-Extrusion Ring and many packing material options. The full port knife gate valve features a corrosion- resistant cast stainless steel body, gate, stem and packing gland. Cast-in guides and jams ensure long-lasting operation. Resilient seats provide unidirectional driptight shutoff; metal seats meet MSS-SP81 standard. KGC Valves can withstand full reverse pressure. A V-orifice design is available for throttling applications. DeZURIK 2-24" KGC Knife Gate Valves conform to the requirements for design and production testing of A W A C520.
