Keystone K-LOK Series 36/37 High Performance Butterfly Valve
Keystone K-LOK系列36/37高性能蝶阀
The Keysotne K-LOK Series 36/37 is a high performance butterfly valve rated to ASME Class 150 and 300, available in wafer, lugged and flanged style.The unique design does not rely on pressure to assist sealing and therefore seals at high and low pressures, as well as dirty services.
基士敦/凯思通/凯斯通K-LOK系列36/37是一个高性能蝶阀额定为ASME级150和300，有对夹式，凸耳式。独特的设计不依赖压力来辅助密封，因此在高和低压力下密封，以及肮脏的服务。
Features
· K-LOK polymer and elastomer seats provide bi-directional, drop-tight shut-off in vacuum as well as at full rated differential pressure.Its unique design does not rely on pressure to assist sealing therefore seals at high and low pressures, as well as dirty services.A variety of materials allows optimum seat life in all applications.
· Blow-out resistant shaft is standard on all valves for increased safety.
· Unique packing design allows for use in pressure as well as vacuum without modification or special assembly.
· Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure.
· Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks.
· Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
· Extended neck allows for 50 mm (2") of pipeline insulation.
· Integrally cast mounting pad provides direct mounting of actuators eliminating the need for costly brackets and couplings.
· Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.
Keystone K-LOK系列36/37高性能蝶阀
- K-LOK聚合物和弹性阀座提供双向密封，在真空以及在全额定压差.其独特的设计不依赖压力来辅助密封，因此，密封在高和低的压力，以及肮脏的服务。在所有应用中，各种材料都允许*佳的使用寿命。
- 所有阀门上的防爆轴都是标准的，以提高**性.
- 独特的包装设计允许在压力和真空中使用，无需修改或特殊装配。
- 阀板锥度销是切向定位的一半在阀瓣，一半在轴，放置在压缩而不是剪切，这消除了潜在的风险。
- 摇杆形压盖桥对压盖螺母的不均匀调整进行了补偿，减少了填料泄漏。
- 整体铸造阀瓣位置停止上乘定位阀瓣在阀座上，达到*大阀座和密封寿命。
- 扩展颈允许50毫米(2“)管道绝缘。
- 整体铸造安装座提供直接安装执行机构，直接取消了支架和转换轴，有效降低成本。
- 轴颈孔扁平阀体孔将轴轴承放置在阀瓣附近，提供*大的轴支撑，从而减少磨损，延长使用寿命。
