您要查找的是不是：
- Knife Gate valves should preferably not be opened or closed against pressure. 刀闸阀不适合顶着压力进行开启或关闭。
- Virtually no contamination of the environment. No dewatering of stock, unlike standard knife gate valves. 不会对环境造成实质的污染。与标准刀闸阀不同,不需要库存脱水。
- This operation can be done many times insuring that the Velan knife gate valve gives years of reliable service. 这种操作可以进行多次,以确保。
- Standard wafer, TAPPI face-to-face for easy replacement of leaky standard knife gate valves. 标准的对夹式，TAPPI（美国纸浆与造纸工业技术协会）面对面结构，替换泄漏的普通刀闸阀简便易行。
- Unlike any other design, the Bi-Directional Knife Gate Valve provides a combination face and perimeter seal. 与其它设计不同的是，双向刀闸阀结合了密封面与圆周密封的双重优点。
- Thicker knife gate to eliminate distortion under maximum differential pressure and to provide tight seating (see page 12 ). 更厚的刀闸能够避免在最大压差环境下产生的扭曲,保证阀座的气密性密封(参阅第12页)。
- Each silo has the potential to use six Type A Valves, one Series D Slurry Knife Gate and three Series 75 Manual Pinch Valves. 每个贮料筒仓一般需要六个A型夹管阀，一个系列D泥浆刀闸阀和三个系列75手动夹管阀。
- Beveled knife-stem connection locks the knife blade tight against the seat. The seat is sealed by positive torque closure - not media pressure - unlike any other knife gate valve. 斜面的闸刀-阀杆连接部将闸刀紧固地锁紧在阀座上。与其它刀闸阀不同的是,我们的阀座采用主动扭矩闭锁进行密封,而不是采用介质压力密封。
- Standard packing chamber with 125 RMS wall finish, burnished non-rotating stem and PTFE or graphite packing rings. Many times the cycle life of a standard knife gate valve. 使用寿命长的防泄漏阀杆密封。标准填料腔具有125 RMS壁面光洁度,光面的不旋转阀杆和聚四氟乙烯或石墨填料环。使用寿命是标准刀闸阀的许多倍。
- Due to unique torque closure of its'seat, the Velan Bolted Bonnet Knife Gate Valve is an ideal solution for low pressure, high cycling, environmentally sensitive services and bidirectional applications. 由于采用独特的阀座扭矩关闭,Velan螺栓阀帽刀闸阀特别适用于低压、开启关闭频繁、环保要求高、双向流动的应用环境。
- S.Navy.Velan Inc., pioneered many designs which became industry standards, including bellows seal valves, all stainless steel knife gate valves and forged valves up to 24" (600 mm). Velan在许多方面的创新已经成为行业标准，包括波纹管密封阀门，所有不锈钢刀闸阀和通径达DN600的锻造阀门。
