进口超高压针型阀，截止阀性能参数 Performance parameter
超高压针型阀间歇式填料系统设计，有效地减少填料的冷流及阀门的操作力矩，金属对金属的密封实现了理想的关闭，抗磨性和耐腐蚀性，提高了阀杆和阀座的使用寿命及重复开关循环次数 RETZ The intermittent packing system design of the ultra-high pressure needle valve effectively reduces the cold flow of the packing and the operating torque of the valve. The metal to metal seal achieves ideal closing, abrasion resistance and corrosion resistance, and improves the service life of the valve stem and valve seat and the number of repeated switching cycles
功 能：截断和节流、分流、合流 Functions: cut off and throttle, split flow, confluence
流动结构：直通式，直角式，三通式 Flow structure: straight through, right angle, three-way
特征：锥面、球面密封,活动阀瓣 Conical, spherical seal, movable valve disc

金属对金属阀座密封：实现气密性关闭，在磨蚀性流体应用中延长阀杆/阀座寿命，能够承受反复开关操作，且抗腐蚀性极佳。
Metal To Metal Seating：Implement tight closure, in abrasive.fluid applications extend the service life of the valve stem/seat, able to withstand repeated switch operation, and excellent corrosion resistance.
PTFE材质填料：确保阀杆与阀体间的密封。阀杆衬套和填料压盖材质可延长螺纹寿命，减小阀门操作扭矩。Ptfe Packing Material：Ensure that the valve stem and seal between the valve body. Stem bushing and lifting capping material can extend the life of the screw thread, reducing valve operating torque.
V型和调节型阀杆 V-type and regulating valve stem
填料位于阀杆螺纹下方，填料压盖锁紧装置可靠 The packing is located below the valve rod thread, and the packing gland locking device is reliable
