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
