LM8580 碟片式套筒导向高压控制阀（平衡环密封）
产品简介
详细信息
LM85/87系列套筒导向高压控制阀是一种套筒导向压力平衡式高 压单座控制 阀。采用分离式套筒结构，高性能金属密封环密封。具 有在高温高压下动态稳定性好,控制精度高,允许压差大，操作力 小，流通能力大等特点，适用于苛刻工况下的流体控制。
LM85/87 series cage guided high pressure balanced control valves are characterized by super dynamic stability, large allowable on-off pressure differential and smaller thrust force. All using three-piece separated cage combined optional spring-energized seal type or piston seal type take on excellent control precision and higher seat leakage rate. The temperature range varies with the sealing of different structures. They are best suitable to large pressure drop ratio, wide temperature change and high pressure conditions.
