LM85/87系列套筒導向高壓控制閥是一種套筒導向壓力平衡式高 壓單座控制 閥。采用分離式套筒結構,高性能金屬密封環密封。具 有在高溫高壓下動態穩定性好,控制精度高,允許壓差大,操作力 小,流通能力大等特點,適用于苛刻工況下的流體控制。
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.
