簡要描述：LM8580 碟片式套筒導向高壓控制閥（平衡環(huán)密封）是一種套筒導向，壓力平衡式高壓單座控制閥。采用新型迷宮碟片式套筒結(jié)構(gòu)，高性能平衡密封環(huán)密封。多級降壓、降噪，允許壓差大、抗氣蝕、降噪能力強等特點。適宜壓差大、噪音強、氣蝕嚴重等惡劣工況下的流體控制。

詳細介紹

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(jié)構(gòu)，高性能金屬密封環(huán)密封。具有在高溫高壓下動態(tài)穩(wěn)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.
