LM8580 碟片式套筒导向高压控制阀（平衡环密封）-上海深荣阀门有限公司手机版

产品简介

简要描述：LM8580 碟片式套筒导向高压控制阀（平衡环密封）是一种套筒导向，压力平衡式高压单座控制阀。采用新型迷宫碟片式套筒结构，高性能平衡密封环密封。多级降压、降噪，允许压差大、抗气蚀、降噪能力强等特点。适宜压差大、噪音强、气蚀严重等恶劣工况下的流体控制。

详细介绍

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.
