YUKEN单向减压阀，yuken减压阀部分资料

使用底板时，请按上述型号订货，不使用底板时，阀安装面精度，平面度0.013毫米，粗糙度0.0016毫米。

底板与H型压力阀通用，安装本阀时，底板要旋转180°〔上下相反〕使用。

安装时，务必对好阀的定位销与底板定位孔

调整压力时，松开锁紧螺母，缓慢转动压力调整螺钉，顺时针方向压力升高，逆时针方向压力降。

调定后，拧紧锁紧螺母。请把泄油口直接接入油箱。

管式连接式的1次侧有2个压力油口，可以把任意口作为入口，另一口与进油管路连接或堵住使用。

These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate

through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is depressed,

the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their principal

use is to control the speed of actuators in machine tools and similar applications.

减压阀是支回路，用来设定于主回路压力，同时还能够通过远程控制口，进行远程控制。

单向减压阀是减压阀并联单向阀，使之起到单向减压的作用。

Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.

Fluid Types

Any type of hydraulic fluids listed in the table below can be used.

Control of Contamination

Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may

otherwise lead to breakdowns and shorten the life of the valves. Please maintain the degree of contamination

within NAS 1638-Grade 12. Use 25 mm or finer line filter.

Recommended Viscosity and Oil Temperatures

Viscosity ranging between 15 - 400 mm2 /s (77 to 1800 SSU).

Oil temperatures between -15/+70°C (5 - 158°F).
