或者在较压力下逆时针旋转压力调节手柄。 

油温在-15 / + 70°C（5 - 158°F）之间。

使用满足上述给出的TJ粘度和油温的液压油

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

Note: For use with hydraulic fluids other than those listed above,  

Recommended Viscosity and Oil Temperatures

必须小心，以保持控制液压油的污染，

否则可能会导致故障并缩短阀门的使用寿命。

请保持NAS 1638-Grade 12内的污染程度。

 which may otherwise lead to breakdowns and shorten the life of the valves. 

 Please maintain the degree of contamination within NAS 1638-Grade 12.  

当蓄能器压力下降到压力切断时

阀门将泵输送到蓄能器和液压系统。

 一体式止回阀防止从蓄能器反向流过阀门。

在高压泵回路中，在小容量泵的负载运行期间，

阀以与上述相同的方式卸载大容量泵。

These valves are used to operate the pumps with minimum load in accumulator c ircuits or in high-low pump circuits.

  In accumulator circuits, when the system pressure reaches to a cut out pressure (adjusted maximum), 

the valve acts to divert the pump delivery to the reservoir a t low pressure, 

调整后，请勿忘记拧紧锁紧螺母。

当不使用子板时，安装表面应具有良好的加工精加工。

TJ的粘度和油温2粘度范围在15 - 400 mm / s（77 - 1800 SSU）之间。

Use 25 µm or finer line filter.  Control of Contamination

To adjust the pressure, loosen the lock nut and turn the pressure adjustment handle slowly clockwise for higher p ressures 

这些阀门用于在蓄电池电路或高压泵电路中以小负载运行泵。 

将蓄能器回路中的阀门和蓄能器之间的压降限制在切断压力的10％以下。

将排水口背压限制在切断压力的2％以下。

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

An integral check valve prevents reverse flow through the valve from the accumulator.  

In high-low pump circuits, the valve acts to unload the large volume pump with the same manner

 as described above during load operation of the small volume pump.

可以使用下表中列出的任何类型的液压油。

注意：使用上述以外的液压油时，TJ的粘度和油温

子板可用。从上表中子板型号。

When the accumulator pressure drops to the cut in pressure ， 

the valve directs the pump delivery to the accumulator and hydraulic system.

说明小心不要忽视将排水管连接到油箱;

在蓄能器回路中，当系统压力达到切断压力（调节较大值）时，

阀作用是将泵的输送转移到储存器的压，从而自动卸载泵。

or anti-clockwise for lower pressures.  After adjustments, do not forget to tighten the lock nut. 

Instructions Take care not to neglect connecting the drain pipe to the tank; 

otherwise not only will the valve fail to operate p roperly but also the line pressure will rise infinitely.  

Extend the end of the drain pipe into fluid. Limit the pressure drop 

between the valve and the accumulator in an accumulator circuit below 10% of the cut-out pressure.

Limit the drain port back pressure below 2% of the cut-out pressure. 

使用25μm或更细的线路滤波器。控制污染

要调节压力，请松开锁紧螺母，

并顺时针转动压力调节手柄，以获得更高的压力，

否则不仅阀门不能有效地操作，而且管路压力也将无限升高。

thus the pump is unloaded automatically.  

将排水管的末端延伸到流体中。
