或者在較壓力下逆時針旋轉壓力調節手柄。 

油溫在-15 / + 70°C（5 - 158°F）之間。

使用滿足上述給出的TJ粘度和油溫的液壓油

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

必須小心，以保持控制液壓油的污染，

否則可能會導致故障并縮短閥門的使用壽命。

請保持NAS 1638-Grade 12內的污染程度。

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

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

當蓄能器壓力下降到壓力切斷時

閥門將泵輸送到蓄能器和液壓系統。

 一體式止回閥防止從蓄能器反向流過閥門。

在高壓泵回路中，在小容量泵的負載運行期間，

閥以與上述相同的方式卸載大容量泵。

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, 

調整后，請勿忘記擰緊鎖緊螺母。

當不使用子板時，安裝表面應具有良好的加工精加工。

TJ的粘度和油溫2粘度范圍在15 - 400 mm / s（77 - 1800 SSU）之間。

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 

這些閥門用于在蓄電池電路或高壓泵電路中以小負載運行泵。 

將蓄能器回路中的閥門和蓄能器之間的壓降限制在切斷壓力的10％以下。

將排水口背壓限制在切斷壓力的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類型的液壓油。

注意：使用上述以外的液壓油時，TJ的粘度和油溫

子板可用。從上表中子板型號。

When the accumulator pressure drops to the cut in pressure ， 

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

說明小心不要忽視將排水管連接到油箱;

在蓄能器回路中，當系統壓力達到切斷壓力（調節較大值）時，

閥作用是將泵的輸送轉移到儲存器的壓，從而自動卸載泵。

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或更細的線路濾波器。控制污染

要調節壓力，請松開鎖緊螺母，

并順時針轉動壓力調節手柄，以獲得更高的壓力，

否則不僅閥門不能有效地操作，而且管路壓力也將無限升高。

thus the pump is unloaded automatically.  

將排水管的末端延伸到流體中。
