1、高压、大流量 

较高工作压力：提高了约10%（31.5→35Mpa） 

油箱允许背压：提高了约30%（16→21Mpa） 

较大流量：提高了约60%（63→100L/min） 

2、压降 

与yuken公司老产品相比，压降值下降10%，因此装置更有效地节能。 

3、小型、紧凑 

即实现了高压、大流量、压降，又实现了小型、紧凑化。 

These are rectifier and surge absorber incorporated direct current solenoids which can be used by connecting directly

to the AC power source. They have, like other DC solenoids, such advantages that the sound in on-off operation is

quite low and the coils are hardly burnt out even if the spool is stuck at the half way of its changeover for contaminant

parti-cles etc. Moreover, they can be used almost permanently without being affected by a surge voltage from the outside.

Thus, they are the solenoids of high reliability and durability.

带有两个直流电磁铁型的阀，全长有210→205mm、重量2.2→1.85kg。 

4、具备有无冲击型 

除了高压、大流量的通用型而外，还有减小阀芯换向引起的噪声和管道振动的无冲击型。 

5、动作稳定 

采用高吸力电磁铁和弹簧，了污染工况下仍有良好的动作稳定性。 

6、符合IP65标准的高防尘、放水性 

符合I.E.C.Pub.529.IP65.JIS C 0920 Ip65（防尘、防喷流型）标准，具有优越的防尘、放水性。 

DC Solenoids (Reputable K-Series)

These DC solenoids have surge absorbers for K-series functions. The three advantages of them are as mentioned

below:-

Since surge voltage can be controlled to a very low figure, electric control devices, such as a computer, can be used

without any interference like noise.

There being no spark between contacts, the life of the relay becomes longer.

Time lag for spool return after de-energisation of the solenoid is very short.
