2 /0 Hengli hydrulic Hydrulic components Directionl vlve Type M-.SEW...LX Function nd configurtion M-SEW directionl vlve is solenoid shut-off directionl poppet vlve for control oil opening, stop nd flow direction. Two-position three-wy solenoid directionl poppet vlve min consists of vlve ody (), Solenoid (), nd vlve element (). Connect superposition plte elow the two-position three-wy solenoid directionl poppet vlve to connect vlve ody (), it ecomes into two-position four-wy direction poppet vlve. Mnul emergency utton (5) cn e used to operte the vlve when the solenoid is not powered on. M-SEW two-position TEE solenoid directionl poppet vlve ). Initil position: when the solenoid is not energized, pretention of spring (6) keeps vlve element () on vlve set (7) on the left, so tht oil port is connected to nd oil port T is closed. ). Switching position: fter the solenoid is energized, through ngulr lever (9) nd ll (), the force of Solenoid () cts on push rod () of the two-side sel, thus to push vlve element () nd mintin it on right vlve set (), cusing oil port closed nd oil port connected to port T. Since push rod () nd vlve element (), cted y the inlet pressure, is in lnce stte of xil hydrulic pressure, therefore, the vlve cn e used when pressure is up to 0r T T B M-SEW two-position TEE solenoid directionl poppet vlve M-SEW -position -wy solenoid directionl poppet vlve M-SEW -position -wy solenoid directionl poppet vlve ). Initil position: when the Solenoid is not energized, pretention of spring (6) keeps vlve element () on vlve set () on the right, oil port is closed nd port connected to T; pressure oil supplied from oil port push steel ll () to vlve set (), upon which oil port is connected to B nd connected to T; control oil line is connected from oil port cts on the lrger re of control piston (), which cn e used for unloding to oil tnk. ). Switching position: fter the Solenoid is energized, oil port is connected to ; pressure oil from the pump goes through the control oil line connected from port nd cts on the lrger re of control piston (); steel ll () is pushed to the other side of vlve set (), thus oil port is connected to nd B connected to T. Crtridge restriction choke (model M-.SEW.LX/../B...) To restrict flow through the vlve, restriction choke cn e instlled. Restriction choke is instlled on port. Crtridge type one-wy vlve (model M-.SEW.LX/../) Crtridge type one-wy vlve llows oil flow in from port nd it is closed for reverse flowing. One-wy vlve instlled on port.
