1 4 port valve Overview The and Series manual switching value is 4 port valves incorporating a sliding valve for the main valve. This value is suitable for driving cylinders ø0 to ø0. eatures Low sliding movement facilitates operation A swing lever (detent integrated rotary) is used for operation. Two types available based on application Miniature type (Rc/4) Standard type (Rc/4, /, /, /4) / O N T E N T S Series variation Safety precautions / Miniature type () 4 Standard type () 4 MNE0 M MN W 4L-4/ 4SA/B *0E QV Refer to the safety precautions on Introduction and page before starting use.

Refer to Intro for valve general precautions. / Series Design & Selection MNE0 M MN AUTION or the place subject to dust, please take countermeasures such as installing silencers at port to prevent dust intrusion. When switching the valve, the arrow on the top of handle shows the direction of air flow. or : YL, YL or : YL, YL or N: All ports closed or YL/ (A/B/R) connection YL When using -position type, the valve can be substituted by -position all ports closed type. (N: Neutral position during transition period of operation.) Main valve with sliding structure may cause internal leakage. This internal leakage may cause a change of cylinder stop position or pressure drop. When the handle position is switched between N or N, all ports may be connected for an instant. W 4L-4/ 4SA/B or switchover of multi-pressure (switching types of pressure), connect higher-pressure to side, while connect lower-pressure to side. () If higher-pressure is not always supplied to side, switchover defective and air leakage may be caused. () Please use a regulator with relief at side. AUTION YL The air should be supplied from port. Since vertical piping specifications provide masking of side porting thread, a hexagon socket head plug projects from the side wall. Please refer to dimensions for details. 90 Installation & Adjustment or panel mount, select meter thread (*...4- M, *...4-M). Please refer to dimensions for details. The handle assembly is enclosed with the product at delivery to enable panel mounting. *0E QV N
