1 4-port valve Overview The / series manual selector valves are 4-port valves with a sliding valve method for the main valve. Suitable for operating cylinders of φ0 to φ0. Features Simple ease of operation with lower sliding Operation with a sliding lever (detent embedded rotary) method types are available according to applications : Miniature (Rc/4) : Standard (Rc/4, 3/8, /, 3/4) / Manual selector valve CONTENTS Series variation 70 Manual selector valve / Miniature () 708 Standard () 708 Safety precautions 7 M MN M MN W G MV *0EX *0E Always read the safety precautions in the Introduction and on page 7 before use. 705

7 Pneumatic components Safety Precautions Be sure to read this section before use. Refer to Intro Page 59 for general precautions for using valves. Product-specific cautions: Manual selector valve / Series CAUTION In locations with a lot of dust, prevent entry of dust by attaching a silencer to the port or through a similar method. The flow of air when switching is expressed by the letters indicated by the arrows on the tip of the switching handle. When : CYL, CYL When : CYL, CYL When N: all ports closed or CYL/ (ABR) connection N CYL CYL Switching different pressures (switching types of pressures) is enabled by configuring the higher pressure on the side and the lower pressure on the side. () If the higher pressure is not constantly applied on the side, this may lead to defective switching or air leakage. () Use a regulator with relief on the side. 90 Design/selection Mounting, installation and adjustment The main valve is a slide valve structure and there is internal leakage. The cylinder stopping position may change or pressure drop may occur due to internal leakage. For use with a -position valve, a 3-position all ports closed can be substituted. (N: Consider the neutral position as the transition period of the operation between.) When switching the handle position between N or N, there are positions that instantaneously connect to all ports. The manual operating force for the first operation after not being in operation for a while will be greater. M MN M MN W G MV CAUTION Be sure to install the piping for the air supply from. With the vertical piping specifications, a hex socket plug will protrude in order to mask the thread for lateral piping. Refer to the dimensions for detailed dimensions. For use with a panel mount, use a metric threaded component (*...4-M5, *...4-M). Refer to the dimensions for details. In consideration of panel mount installation, the handle assembly is shipped as an attachment. *0EX *0E 7
