2 Sub-plate model code The sub-plate is not provided with the valve. Order it separately if required by specifying the model code given in the table below. Model code J-M J-M J-M J-M Nominal diameter ⅜ ¾ Connection port diameter Rc⅜ Rc½ Rc¾ Rc1 Mass kg Refer to Page S- for the dimensions of the sub-plate. Handling low cannot be utilized with the solenoid either energized or demagnetized. low rate adjusting method (with T energized) Turning the flow rate adjusting screw counterclockwise increases the flow rate. Since a large force will be required to operate the flow rate adjusting screw when the pressures at ports and increase, adjust the flow rate at MPa { kgf/cm } maximum. The flow rate will not be zero even when the flow rate adjusting screw is fully tightened. See the minimum control flow rate characteristics. djusting response at switching djustment using the fixed throttles The response can be adjusted by changing the responsive adjusting fixed throttles (NPT 1 /1). t shipment, the product is not equipped with fixed throttles. If you require fixed throttles, order them separately by referring to the model codes below. Model code: T1-1- ( : Throttle diameter code) Tightening torque: to 7.5 N m { to 75 kgf cm} Throttle diameter code ixed throttle diameter φ. φ.7 φ. φ.9 φ1 φ1. φ1. φ1. φ1. φ φ.5 djustment using the pilot throttle valve To control the opening speed and closing speed of the valve separately, stack size stack valves below the solenoid pilot valve. When using stack valves, order mounting bolts separately by referring to the table below since the mounting bolts required differ depending on the stacking height. Opening speed adjustment Closing speed adjustment Opening/closing speed adjustment Stack valve model code MT--55 MT-i-55 MT--55, MT-i-55 Hexagon socket head cap bolt M5 9 M5 13 Quantity Tightening torque N m {kgf cm} to { to } Shocks at switching can be suppressed by using the shockless cartridge valve type (option code: K). -
