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 1. 3.9 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.
