Handling Pilot With the internal drain type, maintain the pressure difference etween the pilot pressure and the ack pressure of the tank line no lower than the minimum pilot pressure of.45 MPa {4.5 kgf/cm 2 }. When using the product with spool type 3, 33, 5, or as the internal pilot type, insert a resistance valve with a cracking pressure of.45 MPa {4.5 kgf/cm 2 } minimum in the tank line and set it as the external drain type. Drainage Directly connect the drain piping to the tank without merging it with other tank piping. External pilot type products can e used as internal drain type regardless of the model. Internal pilot type products can e used as internal drain type when the spool type is 2, 4, 44, 7, 8, 9 or 27. Pilot throttle valve To suppress shocks at switching y adjusting the switching speed of the spool, stack one of the following 2 size stack valves elow the solenoid pilot valve. When using stack valves, order mounting olts separately y referring to the tale elow since the required mounting olts vary depending on the stacking height.
