By exciting the solenoid,it switches the flow to port B.Contact us in advance if you use the pump with adouble-acting cylinder.By using the 4-way 3-position spool-type solenoidoperated directional valve, the pump operates adouble-acting cylinder. The hydraulic oil returnsfrom the pump to the oil tank at the center position.By using the pilot controlled check valve, thepressure can be maintained.If a high-capacity cylinder is used, it isrecommended to provide a pressure reducingcircuit.(For details on xx(x)-PA models, see 77 page.)75
