Claims

[Scope of utility model registration request]

・' Two main valves each equipped with a main valve body are arranged in parallel on a valve body that has a supply port for supplying pressure fluid, a load port that connects to a fluid actuator, and a discharge port that connects to a low pressure side. Two pilot solenoid valves are provided to introduce pilot fluid into the pilot chamber of each main valve and release the pilot fluid in the pilot chamber to the low pressure side, and each main valve element of the two main valves is connected to the pilot chamber of the pilot chamber. Open the fluid to the low pressure side and shut off the supply port to load bow 1.
- and the discharge port are connected, pilot fluid is introduced into the pilot chamber, the supply port and the load port are connected, and the discharge port is shut off, and the pilot fluid is introduced when the two pilot solenoid valves are mismatched. A composite 3-port solenoid valve comprising a communication passage so that pilot fluid in a pilot chamber of one main valve is released to a low-pressure side via a pilot solenoid valve of the other main valve.
