徴とするパイロツト形電磁弁。 In a pilot type solenoid valve in which the spools in the main valve part are driven in opposite directions by the pressure of the pilot fluid caused by energization to the two pilot valve parts to switch the fluid flow path, the pilot valve part in the pilot valve part The exhaust passages are individually communicated with the exhaust ports of the main valve part through the passage holes formed in the main valve part, and each of the pilot exhaust passages is connected to a flow path that is smaller than the passage hole formed in the spool of the main valve part. A pilot type solenoid valve characterized by communicating with each other through through holes with low resistance.
