弁。[Claims for Utility Model Registration] A slow start control valve comprising a main valve, an electromagnetically controlled pilot valve that drives the main valve, and a fluid pressure controlled pilot valve that is operated by the fluid pressure of the electromagnetically controlled pilot valve. , The main valve includes a supply valve section that opens and closes between the supply port and the output port, a discharge valve section that opens and closes between the output port and the discharge port, and a drive section that switches between them. The drive section includes a rod that passes through the supply valve section and the discharge valve section, and a piston attached to the tip of the rod, and when the piston is in the returned state due to the biasing force of the return spring, the supply valve body and the The supply fluid pressure acting behind the piston can hold the discharge valve in the closed state and at the same time keep the discharge valve in the fully open state. The valve part is communicated with a small opening, and when the fluid pressure of the output port increases accordingly, the piston is operated by the action of the fluid pressure, allowing both ports to communicate with each other at a full opening. Slow start solenoid valve.
