A valve part, a discharge valve part that opens and closes between an output port and a discharge port, and a drive part that switches between them are provided, and the drive part is driven by fluid pressure of the output port supplied through a pilot valve. When the fluid pressure at the output port is high, there is a drive part for the supply valve part that communicates the supply port and output port in a fully open state, and a drive part for the supply valve part that communicates with the supply port in a fully open state when the fluid pressure at the output port is high. A slow start control valve comprising: a drive section for a discharge valve section which opens against a biasing force and also presses the supply valve section when fully opened to communicate with the supply valve section in a slightly open state; .
