A nut means engages with a thread formed on an outside surface of the cylindrical form valve body. A valve member having a flow restricting means such as needle valve device on one end is fitted slidably within the valve body and the same is connected to the nut means with an engaging member which is slidably fitted within a slit formed lengthwise on said threaded surface and engages with the valve member and the nut means. Fluid flow in the valve body is regulated by moving said valve member by turning said nut means. Thus the flow regulating valve of very compact form and capable of making fine adjustment of the flow rate can be provided because the conventional valve stem which engages with the internal thread of the valve body and projecting out therefrom for regulating flow is not used, and the adjustment is made with the thread of comparatively large diameter. Such flow regulating valve can be used suitably for controlling piston speed of power cylinder by providing the check valve therein.
