A pressure regulating valve includes a casing, a holder, a fixed valve, a movable valve, a spring member, a diaphragm, and a filter. The filter is configured to filter fluid flowing from a flow inlet of the casing into a pressure chamber. The filter includes a filtering part for filtering fluid and a holding part including a frame part for holding an outer periphery of the filtering part. An alignment structure configured to align the holding part at a predetermined position is provided between the holding part of the filter and the holder, or between the holding part of the filter and the casing.

A pressure control valve has a housing including a valve seat and defining a fluid path therein, a valve body including a support member and a valve member, and a spring biasing the valve body toward the valve seat in a valve closing direction. The valve member is an integrated molding including a seal member and a reinforcement member that reinforces the seal member. The seal member is made from a rubber-like elastic material and includes a seal portion that is configured to be seated on the valve seat. The reinforcement member is engaged with the support member without using a separate member such as adhesive.
