The invention has a purpose of obtaining a brake hydraulic pressure controller capable of securing durability with a simple configuration and a motorcycle brake system. The brake hydraulic pressure controller is a hydraulic pressure controller for a vehicle brake system and includes: a base body that is formed with a channel filled with a brake fluid therein; a hydraulic pressure regulation valve that has a plunger and opens/closes the channel by translatory movement of said plunger; a drive coil that has a hollow section, is vertically provided in the base body in a state where one end of the plunger is inserted in said hollow section, and causes the translatory movement of the plunger to drive the hydraulic pressure regulation valve; and a coil casing that accommodates the drive coil. The coil casing includes a wall that covers at least a part of an apex of the vertically-provided drive coil, and the drive coil is pressed toward the base body by a projection formed in the wall.

A fluid valve manifold has an electrical conduit for receiving a circuit board assembly that actuates a plurality of valve units. The circuit board assembly is reversibly and rotatably mountable to a first position or second position in the electrical conduit such that a respective set of first electrical connectors at a first end or a second set of electrical connectors at a second end opposite that of the first end may be in position to receive electrical signals through the respective connectors. When in one position, the circuit board assembly is able to serve a single solenoid valve unit. When in a rotated second position, the circuit board is able to serve a double solenoid valve unit.

A hydraulic fracturing tree wing is formed with a studded hydraulic valve next to a manual valve. The stud-to-flange connection allows for a shorter, lighter wing. The studded hydraulic valve maybe a gate valve that includes a T-slot coupling between an operating stem and the gate. A bonnet seal ridge may be formed to withstand undue deformation during operation that wears or destroys seals. A method for forming a hydraulic fracturing tree assembly includes using a flanged manual valve with a studded hydraulic valve. Other valves and methods are presented.
