A method of controlling the flow of different flow paths of fluid is provided. The method includes rotating a valve to a first position, receiving a first concentrate in the first position, discharging the first concentrate through one of two outlets, rotating the valve to a second position, receiving a second concentrate in the second position, and discharging the second concentrate through one of the two outlets.

An adjustable multiple bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member is disposed within the outer bladder and divides the outer bladder into two distinct inflation chambers. The inflation chambers may be inflated separately.

A rotary-type valve device includes: a tubular valve having an inner passage and opening parts opened in an outer circumferential wall from the inner passage toward an outward side in a radial direction; a housing accommodating the valve and turnably supports the valve; a tubular passage member assembled in the housing such that the passage member abuts on the outer circumferential wall of the valve and defining a radial-direction passage; and a biasing spring biasing the passage member toward the outer circumferential wall The passage member includes an abutting member abutting on the outer circumferential wall, and an intervening member having an annular pressing part intervening between the abutting member and the biasing spring and partially pressurizing the abutting member. The abutting member includes an annular sealing surface aligned with the annular pressing part in a biasing direction of the biasing spring.

A flow path switching valve is used in an engine water cooling system mounted on a mounting surface of an engine, and switches a flow path of a cooling water in the engine water cooling system. The engine water cooling system has a block jacket formed on a cylinder block and a head jacket formed on a cylinder head, connected to each other via a communication passage. The cooling water flowing in from an inlet of the block jacket flows into an inlet port of the flow path switching valve from an outlet of the head jacket via the communication passage. An inflow barrier plate is provided, which closes a part of a leak path side of the inlet port to suppress an inflow of the cooling water from the block jacket via a leak path made in the cylinder block and the cylinder head.

A three-way valve includes a sample port acting as a dual port, a sensor port and a purge port. The purge port selectively provides the sample port with a purge gas when an etching chamber is idle and the sensor port is not in use.

A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.
