An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

A flow path switching valve includes (a) a valve body in a shape of a rectangular parallelepiped having a predetermined surface and an opposite surface, the valve body including an open flow passage having an opening on the predetermined surface, (b) a main body including a plurality of ports having a respective opening on a facing surface thereof facing the predetermined surface, and a plurality of connection flow passages each connected to respective one of the plurality of ports, (c) a pair of plate springs attached to opposite ends of the valve body to support the valve body with a predetermined gap formed between the predetermined surface and the facing surface, the plate springs applying elastic force to the valve body in accordance with an amount of movement of the valve body in a predetermined direction, and (d) an actuator for reciprocating the valve body in the predetermined direction.

A three-way valve is disclosed. The valve achieved constant flow rate as the valve transitions from 100% flow through the first path to 100% flow through the second path. The valve is linearly actuated, which allows a plurality of valves to be efficiently disposed in a manifold. The valve comprises a spool having two passageways therethrough which converge at the input. The spool is disposed in a housing. By linear movement of the spool within the housing, the amount of the incoming flow that passes through each of the two passageways can be controlled. In certain embodiments, the spool is in communication with an actuator to control its position within the housing. The three-way valve may be used as part of a manifold.

Passage forming blocks of a first pilot valve and a second pilot valve each include a supply passage, which opens in a first surface and a second surface and is connected to a valve chamber, a first output passage, which opens in the first surface and are connected to the valve chamber, and a second output passage, which opens in the first surface. Further, the passage forming blocks each include an output passage connecting recess. The output passage connecting recess is provided in a section of the second surface that overlaps with an opening region of the first output passage, which opens in the first surface, and is connected to the second output passage. The first output passage of the first pilot valve is connected to the second output passage of the second pilot valve via the output passage connecting recess of the second pilot valve.
