A gas distribution system, a reactor system including the gas distribution system, and method of using the gas distribution system and reactor system are disclosed. The gas distribution system can be used in gas-phase reactor systems to independently fine tune gas source locations and gas flow rates of reactants to a reaction chamber of the reactor systems.

A fluid pressure control device includes a first circuit system having a first pump and a first control valve. The first circuit system includes an intermediate cut valve provided downstream of the first control valve in a first intermediate passage and which connects and disconnects a connection between the first intermediate passage and the tank, and an external output port communicating at a part downstream of the first control valve in the first intermediate passage and upstream of the intermediate cut valve, the external output port being capable of externally supplying working fluid discharged from the first pump.

To provide a portable device capable of capturing a flow of water from a stream, storm drain or runoff channel, on command and send that captured water into a pipe system, while allowing remote adjustment of the capture and flow rates out of the cube device, the stormwater syphon cube includes a rock grate to prevent stormwater borne objects from entering the device, and an exit valve adjustable via cable control, a side extraction valve adjustable via cable control to adjust the water flow into the extraction pipe, and extraction pipe attached to the cube to carry extracted water away to storage. The sealed exit pipe acts as a syphon drawing water out of the cube.

A three-way valve includes an inflow port, a body having therein a valve chamber introducing fluid from an inflow passage of the inflow port; a first outflow port having an outflow passage extending at an acute angle to a reference direction in which the inflow passage extends; a second outflow port having an outflow passage extending from the valve chamber at an acute angle to the reference direction; and a valve element disposed inside the valve chamber and movable to adjust flow rates of the fluid in the first outflow port and the second outflow port. At least one of the first outflow port and the second outflow port includes a bent portion connecting the outflow passage and a downstream passage such that the downstream passage becomes closer to the reference direction than an extending direction of the outflow passage to the reference direction.

A valve assembly includes a valve body, having an inlet duct, an outlet duct and an intermediate portion. An electrovalve is located proximal to the intermediate portion. A measurement device is directly connected to the valve body. The measurement device includes a sensor for taking a measurement for determining a physical characteristic of the fluid that can flow in the valve assembly. The electrovalve includes a first electronic circuit for conducting an electric control signal from a control unit to the electrovalve. The measurement device includes a second electronic circuit for conducting the electric signals exchanged between the control unit and the sensor. The first electronic circuit and the second electronic circuit are implemented on a single header or printed circuit board. The electrovalve and the measurement device are mechanically connected directly to the single header or printed circuit board.

Apparatus and associated methods relate to a pneumatic distribution system having pneumatic pump that exhausts into a common plenum that is in fluid communication with a plurality of flow controllers. In an illustrative embodiment, a system controller may coordinate the operation of the one or more pneumatic pumps and the plurality of flow controllers to provide air pressure control to a system of pneumatic chambers. In some embodiments, one of the plurality of flow controllers may be configured to provide fluid communication with an ambient atmosphere so as to permit a fluid path from a pneumatic chamber connected to another flow controller to the ambient atmosphere via both flow controllers and the common plenum. In an exemplary embodiment, the system controller may advantageously control the air pressures in a plurality of pneumatic chambers independently of one another using coordinated control of the pump and flow controllers.

A water heating system having a system inlet pipe (1.002), a hot water delivery pipe (1.003) and a hot water return pipe (1.006) connected to a building hot water distribution network (1.024); the water heating system including one or more water heaters (1.001), the or each water heater having a heater inlet (1.022) and a heater outlet (1.023), a hot water return pipe (1.006) connected between the system inlet and delivery outlet via the building hot water distribution network to form a close loop hot water supply-return circuit; a pump (1.005) connected to circulate water through the hot water supply-return circuit whereby the pump can circulate water through one or more of the water heaters; a valve means (1.007) a first non-return valve adapted to prevent inlet water (water delivered to the system inlet) from flowing into the hot water return pipe or the building hot water distribution network.

In one representative example, a water delivery apparatus includes a chassis and a water system supported on the chassis. The water system is substantially lead-free and adapted for use with potable water. The system includes a manifold adapted to convey and/or contain water in a substantially leak- proof manner. The manifold extends between an intake connection and a distal terminus valve. The system also includes first, second and third outlet legs and a pump adapted to induce water flow within the manifold principally from the intake connection to one or more of the outlet legs. The system also includes a pressure switch, an accumulator tank and a cycle to stop valve, all of which are operatively connected to the manifold.

A valve block for single use in a bioprocess, having a plurality of valve units and a one-piece block body having a main conduit. Each valve unit includes a secondary conduit, a valve seat between the secondary conduit and the main conduit, a closure part having a gripping portion, and an actuator coupled to the gripping portion which can transfer the closure part from a first switching position, in which the closure part is pressed against the valve seat and blocks a fluid communication between the secondary conduit and the main conduit, to a second switching position, in which the closure part is lifted from the valve seat and unblocks the fluid communication between the secondary conduit and the main conduit. The gripping portion is sealed against both the main conduit and the secondary conduit in both switching positions of the valve unit.
