The integral filter prevents clogging of the bypass arrangement. The diaphragm is used in a flush valve diaphragm assembly and a flush valve.

Abstract: A pneumatic valve with lockout for controlling the flow of a fluid includes a housing, a fluid flow passage extending through the housing between a fluid inlet and a fluid outlet, and a valve movable along an axis to open and close the flow passage. A pneumatic actuator is operable to move the valve to open and close the flow passage. A manual lockout device is actuable to selectively enable and disable the valve. The device includes a locking member movable to prevent actuation of the lockout device when the valve is disabled. A fitting on the housing to convey a pressurized gas to the pneumatic actuator is mounted to swivel about the housing for connection to an air source on any radial within 360°. The valve is compact, simple to connect in a system and safe.

Abstract: A fluid control valve includes flexible coupling between a handle and a valve stem which allows the components of the assembly on one side of a wall to be angularly misaligned with the components on the opposing side. Because the components adjacent to the room side of the wall can be mounted perpendicular to the wall, a decorative escutcheon can be mounted flush against the mounting wall when the wall or the valve is out of plumb.

Abstract: An automatic flush actuation apparatus, which is incorporated with a flushing system having a water inlet, a water outlet, and a water chamber communicating therebetween, that includes a valve member being moved by a flush lever for releasing the water pressure within the water chamber to allow the water passing from the water inlet to the water outlet, and a sensor-operated powering assembly including a relief valve provided at the valve member for controlling the water flowing to the water outlet and an actuator arranged in such a manner that while sensing a presence of a user of the flushing system, the actuator is driven to move the relief valve to an opened position for releasing the water pressure within the water chamber to allow the water passing to said water outlet.

Abstract: A liquid flow control device includes an annular housing having an inlet for liquid in one periphery of the housing and an outlet for liquid in the other periphery. An annular block of water swellable material is located in the housing. A layer of sealing material encircles the annular block on the side thereof adjacent the inlet to close the inlet when the block is swollen through contact with the liquid.

Abstract: Methods of fabricating micro-valves and micro-pumps. The micro-valves and micro-pumps that are fabricated include electrically conductive diaphragms fabricated from electrically conductive nano-fibers. Fluid flow through the micro-valves and pumping action of the micro-pumps is accomplished by applying electrostatic forces to the electrically conductive diaphragms.

Abstract: A cover assembly for a lift station is disclosed. The cover assembly includes a cover in which an access opening, a cable passageway and a vent are defined. The cable passageway has one end that connects to the access opening and another end that opens to an exterior of the lift station. The cable passageway and the access opening are covered by hatches that can be opened to fully uncover the cable passageway and a portion of the access opening adjacent the cable passageway. This facilitates installation and maintenance of cables running between external equipment and internal equipment. The hatch covering the cable passageway is substantially solid to prevent venting of flammable gases. An interior of the cable passageway has an additional barrier to these gases. The vent is spaced apart from the cable passageway to further separate the cable passageway and external equipment from flammable gases.

Abstract: A hose control system comprising a receiver and a transmitter by which one can remotely control both the flow of water through a hose and the winding or unwinding of the hose onto a reel. The system preferably has power saving advantages, for example, by the use of a power control unit that reduces the power consumed by the electronics of the devices, but does not unreasonably disrupt the use of the devices. The receiver may be used with different aspects or all of the hose control system.

Abstract: A contained pipeline and leak detection system includes a primary pipeline section surrounded by a secondary pipeline section and an interstitial space formed between the primary pipeline section and the secondary pipeline section. A pressurized fluid reservoir having a volume of fluid, and in fluid communication with the interstitial space is provided. The fluid in the interstitial space has a pressure greater than the pressure of a fluid inside the primary pipeline section. A sensor detects changes in the volume of fluid in the fluid reservoir, which are indicative of leakage or system malfunction.

Abstract: A vacuum valve comprises a conical sealing surface arranged at a valve body, a valve disk at which a conical sealing surface is arranged, and a sealing ring having a first sealing surface and a second sealing surface. The valve disk, the valve body and the sealing ring are made of metal at least in the areas of the sealing surfaces. The valve disk is constructed so as to be curved or angled considered in axial section through the center and encloses an angle of less than 90° with the closing direction in the unloaded state at least in a radial outer portion adjoining the sealing surface. The valve disk has an elasticity such that a displacement of the radial outer edge of the valve disk relative to a point in the center of the valve disk of at least 0.1% of the diameter of the valve disk in direction of the center axis of the valve disk is bought about in the closed position of the valve disk relative to the open position of the valve disk by an elastic deformation of the valve disk.

Abstract: A flush actuator assembly is adapted to fit existing valve bodies. The flush actuator assembly includes a plunger rod which is capable of displacing the relief valve post more or less to adjust the flow of water through the flush valve during a single flush. The relief valve post may be displaced different amounts by adjusting the actuator assembly such that the plunger rod contacts the relief valve post at different locations along the central longitudinal axis of the post. Additionally, the relief valve post may be displaced different amounts by providing a plunger rod that has a different range of travel. A method associated with displacing the relief valve post varying amounts is also disclosed.
