Abstract: A portable disinfectant transfer system for transferring a toxic and/or noxious fluid between a container and a reprocessor reservoir includes a container for containing the fluid, a pump having a conduit for drawing the fluid from the reservoir and expelling the fluid through an opening of the conduit into the container and an opening in the container for receiving a neutralizing chemical into the container simultaneously with the expelling of the fluid from the reservoir into the container to provide a simultaneously introduced neutralizing chemical. The opening of the conduit is positioned to produce a swirling motion of the fluid within the container to mix the simultaneously introduced neutralizing chemical with the fluid while the fluid is expelled into the container. A further pump having a further conduit is provided for drawing the fluid out of the container.

Abstract: A pilot operated pressure valve which limits the rate of pressure rise and substantially eliminates excessive system and tank pressure spikes. Because the pilot ball downstream of the damping orifice is held off the pilot seat in the normal starting condition by a pilot return spring, the main piston will open immediately when system pressure overcomes the low bias pressure of the main spring. A pilot pressure bypass port, which selectively deactivates the pilot chamber features, may also be included.

Abstract: A fluid proportioning valve meters flow of pressurized inlet fluid in proportion to a pressure drop between the inlet and outlet of the valve. A pressure acutated, return biased poppet valve is actuated by the fluid above threshold fluid pressure to meter fluid to the outlet against spring force. The poppet is annular and has a circular metering edge that controls flow through circumferential orifices in a valve guide. Smooth stable flow is achieved by shearing action of the metering edge over the orifices. Sliding point contact with the poppet valve by non-ferrous convex buttons to eliminate galling and reduce particle contamination within the valve.

Abstract: The invention provides valves of the type employing a differential pressure regulator and a characterized valve with a mechanism to enhance control of fluid flow independently of system pressure. The valves of the invention are especially suitable for HVAC applications, and provide operation with improved accuracy over a greater flow range with a reduced risk of hunting. In one preferred aspect, the invention provides improvements by the employment in the differential pressure regulator of a diaphragm with a cup arranged to provide a small leakage, thereby dampening the response of the regulator. In another aspect, a baffle is provided to protect the downstream side of a control disk forming part of the differential pressure regulator.
