For use in combination with a system for separating water from pressurized fuel in a filter-separator tank, there is provided a float valve and weight device that prevents fuel from leaving the tank if the interface between fuel and water is at an undesirably high elevation. The float of the float valve is associated with a weight, the relationships being such that the float floats at the interface. To test the float for waterlogging, and to test the entire system, the association between float and weight is discontinued. The float then floats up unless waterlogging has occured.

A manual control valve for a remotely operated munitions magazine sprinkler valve employs a compact body, a pressure input port and first and second output ports to which are secured tubular seat housings, each carrying a valve seat. First and second poppets are slidably mounted in the tubular seat housings and are spring urged to closed position. One or the other of the poppets is pulled open by means of a handle operated rotary cam, which allows both poppets to be closed by spring and water pressure. A modified valve configuration provides a three-way valve.

Manual control valve

A turbine generator system for use in a flow line from a water supply to a water usage, treatment or storage system employs a remotely controlled valve for control of the flow of water through the turbine. The system is arranged to shut down upon occurrence of under or over voltage at the generator or loss of pressure at the turbine, disconnecting the generator from the utility line and closing the control valve to stop flow through the turbine. Should failure of the utility line power decrease the generator load to increase turbine speed, restart is prevented until the control valve has closed to stop the turbine. A time delay in the control panel shuts down the system if the control valve does not open within a selected time interval after start up. To accomodate daily variation of flow rate to a water distribution and usage system, a first turbine generator and control valve have a capacity to handle a minimum flow rate and a second turbine generator and control valve, in parallel with the first, automatically come into operation when the flow rate exceeds the capacity of the first turbine generator and control valve.

A diaphragm valve includes an apertured diaphragm plate that separates mutually concentric input and output valve chambers. A flexible diaphragm extends somewhat loosely across the plate and seals an operating chamber on one side of the plate. The chamber contains a spring pressed retainer plate having a sealing lip bearing against, but otherwise unsecured to, the diaphragm so that by controlling pressure within the operating chamber, the primary sealing closure is broken and the retainer plate apertures may be progressively blocked or unblocked as the diaphragm moves to and from the diaphragm plate apertures.

A high capacity direct acting three-way bistable power operated valve is connected to control operation of an hydraulically operated magazine sprinkler control valve. The three-way bistable valve controls application of high pressure sea water and includes a slidable hollow valve spool having one end that is selectively seated upon and sealed against a valve seat in an inlet chamber, and having an intermediate spool portion connected to a common valve port. The other end of the hollow spool extends into an outlet chamber and is sealed against a valve seat therein when the first end of the spool is displaced from its valve seat and vice versa. Input pressure on the spool can be completely balanced or arranged to enhance sealing of the spool. The valve spool is axially shifted and latched either by a motor operated cam circuit arrangement or by driving and unlatching solenoids.

Hollow spool valve

A fluid operated pinch valve comprises a flexible sleeve fixed at its ends within a valve casing that has a laterally facing opening through which the sleeve may be inserted and replaced without removing the valve casing from the flow line. A casing cover section has a planar sealing face that bridges the opening for sealing engagement with the main casing section, and which also seals against linear sealing flanges on ends of the flexible sleeve.

A safety control system for a pump and anti-surge valve protects the pump, the valve and the hydraulic main line system. The valve is controlled by a pressure responsive circuit and, via a limit switch on the valve, controls both the steady state running of the pump and the pump start. A timed start circuit allows pressure to build up sufficiently to operate the valve upon initiation of pump operation. The system automatically shuts down upon power, mechanical or hydraulic failure, and prevents continued operation of the pump control valve when the pump has lost suction or there is a decrease in pump discharge pressure.
