Abstract: A two-stage regulator having a piston situated in a first stage for substantially reducing high pressures introduced into the regulator. The reduced pressure is exerted against the second stage that includes a plunger-actuated diaphragm that urges an actuator to open a ball valve at a selected pressure to allow fluid to flow out of the regulator at a desired reduced pressure.

Abstract: Two-stage and three-stage regulators having a piston situated in a first stage for substantially reducing high pressures introduced into the regulator. The reduced pressure from the first stage is exerted against a second-stage valve in a two-stage embodiment, and against an additional third-stage valve in a three-stage embodiment, each valve of which includes a plunger-actuated diaphragm that urges an actuator to open a ball valve at a selected pressure to allow fluid to flow out of the regulator at a desired and much-reduced pressure.

Abstract: Stem-actuated two-way valve for precise, intermittent and repeatable delivery of fluid and/or gaseous substances from high pressure sources. A dual purpose o-ring functions as a valve seat and separates high pressure segments from low pressure segments. The novel valve stem system allows precise delivery of desired liquids and/or gases regardless of valve stem travel within a defined travel length.

Abstract: A multi-port valve is disclosed having a ball bearing support system for a stator/rotor/valve stem assembly within a valve housing. Slipper seals or alternatively, poppet seals, connect a plurality of apertures situated in the rotor and a plurality of apertures situated in the adjoining stator so that a common central fluid receiving channel of the stator can be connected to a peripheral fluid delivery channel of the stator via a transfer channel in the rotor. The valve assembly provides a durable, virtually leak-proof system for delivery of a variety of fluids through the same delivery channel.

Abstract: A valve for controlling the rate of fluid flow therethrough by rotating a rotor about a spindle having an inlet bore in communication with an eccentrically oriented o-ring set into an eccentrically oriented slot formed in the rotor. The perimeter of the eccentric slot is modified to provide customized unique fluid flow response curves.

Abstract: A pressure compensating flow control device is disclosed which has a needle valve/spring assembly as a reference restriction which is in axial alignment with a reducing valve situated in a housing of the device. A piston and piston rod is provided in axial alignment with the needle valve and reducing valve to provide compensation for alterations to pressure differential about the piston. The piston rod has an internal channel to allow for fluid communication between inlet and outlet chambers and to allow for passive control of pressure differential. The device provides pressure control for low fluid flows and low pressures.
