A multi-stage pressure regulation system, device and associated methodology for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, and an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core.

A pressure regulator has a housing with an inlet, an outlet and a valve seat. A regulator sleeve is arranged within the housing and defines a flow channel from an upstream end adapted for cooperating with the valve seat towards a downstream end associated with the outlet. A spring biases the regulator sleeve towards the outlet. The downstream end of the flow channel tapers outwardly.

An oil pressure supply device supplies, to an oil chamber, an oil pressure generated by suctioning oil from an oil source with an oil pump. The oil pressure supply device includes a first oil passage connected to a suction side of the oil pump; a first check valve provided in the first oil passage and configured to close the first oil passage and prevent oil from moving to the oil source side when the oil pump is stopped; a second oil passage connected to a discharge side of the oil pump; and a second check valve provided in the second oil passage and configured to close the second oil passage and prevent oil from moving to the oil pump side when the oil pump is stopped. When the oil pump is stopped, the second check valve closes the second oil passage earlier than the first check valve closes the first oil passage.

A pressure regulator including a closure resisting mechanism that increases the total closure resisting force of a closure element to prevent the closure element from moving into a closed position until a predetermined pressure set point is reached. The closure resisting mechanism operates automatically and is spring actuated in response to pressure within a fluid pathway of the regulator. The closure resisting mechanism is disposed external to the fluid pathway so as not to impede fluid flow.

A pressure regulator for use in an elbow connector for use with a sprinkler assembly including a pressure responsive member, movably mounted in the elbow connector and movable from an open position allowing flow of water into the sprinkler assembly and a closed position where the bottom edge of the pressure responsive member blocks the flow of water into the sprinkler assembly. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.

A reject valve of a reverse osmosis device, which is especially suited for brackish water reverse osmosis devices, which require a low system pressure less than 15bar. The valve keeps the system pressure substantially constant in a pre-defined range of the reject volume. The size of the inflow channel is adjusted by a spring-operated cone, which never entirely closes the channel, which forms a constant throttle until the pressure of the inflow has risen to approximately three quarters of the pressure arranged by the spring and prevailing at maximum volume of the reject flow. This operation is arranged structurally such that onto the shaft of the cone is fixedly supported a transverse plate abutting the inner wall of the body, which as pressed by the compression spring is supported by the end of an element connected to the end of the body, wherein the cone is in its lowest position.

A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

Embodiments described herein relate to a pressure-regulating device, systems that include the device, and related methods. For example, the pressure-regulating device may receive gas from a gas supply at a first pressure (e.g., on a supply side of the pressure-regulating device) and may regulate or reduce the pressure of the received gas to a selected or suitable second, different pressure.
