Abstract: An automatic valve includes a housing having an inlet passage and a passage to outlet, a linearly movable shaft disposed in the housing having two stops separated by a predetermined distance, a hydraulic unit connected to the housing and to the linearly movable shaft, and a sealing flange having at least one aperture accommodating the linearly movable shaft. The sealing flange being movable on the linearly movable shaft to close and open the passage to outlet through force of one of the stops on the sealing flange, the linearly movable shaft being biased to urge the sealing flange toward the passage to outlet by contact with one of the stops wherein the sealing flange in position to close the passage to outlet from the inlet passage despite limited movement of the linearly movable shaft.

Abstract: A fluid control valve has a valve member which, on closing creates a stagnation zone between the valve member and a surface within the valve. In the stagnation zone fluid pressure is greater than it is in an adjacent constriction zone. This causes the valve to close slowly, thereby reducing the likelihood that water hammer will occur on closure of the valve. The design of the valve member also reduces resonances which can cause annoying noises and premature wear. A flow restriction chamber further slows closure of the valve. The fluid control valve may be controlled by a conventional 3-way pilot valve. Preferably the fluid control valve is used with a pilot valve according to the invention having a rocker member which, on actuation, first closes an inlet valve member and then opens an outlet valve member. The pilot valve may be used in other situations where a 3-way valve is needed.

Abstract translation: 流体控制阀具有阀构件，其在闭合时在阀构件和阀内的表面之间形成停滞区。 在停滞区域中，流体压力大于相邻收缩区域中的压力。 这导致阀门缓慢关闭，从而降低了阀门关闭时水锤发生的可能性。 阀构件的设计还减少了可能导致烦人的噪音和过早磨损的共振。 流量限制室进一步减慢了阀的关闭。 流体控制阀可以由常规的三通先导阀来控制。 优选地，流体控制阀与根据本发明的先导阀一起使用，其具有摇动构件，所述摇动构件在致动时首先关闭入口阀构件，然后打开出口阀构件。 先导阀可用于需要三通阀的其他情况。

Abstract: A positioner and method for generating an output signal for setting a controlled object to a control condition corresponding to an input signal, including a memory unit for storing a conversion relation for converting the input signal to a command signal; a signal conversion unit for converting the input signal to the command signal based on the conversion relation; a control unit for generating the output signal for controlling the controlled object corresponding to the command signal; and a setting unit for adjusting the command signal to obtain a desired control condition for each of a plurality of selected input signals, thereby generating a modified conversion relation between the input signal and the command signal. The modified conversion relation generated by the setting unit is stored in the memory unit as the conversion relation.

Abstract: An apparatus and method for regulating the pressure of fluid flowing though a conduit system according to which a valve seat is formed in a lower housing connecting in the conduit system with the seat extending between an upstream portion of the system and a downstream portion of the system. A valve stem is mounted in the lower housing for axial movement in the lower housing and one end of the stem is connected to a valve head. Two spaced membranes are mounted in the upper housing to define two chambers, and the membranes are connected to the valve stem . The downstream portion of the conduit system is connected to one of the chambers to apply a load to of the membranes in proportion to the fluid pressure in the downstream portion so that changes in the fluid pressure in the downstream portion causes corresponding changes to the load on the one membrane, corresponding movement of the valve stem and the valve head, and corresponding changes to the fluid flow through the lower housing. The upstream portion of the conduit system is connected to the other chamber to apply a load to the other membrane in proportion to the fluid pressure in the upstream portion so that changes in the upstream pressure causes corresponding changes in the load on the other membrane, corresponding movement of the valve stem and the valve head, and corresponding changes to the fluid flow through the lower housing.

Abstract: A pilot-operated, pressure-loaded, movable diaphragm-type gas-flow regulator valve is shown which is used in flow control applications. A regulator body internal port arrangement interconnects two independent throttling mechanisms in series. Two throttle plates are located within the regulator valve body relative to an inlet chamber and an outlet chamber. A movable diaphragm is positioned relative to a throttle plate by a separate pilot control system to vary the area of throttle plate exposed to flow, and thus, the flow rate of the regulator valve. The throttle plates each have drilled flow apertures which control flow through the valve. Smaller flow apertures are opened before larger flow apertures as the valve diaphragm lifts, thereby ensuring stability at low-flow conditions, while providing high capacity at maximum diaphragm lift. The configuration of the throttle plates, the inlet chamber, and the outlet chamber substantially reduces operational noise of the gas-flow regulator by minimizing turbulent flow within the regulator valve body.
