Pressure regulator having an integral pilot and self-relieving mechanism
A high flow pressure regulator valve is disclosed having an integral pilot valve. The disclosed valve includes a pressure regulating portion including inlet and outlet ports, a valve seat, valve disc and a spring for biasing the valve disc into engagement with the valve seat. The valve also includes a pilot valve portion positioned on the flow regulating portion. The pilot valve portion includes a pilot spring, a diaphragm and a pusher post. One end of the pusher post is positioned toward the diaphragm and a second end is disposed within an annulus region. The valve further includes a pressure path that enables selective fluid communication between the outlet port, the annulus, an inner chamber region disposed beneath the diaphragm, and an intermediate chamber disposed above the valve disc. Other embodiments are disclosed and claimed.
An adjustable economizer valve is disclosed that does not overlap the pressure build function, which allows a single valve to be used for both high and low gas use applications. The valve will economize well and reduces system pressure when needed in low use applications. The valve also provides maximum pressure build capacity when needed in high gas use applications. The valve seals off the pressure build outlet from the economizer connection with a seal around a pusher post disposed in the valve body. The pusher post has an internal flow path that is sealed by a floating device that can create a seal from diaphragm pressure and can open when diaphragm pressure is removed. In exemplary, non-limiting, embodiments, the floating device can be a ball or a disc plate.
A rotary gate valve includes first and second opposing housing members having coaxial pathways and defining a gate channel when joined together. A gate is positioned within the gate channel when the valve is in a closed position to prevent media from flowing through the pathways and rotationally displaced from the channel when the valve is in an open position to allow media to flow through the pathways. First and second annular primary sealing sleeves are disposed within the first and second housing members and are adapted to sealingly engage each other when the valve is in the open position, and with the gate valve when the valve is in the closed position. A secondary sealing member is disposed around an upper portion of the gate and secured between the housing members above the first and second annular primary sealing sleeves to prevent process media from entering the housing members.

An adjustable automatic recirculation valve includes a valve body, a main valve disk, a bypass valve and a dynamic adjustment assembly. The main valve disk is positioned within the valve body and opens in response to fluid flow between a main inlet and a main outlet. The bypass valve controls the flow of fluid between the main inlet and the recirculating outlet. A dynamic adjustment assembly, housed within the valve body controls the operating lift associated with the maximum opening of the bypass valve to regulate fluid flow capacity to the recirculating outlet.
A gate valve has support members that are attached to a main body structure of the gate valve adjacent to the valve gate opening. These support members are affixed on both sides of the valve gate opening radially around a gate sleeve.
