Abstract: A housing has a housing main body that defines an internal space therein, an inlet port that fluidly connects the internal space and an outside of the housing main body to each other, and a relief port that fluidly connects the internal space and the outside of the housing main body to each other. Coolant water flows into the housing through the inlet port. A relief valve is disposed in the relief port and configured to selectively allow and block fluid communication between the internal space and the outside of the housing main body via the relief port by selectively opening and closing the relief port in accordance with conditions. A valve has a valve body rotatable about a rotation axis in the internal space, and a shaft disposed along the rotation axis. A covering portion is configured to cover the relief valve not to be visible through the inlet port.

Abstract: Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that substantially prevents fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be reconnected to each other after being disconnected from each other.

Abstract: A dielectric union ball valve utilizes a non-conductive separation sleeve to prevent contact between the union and the nut of a dielectric valve assembly. The valve assembly can optionally include an independently operated drain valve port to permit draining of the valve assembly. The use and positioning of a non-conductive separation sleeve mitigates potential galvanic reaction between dissimilar pipes and/or fittings that are connected to the valve assembly.

Abstract: A trunnion ball valve provides a reliable seal when closed, while minimizing or eliminating frictional resistance during rotation of the ball. A pressurization chamber behind the upstream valve seat can be interconnected by one or more pressurization valves with either the upstream or the downstream process fluid. The interconnection can be via a single 3-way valve. When the valve is closed and the ball is fixed in orientation, the pressurization chamber is automatically connected to the upstream process fluid, thereby pressing the seat against the ball and ensuring a reliable seal. While the ball is being rotated, the pressurization chamber is automatically connected to the downstream process fluid, thereby substantially eliminating valve seat friction. Connection to the downstream process fluid can include connection to a small space in front of the upstream seat. An electronic controller can control both valve stem rotation and the pressurization valves.

Abstract: A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.
