摘要： A pilot assembly is configured for use with various types of flow controls. These configurations include a manifold with an internal flow network that connects pilot valves and an adjustable orifice. The pilot valves may have a fixed and variable differential pressure. In one implementation, the manifold comprises a pair of separable blocks, one each that includes part of the internal flow network. This construction also permits the manifold to expand with, for example, and additional block for an additional pilot valve. This feature configures the manifold for use in working monitor systems or those systems that deploy multi-stage pressure regulation.

摘要： The present application relates to a valve for a cryogenic gas. The valve includes a body with a main inlet, a main outlet, and a main passage. The valve also includes a main shutter for the main passage, the main shutter including an auxiliary inlet, an auxiliary outlet, and an auxiliary passage, in which an auxiliary shutter is arranged, which includes a closing surface configured to close the auxiliary outlet and be able to drive the main shutter in the closing direction, and a drive surface configured to drive the main shutter in the opening direction, while resting on the edge of the auxiliary inlet and blocking the auxiliary inlet partially in order to brake the flow there. The drive surface is formed by drive lugs which are connected to a head of the auxiliary shutter. The lugs form a bayonet coupling between the shutters. The present application also relates to an electrovalve.

摘要： A service valve for a valve body includes a base rotatable between an open orientation and a closed orientation relative to the valve body. When the base is in the open orientation, the service valve allows fluid flow into the valve body through the service valve. When the base is in the closed orientation, the service valve blocks the fluid flow into the valve body through the service valve. The service valve further includes a tab extending from the base. The tab prevents removal of a cover from the valve body when the base is in the open orientation.

摘要： A valve assembly includes a valve body with an upstream inlet and a downstream outlet and a valve element which is engageable with and disengageable from a valve seat to open and close the valve assembly. The valve body defines a bore with an axis for receiving the valve element. At least part of the bore and of the valve element have cooperating shapes which permit axial movement of the valve element in the bore and prevent rotation of the valve element in the bore. A rotatable actuator is provided, with a connection between the actuator and the valve element operable to convert rotation of the actuator into axial translation of the valve element.

摘要： A valve has a major valve closure member with a valve stem for opening and closing a major port in a valve chamber. An alternate flow path extends through the major valve closing member. Flow is controlled through the alternate flow path by directing a minor valve actuating fluid through the valve stem to apply pressure on a minor valve piston in the major valve closure member to move a minor valve closure member in the major valve closure member between a closed mode in which the minor valve closure member closes the alternate flow path and an opened mode in which the minor valve closure member opens the alternate flow path. The minor valve actuating fluid is sealed from the alternate flow path by a flexible diaphragm positioned between the minor valve actuating fluid and the minor valve piston, so the pressure of the minor valve actuating fluid is applied to the minor valve piston via the flexible diaphragm.
