摘要: Manual overrides for valves are disclosed herein. An example apparatus includes an actuator to move a stem of a valve. The actuator includes a housing defining a bore and a piston disposed in the bore. The example apparatus also includes a rod movably coupled to the housing to extend into the bore, and the piston is to be movable via the rod or a fluid to flow into the bore. The example apparatus also includes a lock to hold the rod in a first position on the housing where the rod is to disable a supply of the fluid to the bore.

摘要: Dome-loaded pressure regulators are disclosed. An example pressure regulator includes a dome-loaded pressure regulating valve fluidly coupled to a pressure inlet, a pressure outlet, and a control pressure. The pressure regulating valve includes a piston, having a transverse bore defining a fluid path through the piston to fluidly couple the pressure inlet to the pressure outlet configured to engage a valve seat and to respond to the control pressure to control the flow of fluid between the pressure inlet and the pressure outlet via the valve seat.

摘要: Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.

摘要: Dome-loaded pressure regulators are disclosed. An example pressure regulator includes body having a pressure inlet and a pressure outlet. A piston is disposed in the body and fluidly coupled to the pressure inlet, the pressure outlet, and the pressure control inlet. The piston is configured to contact a valve seat and to control the flow of fluid from the pressure inlet to the pressure outlet in response to a pressure applied to a surface of the piston via the pressure control inlet.
