An inflation valve is provided and includes a valve defining main and command cavities and including first and second valve portions and a valve seat defining an outlet, a poppet disposed in the main cavity and including first and second rods to engage with the first valve portion and to extend through the valve seat and the second valve portion, respectively, and a piston disposed in the command cavity and a solenoid valve. The solenoid valve normally prevents main cavity-command cavity fluid flow to engage the poppet with the valve seat by fluid pressure acting on the poppet in the main cavity and permits the main cavity-command cavity fluid flow when energized to disengage the poppet from the valve seat by balanced fluid pressure acting on the poppet in the main cavity and on the piston in the command cavity to permit main cavity-outlet fluid flow.

A system for delivering fuel to an equipment fuel tank. The system includes a remote fuel storage tank and a valve assembly coupleable to the equipment fuel tank. The system includes a fuel supply line extending between the remote fuel storage tank and the valve assembly and a pneumatic valve disposed in the fuel supply line. The pneumatic valve can prevent flow of fuel into the fuel supply line or can enable flow of fuel into the fuel supply line. The valve assembly includes pressure tubes to detect changes in fuel level inside the equipment fuel tank. A switch actuates the pneumatic valve to prevent the flow of fluid in response to an overfilled position; and actuates the pneumatic valve to enable the flow of fluid in response to an underfilled position.

A T-joint includes a pipe body and a switch. The pipe body includes an inlet opening, a first outlet opening, a second outlet opening and a switch accommodating space communicating with each other. The switch is positioned into the switch accommodating space of the pipe body, and includes a pressed member and an outlet-selecting member. The pressed member and the outlet-selecting member are connected to each other. By pressing either a first pressed portion or a second pressed portion of the pressed member, the isolating member of the switch could be positioned to lead the inlet opening to communicate with a corresponding one of the first outlet opening and the second outlet opening.

A gas regulating and control system is provided that is configured to be received at a gas regulator installed at a remote location for remotely controlling the gas flow, the system including a gas control module including a plurality of sensors associated with the gas regulator, the plurality of sensors configured to sense a corresponding plurality of parameters associated with the gas regulator. The gas control module is configured to automatically turn off the gas to the gas regulator when one or more of the corresponding plurality sensed parameters is determined to be outside an acceptable range for the sensed parameter.

The switch is positioned into the switch accommodating space of the pipe body, and includes a pressed member and an outlet-selecting member. The pressed member and the outlet-selecting member are connected to each other. When a first pressed portion of the pressed member is pressed, an isolating member of the switch is positioned to isolate the inlet opening from the second outlet opening, but the first outlet opening communicates with the inlet opening, whereby a water flow merely outlets from the first outlet opening. When a second pressed portion of the pressed member is pressed, the isolating member of the switch is positioned to isolate the inlet opening from the first outlet opening, but the second outlet opening communicates with the inlet opening, whereby a water flow merely outlets from the second outlet opening.

An example actuator assembly includes a valve body having a body locating shoulder as a protrusion from an interior peripheral surface of the valve body, and an actuator having an end that is inserted into the valve body. The end has a first portion with a first diameter and a second portion with a second diameter that is larger than the first diameter, and the second portion includes a threaded region. A locating shoulder is between the first portion and the second portion of the end of the actuator arranged at a position where the first diameter changes to the second diameter. The locating shoulder mates with the body locating shoulder of the valve body when the actuator is inserted and screwed into the valve body to enable alignment of the valve body and the actuator.
