摘要： There is presented an on-off pilot stage valve arrangement (20) for controlling at least one main stage valve (9a, 9b, 9c, 9d). The on-off pilot stage valve arrangement comprises a first pilot valve (18) discretely operable between two states, an on and an off state, the first pilot valve having an input at which there is a first pressure and an output connected to the main stage valve, a second pilot valve (14) discretely operable between two states, an on and an off state, the second pilot stage valve having an input at which there is a second pressure and an output connected to said main stage valve. Both the valves are configured to be set in one of the two states in case the arrangement loses power.

摘要： A fail fixed actuator utilizing a rotary cam and servo are provided herein. A rod 10 comprises a piston 11 and a fluid channel 12 extending axially through the rod. A servo orifice 16 at a surface of the rod 10 is in fluid communication with the fluid channel 12. A cam 20 covers a portion of the rod 10 in close fitting relation, and comprises a groove 22. The servo orifice 16 and a portion of the groove 22 combine to form an aperture, movement of at least one of the cam 20 and rod 10 varying the size of the aperture. A piston chamber 13, containing the piston 11, comprises a high pressure chamber 14 and a servo pressure chamber 15, the servo pressure chamber being in fluid communication with the fluid channel 12.

摘要： A poppet valve assembly to control a pneumatic actuator may include a housing having a central bore. A first module may be disposed within the central bore, and the first module may have a first and second poppet valve. A second module may also be disposed within the central bore, and the second module may have a third and fourth poppet valve. A supply of pressurized fluid may be in fluid communication with a plurality of control valves such that pressurized fluid from the control valves opens and closes the poppet valves. The supply of pressurized fluid may also be in fluid communication with the first module and the second module such that the opening and closing of the poppet valves controls the position of the pneumatic actuator.
