摘要： A valve assembly includes a solenoid can having an internal coil. A valve body connected to the solenoid can includes an inlet port and a first valve seat. An axially adjustable retainer threadably connected to the valve body includes an end portion defining a second valve seat. A homogenous valve member/armature slidably disposed in the valve body moves in the presence of a coil generated magnetic flux between valve closed and valve open positions. A valve member/armature first surface area is in fluid communication with a pressurized fluid through the inlet port. A valve member/armature second surface area is in fluid communication with the pressurized fluid in the valve closed position. The first surface area is equal to the second surface area and the pressurized fluid acts equally on the first and second surface areas defining a pressure balanced condition in the valve closed position.

摘要： A solenoid actuated valve assembly includes a valve body having a slidable main valve member and a pilot valve body mechanically connected to the valve body including a slidable pilot valve member. A first solenoid operated valve connected to the pilot valve body when energized directs pressurized fluid to move the pilot valve member between pilot valve open and closed positions. A second solenoid operated valve connected to the valve body when simultaneously energized with the first valve directs the fluid to move the main valve member between valve closed and open positions. A third solenoid operated valve connected to the pilot valve body when energized and when both the first and second solenoid operated valves are de-energized directs the fluid to move the pilot valve to the pilot valve open position and the main valve member to the valve closed position.

摘要： A proportional pressure controller includes a body having inlet, outlet, and exhaust ports. A fill valve communicates with pressurized fluid in the inlet port. A dump valve communicates with pressurized fluid from the fill valve. An inlet poppet valve opens by pressurized fluid through the fill valve. An exhaust poppet valve when closed isolates pressurized fluid from the exhaust port. An outlet flow passage communicates with pressurized fluid when the inlet poppet valve is open, and communicates with the outlet port and an exhaust/outlet common passage. An isolation valve assembly selectively isolates fluid flow to and from the inlet port or the exhaust port to achieve a zero pressure condition.

摘要： A diaphragm sealed, pressure balanced valve assembly includes a valve body and a cartridge connected to the valve body. The cartridge includes a cartridge loading end having a retaining member engaged to the cartridge loading end. A valve member slides coaxial to a longitudinal axis of the valve body. A resilient material first diaphragm is connected to and extends diametrically outward from the valve member having a diaphragm body clasped between the retaining member and the cartridge loading end, creating a first diaphragm fluid pressure boundary. A resilient material second diaphragm is connected to and extends diametrically outward from the valve member at an opposite end of the valve member with respect to the first diaphragm and has a diaphragm body clasped between first and second adjustable retention members, creating a second diaphragm fluid pressure boundary.
