Patent number: 7341236Abstract: A pilot operated valve has a main poppet that selectively controls flow of fluid between first and second ports in response to pressure in a control chamber on one side of the main poppet. The main poppet has an aperture extending between the control chamber and the first port. A pilot piston slides within the aperture and has the pilot passage with a pilot orifice and a first disk spring biases the pilot piston with respect to the main poppet. A pilot valve element selectively engages the pilot orifice to open and close the pilot passage and thereby controls motion of the main poppet. Forces from the first disk spring and a pressure differential between control and pilot chambers alter a position of the pilot valve seat with respect to the main poppet. The change in position compensates for effects on valve operation due to variation of the pressure at the two ports.Type: GrantFiled: March 7, 2006Date of Patent: March 11, 2008Assignee: HUSCO International, Inc.Inventors: Dwight B.

Patent number: 6149124Abstract: A pilot operated control valve has a body with an inlet and an outlet. A main valve poppet is movable within the body to selectively control flow of fluid between the inlet and outlet. The main valve poppet has a flexible diaphragm with a pilot passage therethrough which is opened and closed by movement of a pilot poppet. The diaphragm flexes due to a pressure differential that acts on the pilot poppet, which flexing compensates for adverse effects that the pressure differential has on the operation of the pilot poppet.Type: GrantFiled: May 3, 1999Date of Patent: November 21, 2000Assignee: Husco International, Inc.Inventor: Xiaolong Yang
