The armature is moveable relative to the sleeve and the housing, and the valve portion includes a valve, where the movement of the valve is controlled by the movement of the armature. The valve is biased towards an open position to provide a fluid pressure balance between multiple ports. | ||||||
| 73 | BALANCED VALVE TRIM AND METHOD OF REDUCING STEM FORCES ON A VALVE STEM | US14974103 | 2015-12-18 | US20170130868A1 | 2017-05-11 | Trenton Frank Jackson |
| Valve trim for a valve includes a valve plug having one or more balance ports located along the outer surface of a tapered nose portion of the valve plug. Each balance port is located to be downstream of the throat and spaced from the tip of the tapered nose portion of the valve plug. The valve trim may be use, for example, in a high recovery angle body valve. A high recovery valve with the valve trim may have better recovery performance as well as a smaller spike in stem force through the choked flow transition point. A method of reducing stem forces on a valve stem of sliding stem valve is also provided. | ||||||
| 74 | Balanced globe valve assembly | US14488939 | 2014-09-17 | US09371936B2 | 2016-06-21 | Chaitanya Morla |
| A balanced globe valve assembly includes a housing having an inlet and an outlet and a cage disposed within the housing between the inlet and the outlet. The cage includes a valve seat and at least one port formed therein. The balanced globe valve assembly further includes a valve member disposed within the cage and coupled to the housing. The valve member is movable within the cage between an open position in which the valve member is spaced from the valve seat and a closed position in which the valve member is seated within the valve seat so that the valve member blocks the at least one port. The valve member has a small opening formed therein to balance the valve member. | ||||||

| 79 | Balanced sleeve control choke | US625303 | 1990-12-07 | US5086808A | 1992-02-11 | Ronald G. Pettus |
| A balanced sleeve control choke includes a choke with inlet and outlet flow passages intersecting in a cylindrical flow chamber. A balanced external sleeve and cage trim configuration which vents downstream pressure to a balance chamber within the choke body includes an external sleeve with a wear sleeve of tungsten carbide shrink fitted therein is reciprocable within the flow chamber to control flow between the inlet and outlet flow passages. The external sleeve is closed at one end with a stem extending therefrom which is reciprocated by a handwheel operated travelling nut assembly. The external sleeve telescopes over a flow cage of composite construction secured within the flow chamber with a portion of the flow cage constructed of tungsten carbide with pressure balancing ports therethrough. The external sleeve has ports disposed within its wall which communicate downstream pressure to a balance chamber disposed thereabout. The flow cage has a seal neck extending from a closed upper end with a seal assembly disposed thereon which seals within the external sleeve and acts in conjunction with the balance chamber to eliminate any pressure forces on the travelling nut assembly. | ||||||
| 80 | Hydraulic control device | US930085 | 1986-11-12 | US4738278A | 1988-04-19 | Karl Sauder |
| A hydraulic control device consists of a housing, a control slide valve displaceable in a bore of the housing, and a control ring. Axial displacement of the control slide valve makes it possible to connect together or to disconnect various connecting lines depending upon the position of the valve. Located in an annular chamber, formed between a section of the housing bore and the control slide valve is a control ring arranged coaxially with the valve and guided displaceably thereupon. Valve seats are spaced axially from each other both in the housing bore and on the control slide valve. The control ring comprises inner mating surfaces and outer mating surfaces cooperating with the valve seats. Provided between the two valve seats in the control slide valve is a flow channel running therein which is closed at one end depending upon the position of the control ring. The latter is held by the pressure of the flowing medium in the appropriate closed position, but the changeover may be effected independently of the pressure since no axial forces are applied to the control slide valve by the flowing medium. | ||||||
