Abstract: A ball valve includes: a main body having a fluid inlet passage, a fluid outlet passage, and a column-shaped depression communicating with these passages and opening upward; a ball including a fluid communication passage and disposed at the column-shaped depression of the main body rotatably about a reference axis; an operating mechanism configured to cause the ball to rotate about the reference axis; a ball seat having a required opening on a peripheral wall thereof and disposed between the ball and the main body; a ball seat presser configured to press the ball seat; and a pressing screw configured to press the ball seat presser downward. The ball is rotated to achieve communication and cutoff. The ball seat has a substantially frustoconical shape having a bottom surface larger than a bottom of the depression in diameter, and an upper surface slightly smaller than the bottom surface in diameter.

Abstract: A valve assembly includes a valve body with an upstream inlet and a downstream outlet and a valve element which is engageable with and disengageable from a valve seat to open and close the valve assembly. The valve body defines a bore with an axis for receiving the valve element. At least part of the bore and of the valve element have cooperating shapes which permit axial movement of the valve element in the bore and prevent rotation of the valve element in the bore. A rotatable actuator is provided, with a connection between the actuator and the valve element operable to convert rotation of the actuator into axial translation of the valve element.

Abstract: A sprayhead includes a body having a first end and a second end opposite the first end. The body includes a fluid inlet proximate the first end and a fluid outlet proximate the second end. The sprayhead includes a first disc fixed to the body and a second disc moveably coupled to the body. Rotation of the second disc relative to the first disc causes a first response. Translation of the second disc relative to the first disc causes a second response.

Abstract: Sleeve valves include a valve body having an inner surface and outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet; a sleeve disposed at least partially within the body cavity, the sleeve including at least one opening fluidly connecting the inlet to the outlet; a gate proximate to the sleeve and movable over a portion of the sleeve including the at least one opening, the gate including at least one front stop and at least one back stop connected to the gate; and a drive assembly including at least one drive line having a drive shaft and a sync cam, the sync cam of each at least one drive line movably positioned on the drive shaft and between one of the at least one front stop and one of the at least one back stop.

Abstract: Valves include a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet; a gate movably coupled to the valve body and moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a cam stop; and a drive assembly, the drive assembly including a drive shaft and a sync cam, the sync cam of the drive assembly movably positioned on the drive shaft and slidably positioned relative to the cam stop.

Abstract: A service valve and cap assembly is disclosed. The service valve comprises a valve stem that is inserted into a valve body. An upper portion of the valve body defines a collar selectively formable between a first installation inner diameter to a second retention inner diameter. A service valve sealing cap includes a base portion and a generally annular sealing portion. An annular shoulder is formed on the sealing portion inner diameter, such that the radially inner diameter of the shoulder portion is less than the collar first outer diameter, and is greater than the collar second outer diameter.

Abstract: An improved bottom entry cryogenic valve, with single piece cast body, that provides for easy and efficient removal of the valve stem and valve seat components without removing the valve body from the fluid circuit. The valve body forms the housing and has a top end, a main body section and a bottom entry end. The main body section has fluid entry and fluid exit openings. A bonnet nut is attached to the valve body top end. A body ring is attached at the bottom entry end. A valve stem extends axially through the bonnet nut, with a top portion exposed with a hand wheel attached thereon. The valve stern has a mid portion, a flange portion and a threaded bottom end located in the main body section of the valve body. The valve stem mid portion supports a valve seal member and a seal nut/bearing. The valve seal member is to prevent fluid from flowing through the valve body when the valve is in a closed position. The seal nut/bearing acts to restrict fluid from entering the top end portion of the valve body.
