  • Patent number: 11118695
    Abstract: Multiport valve with outlets transverse to the inlet useful as a coker switch valve. A sealed lower sleeve assembly provides semi-trunnion ball support. An upper part of the outlet seat recesses is formed in the bonnet, and a lower part in the valve body, which together bias a resilient member to load the seats, independently of end connections. Before bonnet assembly, when the ball is rotated to face a body outlet, there is sufficient space in the seat recesses to insert the seat, slide the seat onto the ball, and then insert the resilient member. When all the seats and resilient members are in place, engagement of the bonnet biases the upper part of the resilient members to load the seat. In valve operation, an enlarged ball outlet bore can straddle two outlet ports and maintain process media flow during switching. Also, methods of assembling, operating, and servicing the valve.

  • Patent number: 8297303
    Abstract: A self cleaning valve assembly includes a valve body having an internal valve cavity. A cylinder member received in the valve cavity has a first sealing surface and a cylinder wall, and divides the valve cavity into a liquid-free cavity portion and a flow cavity portion. A spindle includes a spindle body contacting the first sealing surface to continuously prevent pressurized fluid in the flow cavity portion from entering the liquid-free cavity portion. A spindle piston end has a wiper member in a receiving groove frictionally contacting the cylinder wall. A handle pinned to the valve assembly directly contacts the piston end. Handle rotation displaces the spindle from a valve closed to a valve open position permitting pressurized fluid flow into the flow cavity portion. The wiper member wipes a contaminant off the cylinder wall and further prevents contaminant entrance into the liquid-free cavity portion.

  • Patent number: 8251086
    Abstract: A rotary gate valve includes first and second opposing housing members having coaxial pathways and defining a gate channel when joined together. A gate is positioned within the gate channel when the valve is in a closed position to prevent media from flowing through the pathways and rotationally displaced from the channel when the valve is in an open position to allow media to flow through the pathways. First and second annular primary sealing sleeves are disposed within the first and second housing members and are adapted to sealingly engage each other when the valve is in the open position, and with the gate valve when the valve is in the closed position. A secondary sealing member is disposed around an upper portion of the gate and secured between the housing members above the first and second annular primary sealing sleeves to prevent process media from entering the housing members.

  • Patent number: 7694934
    Abstract: A diaphragm valve is disclosed that is adapted to reduce debris in the flow paths, reduce the water hammer effect, reduce the energy lost during flow, and/or improve bleed operation. The diaphragm valve includes at least two seals that are configured to permit multi-stage sealing of an opening in a diaphragm valve seat. The initial sealing stage blocks some but not all fluid flow through the opening, and the final sealing stage blocks fluid flow through the opening. The use of two sealing stages can reduce the water hammer effect by increasing the time over which sealing occurs.

  • Publication number: 20090229673
    Abstract: A solenoid valve control apparatus has a solenoid valve having first and second solenoid valves that output first and second solenoid pressures respectively, a pressure regulation valve that works with the first and second solenoid pressures being working signal pressures, and a foreign matter removal control means that removes a foreign matter that adheres to a valve open/close portion of the solenoid valve. Each of the first and second solenoid valves has a solenoid coil that drives a plunger inside the solenoid valve in accordance with an application current. The foreign matter removal control means is configured so that when applying the rectangular-wave current, which performs a reciprocating movement of the plunger and removes the foreign matter, to the solenoid coil of one solenoid valve of the first and second solenoid valves, a current application to the solenoid coil of the other solenoid valve, by which the solenoid pressure becomes a maximum pressure range, is maintained.
