  • Pneumatic snap pilot
    Patent number: 6497246
    Abstract: A snap pilot used to pneumatically energize and de-energize a control device, such as a valve. The pilot has two valves—one to admit pilot pressure, and one to exhaust pressure. The pilot incorporates valves having an elastomeric seal but maintaining the precision of metal to metal contact. In the preferred embodiment, the elastomeric seal is an O-ring placed in a groove, without adhesive, having only a small amount of deflection when the seat is closed, whereby simultaneous metal-to-metal and elastomer-to-metal contact is achieved.
    Type: Grant
    Filed: June 5, 2001
    Date of Patent: December 24, 2002
    Assignee: Delaware Capital Formation, Inc.

  • V-ball control valve
    Patent number: 6378842
    Abstract: A V-ball-type control valve having: a valve body installable in a piping system; a V-ball-type valve element rotatably positioned in the valve body; a valve shaft extending from the V-ball-valve element; and a bonnet removably attachable to the valve body. The valve shaft is rotatably positionable through the bonnet such that the bonnet, the valve shaft, and the valve ball element can all be removed from the valve body without removing the valve body from the piping system.
