  • Control valve pressure bleed inspection port
    Patent number: 6695000
    Abstract: A valve with an integral means for bleeding internal pressure prior to separation of a bonnet for the valve from its engagement with the valve body, provided by a bore through the valve body. This allows the internal pressure of the valve to equalize with atmospheric pressure prior to complete disassembly of the bonnet from the valve body. The bore through the valve body also serves as a leak detector, by providing a path for fluids passing through the valve to leak to the exterior of the valve body in the event of a failure of the seal between the bonnet and the valve body, which can readily be detected by passersby upon inspection of the exposed end of the bore at the exterior of the valve body.

  • Valve actuator with instrument mounting manifold
    Patent number: 5853022
    Abstract: A valve actuator with an instrument mounting pad and a manifold in a power module and yoke combination for mounting a valve controller instrument without tubing or mounting brackets. A cover encloses the feedback linkage between the actuator and instrument. The actuator includes a second instrument mounting pad and manifold so the power module is reversible to accommodate fail-safe opened or fail-safe closed valve conditions. A valve actuator and instrument combination is no higher than the actuator alone.
