Abstract: A valve seat assembly for use in a fluid control valve. The valve seat assembly includes a pad holder and a support ring. The pad holder includes a support body configured to support a seat pad and a plurality of alignment struts projecting radially outwardly from the support body. The support ring extends around the radially outer perimeter of the alignment struts. The pad holder slides into and out of an operative position in the support ring.

Abstract: A control assembly for converting a “fail-close” regulator to a “fail-open” regulator, or vice versa, without having to modify or reconfigure a casing of the regulator includes a control member, a central rod, and a spring disposed between first and second spring seats. A regulator including the control assembly includes a valve body and an actuator casing, the valve body defining a fluid flow-path. The control member is slidably disposed within the actuator casing and adapted for displacement relative to the valve body for controlling the flow of fluid through the flow-path. The spring and spring seats are disposed about the central rod, such that the spring biases the control member into a predetermined position relative to the regulator casing.

CPC classification number: F16K1/46 , G05D16/0638
Abstract: A sealing disk mounting assembly for a regulator includes a mounting member adapted to be operatively attached to a tubular member of a control member assembly of a regulator, a disk holder operatively attached to the mounting member, and an annular sealing disk disposed in an annular channel that is formed between the mounting member and the disk holder. The annular sealing disk is mechanically retained between the mounting member and the disk holder by compressive forces.

Abstract: A flow path velocity modifier allows a control member of a control valve to operate very close to a seat ring while reducing or eliminating restricted flow areas, which results in greatly reduced flow velocity fluctuations, which results in smoother flow, between the sealing element and the seat ring. As a result, sealing elements made of relatively soft materials may be used without fear of damage from high flow velocities.
