A fluid flow control device includes a valve body defining an inlet, an outlet, a throat disposed between the inlet and the outlet, and a bonnet opening, a control element having a valve plug and an elongated stem coupled to the valve plug, an extension bonnet coupled to the bonnet opening, a bellows disposed in the extension bonnet, and a bellows nut threaded onto the stem to secure the bellows in the extension bonnet and form a seal around the stem. The bellows nut includes a first surface, a second surface, a throughbore extending between the first surface and a second surface receiving the stem, and a tapered channel extending from the first surface toward the second surface. The tapered channel comprises a first width formed by the first surface and a second width that is greater than the first width for receiving a tool and facilitating placement.

An apparatus for removing a broken pressure balanced valve cartridge from the valve body without breakage of the cartridge. This apparatus operates to separate the inner cartridge piece from the valve by exerting primarily axial forces on the cartridge during removal. The apparatus utilizes a pair of long, low profile forks with hooks on the end that are designed to be inserted in between the valve body and inner piece of a broken pressure-balanced valve cartridge. These forks are connected to an alignment device, which aligns the forks once they have been inserted in between the valve body and pressure-balanced valve cartridge, to the specific angle required to allow the hooks to engage the inner piece of the cartridge for removal. Running through the alignment device is a threaded rod with a handle on the top and a swivel block on the bottom. The threaded rod generates the axial force to remove the broken pressure balanced valve cartridge from the valve body.

The present invention is a novel backflow meter Seatdriver apparatus which is much like a screwdriver. Its novel direct connection of the Seat Head slot, Driver Shaft and the Driver Handle work together creating one apparatus known as the Seatdriver allowing for easy installation and removal of backflow valve seats. This apparatus functions as a two in one device providing a check valve seat connector on one end and a relief valve seat connector on the other end. The Seatdriver channels on the handle matches the seat part profile which reduces the Camming Out effect which in turn increases the hand torque force, increases thread alignments, and holds the valve part in place during the replacement.

The present invention relates generally to the field of accessories for use with impact drivers that are useful for removing a valve seat from a fitting. The device has a first end, a second end and a central body portion. The first end has a shaft that allows the device to be attached to the chuck of an impact driver or drill. The second end has a head that can be placed within a valve seat. Once inserted into the valve seat, the impact driver or drill can be used to spin the device to remove the valve seat from the surrounding fixture.

A valve repair tool is a rod having a forked valve stem extractor on one end and a cap at the other end with a flare fitting rounding part built into it.
