Dualco Pressure Releasing Tools
Giant Button Head Fitting
Pressure Releasing Tools • 11396 / 11396S
One of the basic procedures required in good valve maintenance is the replacement of corroded or damaged button head lubrication fittings.
Many lubricated valves are designed with either one or two internal check valves, which are located in the valve beneath the button head fitting. If these internal check valves are present and holding pressure, it is possible to remove the button head fitting from the valve and replace it with a new one. In the past, it was impractical to be sure if the internal check valves were holding pressure or not.
These tools are unique safety devices designed to slide over the button head fitting. They are secured by turning the “T” handle in a clockwise direction, rotating the stinger down into the fitting. First the top and then, if present, the second check ball is depressed against its individual spring within the fitting. This allows any residual gas, liquid, or other material to bleed off, and the check ball(s) to reseal. If the “blow” (gas) or “flow” (liquid) does not cease, the fitting can be resealed by rotating the “T” handle counter-clockwise until the fitting reseals.
This Tool works well with Vent Cap Fittings that have Button Heads in low pressure applications, and with Single Check Giant Button Head Fittings.
* 3-¼” = Stem Retracted, in clearance of button head. This dimension allows for just enough stem clearance for the tool to be coupled onto the button head fitting. If necessary, the stem will retract farther.
GBH Configuration Options
1. Giant Button Head Fitting Pressure Releasing Tool.
2. Standard Button Head Fitting Pressure Releasing Tool.
3. Stem Packing Assembly Option for either 1 or 2.
4. Tools can be manufactured utilizing various materials such as, but not limited to, carbon steel, brass, stainless steel, Inconel, etc.
5. Bleed release port cover for either 1 or 2.
6. Locking retainer to prevent Pressure Releasing Tool from dislodging from Button Head Fitting.
