Pressure Releasing Tools

Pressure Releasing Tools • 11396 / 11396S
Patent# 7,725,997-B2

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. •  For Industrial Use Only. •

*  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.

Warning!
Maximum pressure Discharge for 11396/11396S is 2,500 psi.
• For higher pressure release applications, refer to Dualco part # 10720, which is rated for 10,000 psi.

It is important to note the application pressure involved, the service type, operations and manufactures recommendations when choosing a Pressure Release Tool.
