TDW's line of distribution valves includes the SHORTCUTT® 500 Valve, SHORTCUTT Valve and SHORTSTOPP® Valve. All are designed for use with the SHORTSTOPP Plugging Systems for Hot Tapping and SHORTSTOPP Plugging Operations.
They are temporary valves that are used with TDW drilling or tapping machines and SHORTSTOPP Plugging Machines. Their compact size reduces the travel required for the drilling machine's boring bar to make taps. The valves are full opening, permitting passage of TDW drills, hole saws, cutters, plugging heads and completion plugs.
The SHORTCUTT Valve body is constructed of pressure-quality cast iron. The SHORTSTOPP Valve body is constructed of aluminum. SHORTCUTT 500 Valves are constructed of ductile iron.
The 2" and 3" (DN 50mm and DN 80mm) SHORTCUTT 500 Valves replace the SHORTCUTT 2" and 3" (50mm and 80mm) valves to accommodate higher pressure lines. The maximum working pressure is 500 psi at 100°F (35 bar at 38°C) or 460 psi at 180°F (31 bar at 82°C).
The SHORTCUTT Valves accommodate 4" through 12" (DN 100mm - DN 300mm) lines. The maximum working pressure is 275 psi at 100°F (19 bar at 38°C) or 245 psi at 180°F (17 bar at 82°C). These valve sizes meet ASME Class 150 bolt pattern.
The SHORTSTOPP Valves accommodate 2" through 6" (DN 50mm - DN 150mm) through 152mm) lines. The maximum working pressure of the 2" and 3" (50mm and 80mm) is 500 psi at 100°F (35 bar at 38°C) or 460 psi at 180°F (31 bar at 82°C). The maximum working pressure of the 4" and 6" (100mm and 150mm) is 275 psi at 100°F (19 bar at 38°C) or 245 psi at 180°F (16 bar at 82°C).
