Whatever Your Pressure Or Line Size TDW Has Your Pipeline Valve Solution.
TDW has designed and manufactures a family of valves for use in tapping and plugging operations when recovery of the valve upon completion of work is desired. Our SHORTCUTT® Valves and SANDWICH® Valves are industry standard tapping valves used on everything from 2-inch low-pressure gas distribution systems to 48-inch high-pressure crude oil lines.
Our valves are low profile gate valves designed to minimize the travel distance required for the tapping machine to complete the tap. Most valves require an operational safety factor of pressure equalization on both sides of the disc before opening, and our valves feature an internal bypass mechanism to accomplish that.
SANDWICH® Valves - SANDWICH® Valves are designed for use with TDW Tapping Machines, TDW STOPPLE® Plugging Machines, and fittings with LOCK-O-RING® Flanges during hot tapping and plugging operations.
Distribution Valves - 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.
