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.
Whatever your pressure, whatever your line size, use the links below to get more information on TDW’s extensive range of tapping valves.
