Tulsa Valve

Tulsa Valve pig valves are designed to launch and receive spherical pigs so pipelines remain clean and serviceable for the transportation of gas or liquid products. Periodic use of the pig ball valves leads to trouble-free scraping and eliminates the additional expense of hot oil treatments and extended downtime.

Tulsa Valve's pig ball valve provides continuous flow capability in all valve positions by isolating the pig chamber from the flow line, thereby not closing in the flow line. It is utilized where pumps or flow cannot be interrupted during the pigging operation. The bypass is built integrally into the valve body and provides 35% or more flow capacity to minimize pressure drops during the pigging operation.

The valve bypass design also allows for loading or unloading of the pig chamber while the valve is in the normal flowing posi-tion. This feature minimizes the amount of time the valve is in the flow restrictive launching or receiving position.

Tulsa Valve's pig ball valve systems offer a number of advantages over fabricated trap systems:

The simple design is easier to install and offers greater accessibility and a reduction in maintenance costs.

Down-time is saved in that it is not necessary to shut in the flow line in the launching and receiving operation.

Tulsa Valve's compact design requires a much smaller space than fabricated trap systems. This is a very important con-sideration on offshore platforms where space is very critical.

Tulsa Valve's system simplifies field operation and applications of corrosion inhibitors.

Tulsa Valve pig ball valves are available in flanged, threaded end, and butt-weld connections in sizes 2" thru 12".
