Tulsa Valve Shut-Off Pig Valves are designed first and foremost as a state of the art Shutoff Valve. Each aspect of the valve is engineered to perform under the harshest conditions. The valve is designed as a trunnion mounted ball valve. As indicated from the name, the valve completely shuts off the flow of the piping and can be used as a single block and bleed or double block and bleed valve. For certain applications a by-pass can be installed. The Shut-Off Pig Valve is bi-directional and can be used as both a launcher or a receiver.

• Trunnion mounted ball
• Proven shut-off design with energized upstream sealing seat
• Reduces the number of valves and controls required in traditional pig launching skids
• Multiple pig launching systems available direct from the factory.
• Automatic body cavity venting downstream provided by arranged seats
• Offers a wide range of fl uid compatibility and flexibility due to lip seal or o-ring designs
