Butterfly valves are valves that isolate or regulate the flow of a fluid. The closing mechanism is a disc that rotates 90 degrees from open to close or vice versa. They are part of the family of valves called quarter-turn. Butterfly valves have a small footprint in the piping when compared to other styles of isolation valves. There are three main types of butterfly valves: Resilient, High Performance (Double Off-Set) and Triple-Offset. Total Valve Systems can offer a butterfly valve to meet your needs either as manually operated or actuated.
Used primarily to prevent reverse flow through pipes, efficient double-door (or non-return) check valves play an especially important role in protecting pumps and compressors.
Also known as concentric or zero-offset valves, resilient-seated butterfly valves are widely favored for specialty liquid and gas applications.
Also known as high-performance butterfly valves, double-offset valves feature two offset stems that offer especially long life due to reduced contact between valve discs and seats.
For the most demanding applications in your drilling activities, triple-offset butterfly valves are essential for high pressures and high-temperature that require metal vs. soft seats.
The TRICENTRIC® Triple Offset is recognized in the market for excellent flow and control characteristics, sealing capabilities (zero leakage bidirectional, upon customer request) and dependability in a wide range of applications.
