ORBIT VALVE’S rising stem ball’s unique tilt-and-turn design reduces seal rubbing and delivers reliable performance. It is the proven technology for arduous process conditions, including high-temperature, critical isolation to molecular sieve switching services. This legacy of innovation began in 1912, when Alfred Heggem founded The Oilwell Improvements Company of Tulsa. Heggem’s groundbreaking ball valve seating principle, patented in 1935, was considered by many at the time to be the first major advancement for valves in half a century. This patent is the forerunner to all ball valves today.

Nearly 80 years later, the same engineering technology still is used to safeguard against seat rubbing—a leading factor for why ORBIT valves are world-renowned for high integrity and long service life.
