5 years after Oklahoma became a state, The Oil Well Improvements Company was established by Alf G. Heggem in 1912 o manufacture and sell oil well supplies and machinery. His groundbreaking ball valve seating principle, patented in 1935, was considered to be the first major advancement for valves in half a century. Nearly 80 years later, the same engineering technology is still used to safeguard against seat rubbing – a leading factor for why ORBIT valves today are world-renown for high integrity and long service life. Today, ORBIT valves are used in over 88% of gas processing plants using molecular sieve systems in switching service, and 85% of LNG facilities worldwide. ORBIT valves are also in service in Exploration, Gathering, Production, Transportation and Process applications.
Quick (stock) delivery possible for a selection of Orbit valves
Orbit Rising stem ball valves for applications that require zero leakage and frequent operation.
Specifics to design
- tilt & turn operation that eliminates seal rubbing (the primary cause of valve failure) results in long term reliable performance.
- mechanical shutoff (independent of line pressure)
- uniform flow around the core (“ball”) so no uneven (local) seat wear due to high velocity flow.
- top entry
- self cleaning
- piggable
