Cryogenic
Ball valves open and close with a quarter-turn function, using a handle or gearbox and are commonly used in the exploration, production, gas utility, chemical and industrial sectors. Ofserv is one of the largest suppliers of API 6D ball valves to the transmission, pipeline gas gathering, tank farm storage, and utility sectors. Ofserv also stocks extensive size ranges, multiple configurations and most body and trim types of floating and trunnion ball valves. Both Floating ball valves and trunnion ball valves are offered in full and reduced bore sizes.

High Performance
Butterfly valves typically have a circular shaped disc that rotates to open or close the valve, thus controlling the flow of material through the valve, with a quarter-turn function, using a handle or gearbox. Ofserv maintains an extensive inventory of resilient seated butterfly valves, high performance butterfly valves, and triple offset butterfly valves to service all major industrial sectors. Our inventory includes butterfly valves in carbon steel, stainless steel and alloy materials.

Ofserv's partner is a leading distributor of plug valves to the energy and industrial markets. Plug valves are named for the cone-shaped, plug-like device that controls the flow of fluid through the valve. Rotating the handle a quarter turn or turning the handwheel on the gearbox starts or stops the flow of fluid by introducing the through bore or solid portion of the plug. The plug valve is ideal for gas transmission, gas utility and chemical applications, and is offered and stocked in elastomeric lined or full metal construction.

API6A / API6D
A check valve design only allows fluid to flow one direction. It is generally used in conjunction with other types of valves and will close automatically when line pressure is lost, thus it has no handle to turn on and off. This feature makes check valves ideal for preventing plant and equipment damage caused by excess backflow, a necessity across all streams of the energy industry. Check valves are stocked in several body configurations and materials.

Gate
Multi-Turn valves are opened and closed by turning a wheel more than 360 degrees. Two primary examples of this type of valve are the gate valve and globe valve. To open and close the gate valve, multiple turns of the handle are required to turn an acme threaded nut on the threaded shaft of the valve causing it to open or close by raising or lowering the gate. These valves operate in one of two positions, open or closed, and are not recommended for throttling. The globe valve, on the other hand, opens and closes incrementally and is used to modulate flow levels, pressures, or temperatures. Both the gate valve and globe valve are commonly used in downstream applications. Ofserv maintains large inventories of gate valves and globe valves in materials such as carbon steel, stainless steel and special alloys to serve the needs of the refining, petrochemical, chemical and process industries.

Ball
The subsea environment is one of the toughest that a valve can face. Subsea valves must be completely reliable while often exposed to corrosive and hazardous fluids and high pressures. Ofserv provides a wide range of subsea valves specifically designed to meet these challenges. Ofserv stocks an extensive and broad inventory of subsea ball valves, gate valves, choke valves and check valves manufactured by the world’s top manufacturers.
