ORBIT VALVES
ORBIT VALVES
ORBIT Rising Stem Ball Valves
Delivering Zero Leakage, Low Torque Operation, and Long-Term Reliability for Critical Isolation Applications.
Ideal for applications that require zero leakage and frequent operation, ORBIT rising stem ball valves are used globally in critical isolation applications.
ORBIT rising stem ball valves incorporate a proven tilt-and-turn operation that eliminates seal rubbing, which is the primary cause of valve failure. The absence of seal rubbing during both opening and closing means easy, low-torque valve operation and long-term reliable performance.
When an ORBIT rising stem ball valve is closed, the core is mechanically wedged tightly against the seat, ensuring positive shutoff. When a valve begins to open, the core tilts away from the seat and line flow passes uniformly around the core face. This eliminates the localized high-velocity flow that typically creates uneven seat wear in ordinary ball, gate, and plug valves. The core then rotates to the fully open position.
ORBIT Actuation and Instrumentation
QRC provides tailored packages that include valves, actuators, and instrumentation. Our actuation and instrumentation services for ORBIT rising stem ball valves provide reliable, trouble-free on-off operation and are especially suitable for simple or extensive instrumentation.
ORBIT rising stem ball valves can be equipped with matched valve linear actuators, and many capabilities can be added to the basic double-acting actuator. Models are available with a spring-return option to open or close. Manual override mechanisms also are available.
A variety of instrumentation capabilities can be provided to meet a variety of your system’s needs. Many common systems are available as economical standard packages. Pneumatically or electrically activated systems also are available.
Orbit Valves
Unique tilt-and-turn design for fast, low-torque operation and long-term, reliable performance in applications when zero leakage and frequent operation are requirements.
Cameron’s ORBIT® valves are ideal for applications when there is need for zero leakage and frequent operation. They are used globally in gas processing plants using molecular sieve systems in switching service.
Orbit Automated Valve Packages
Cameron’s Orbit® brand can provide you with perfectly matched packages that include valves, actuators and instrumentation.
These valves are ideal for automation by the very nature of their operating principle. Many automated valves remain open or closed for extended periods of time. This and other environmental and process conditions can cause higher breakaway torque in valves with friction between their sealing surfaces.
