ORBIT VALVES

ORBIT Rising Stem Ball Valves

ORBIT Rising Stem Ball Valves

Built for Zero Leakage in 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 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.

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.

FE Type Testing Results

Special Features & Enhancements

ORBIT Low-E valves were submitted to ISO 15848-1 type testing and earned certification for their excellent, industry-leading performance results, achieving the best possible ISO 15848-1 tightness class rating of AH at the limits of the valve design temperature:
