Bettis Multiport Valve Actuator (MPA)
The Bettis™ Multiport Valve Actuator (MPA) by Emerson is a high-precision pneumatic or hydraulic actuator designed for reliable, accurate control of multiport valves in complex flow systems such as sampling, blending, and fluid distribution.
The Bettis™ Multiport Valve Actuator (MPA), engineered by Emerson, is a precision-designed valve automation solution developed to provide reliable, efficient, and accurate operation of multiport valves used in complex flow control systems. The MPA is ideal for applications that require multi-position or sequential valve operation, such as sampling, blending, or multi-line fluid distribution processes in the oil and gas, petrochemical, and industrial sectors. Built on Bettis’ legacy of innovation and rugged reliability, the MPA system combines pneumatic or hydraulic actuation with precise mechanical indexing, enabling exact alignment of valve ports for safe and repeatable flow control. The actuator is engineered to handle multi-port ball or plug valves that require controlled rotation beyond 90°—including 120°, 180°, 270°, or 360° operation. Each MPA unit features robust construction, corrosion-resistant materials, and a compact design, making it suitable for both onshore and offshore environments. Its modular configuration allows for easy customization of port configurations, torque output, and control options, supporting both manual and automated control systems.

Feature of Bettis Multiport Valve Actuator (MPA)
- Designed for control of multi-port flowselectors (MPFS) with 3 to 8 ports typicaly in oil & gas industry for well production testing. Often combined with Multiport Flow Selector (MPFS).
- Allows diversion of fluids from a single flow line to a test outlet or sampling device
- I/O and alarm monitoring include – integral circuit breaker/disconnect, motor overload and motor thermal, loss of control voltage, encoder failure, stall detection and alarms (detects mechanical faults), 3-phase monitoring and phase correction.
- Solid-state motor starter and control software provides precise positioning of flow selector within +1 degree of selected port.
- High performance microcontroller updates motor control output every 4ms for precision motor control
- Remote display module (RDM) option available. RDM displays identical information and performs identical control as LDM. Allows for remote control up to 4,000 feet.
- Wide range of 4-pole motors available for any voltage or torque. Configurable for MPFS from 3 to 8 ports.
- 12-bit magnetic encoder coupled directly to valve stem for position feedback.
