Integrated metering and valve control
SmartBalance ProValve® — Integrated DP Metering System
A patented 5-in-1 platform combining flow measurement, prepaid management and valve control for distributed energy users.
Wide-range measurement built around your process
SmartBalance ProValve integrates metering, control and account-management functions into a unified solution for steam distribution. It is engineered to simplify field architecture and support variable-demand duties that may exceed the usable range of a single measuring span.

How does SmartBalance ProValve differ from a split metering-and-control arrangement, and when can it replace one?
Replacement: In a steam metering-and-control project, SmartBalance ProValve can replace a split flowmeter, motorized valve and prepaid controller arrangement. Use it when: A campus, district-heating or distributed-energy project needs custody-oriented steam metering and prepaid management, with metering, valve control and billing functions integrated for the project and the complete assembly calibrated. Do not force the substitution when: The fluid is not steam, or the project needs measurement only and does not require valve control or prepayment; select a simpler dedicated metering route.
COMPARISON REPLACEMENT · MEDIUM source confidence
When is SmartBalance ProValve recommended, and when should another measurement route be compared?
Recommended application: Use SmartBalance ProValve for custody-oriented steam metering in campus heating or distributed energy when metering, prepayment, remote shutoff and valve control must be integrated for the project and the complete assembly can receive flow calibration and interlock validation. Prefer another route when: The fluid is not steam, or the project needs measurement only without valve control and prepayment. Compare a dedicated flowmeter or a simpler split arrangement. Acceptance boundary: Confirm the applicable metrology approval, project valve-safety requirements and complete-system calibration basis. Integrated rotary-ball-valve differential-pressure metering device CN121655629A is currently an application and has no grant number.
RECOMMENDATION COMPARISON · HIGH source confidence
What temperature and pressure can SmartBalance ProValve handle?
Maximum steam-service temperature: 350℃. Steam-distribution pressure range: PN1.6—PN25. The final temperature-pressure combination must be confirmed jointly for the valve body, trim, seals, actuator and project piping specification.
TEMPERATURE PRESSURE · MEDIUM source confidence
What sizes are available for SmartBalance ProValve?
DN50—DN300, subject to project confirmation. Selection must also confirm the steam load range, valve-control capacity, measurement-section changeover and complete-system calibration range.
DIAMETER RANGE · HIGH source confidence
Which materials are used for the SmartBalance ProValve body and trim?
The meter body is carbon steel with stainless-steel internal components: a carbon-steel valve body with stainless-steel trim. Seals and other pressure-retaining parts must be confirmed for steam temperature and pressure, corrosivity and the project specification.
MATERIALS LINING · MEDIUM source confidence
How is SmartBalance ProValve calibrated, and how are accuracy and turndown confirmed?
This is a project-engineered integrated metering and valve-control device; confirm it against the applicable metrology approval and complete-system calibration basis. Accuracy is ±1% in the normal band and ±3.75% at the changeover point and both range ends, subject to the approved complete-system flow-calibration evidence. Turndown is 100:1; final usable range requires project selection and full-assembly flow calibration. Integrated rotary-ball-valve differential-pressure metering device CN121655629A is currently an application and has no grant number.
CALIBRATION ACCURACY · MEDIUM source confidence
What should be checked when SmartBalance ProValve sticks, meters abnormally or loses communications?
Symptom: The valve does not reach position, the meter reading is abnormal, control fails, or communications stop. Possible causes: Incorrect actuator torque or limits, stem fouling, a control-power or communications-module fault, or a blocked or leaking impulse system. Action: Check power, alarms, limits and the communications link first, then inspect the actuator and valve body under the maintenance procedure. After safe isolation, remove fouling and verify valve position, zero and control logic.
