Water Meter Ball Valve Controller Actuator

What the Ball Valve Actuator Actually Solves for Buyers

Most smart-meter ball valve failures do not come from the motor. They come from thrust falling short on aged valves, current draw draining the battery pack faster than expected, or wiring that does not match the meter board. This actuator addresses those three failure points directly.

• Thrust with headroom for aged ball valves.Rated at >15 kg through a 1000:1 gear reduction, the actuator is sized for small-bore water-meter ball valves. Confirm the valve seating torque during technical review.
• Low current draw for battery-powered meters.Operating current is ≤25 mA at 3.6V nominal, with a locked-rotor current of 450 mA. The low operating current allows the actuator to run from a dry-cell pack without excessive drain, while the locked-rotor figure tells your driver circuit what to expect during valve seating.
• Five-wire control matched to meter boards.Red positive, black negative, blue open, white COM, yellow close. The wiring scheme separates power from open/close control signals, so the actuator can be driven by the meter board's existing control logic.
• Designed for non-electrified meter pits.The actuator is intended for residential, underground, and non-electrified installation scenarios where running 220V mains or dedicated power cables is impractical.

Technical Specifications Buyers Should Verify Before Ordering

The table below reflects the standard ball valve actuator configuration. Where your meter platform operates on a different voltage, thrust curve, or wiring convention, these parameters can be customized during the OEM review.

If your meter board supplies a different control signal polarity or uses a different connector, Kaiye’s engineering team can review the wiring and propose a matched configuration rather than forcing a standard harness into an incompatible meter platform.

Integration, Wiring, and Mounting: What Engineers Ask First

For OEM buyers, the actuator is only as good as its fit with the meter housing, ball valve stem, and control board. This actuator uses a compact outline intended for space-constrained smart-meter enclosures, with a wiring scheme that separates power from the open/close control signals.

Power wiring.Red is positive, black is negative. The drive circuit should be sized for the locked-rotor current of 450 mA, even if normal operating current is ≤25 mA, because valve seating can briefly demand higher current. Reverse-polarity protection on the meter board is recommended if the actuator is field-replaceable.

Control wiring.Blue is open, white is COM, yellow is close. This circuit should be treated as a control input, not a power line, and should remain independent of the communication module so that a communication failure does not disable valve control.

Mounting interface.The actuator is designed around the ball valve stem and mounting pattern used on small-bore smart-meter valve bodies. Before volume release, buyers should confirm stem square, mounting hole spacing, and actuator orientation inside the meter housing. Kaiye can supply a sample for mechanical fit-check before the production order is placed.

If you are also sourcing the meter housing or the complete valve assembly, the actuator can be reviewed together with the water meter shell and valve body to reduce interface mismatch at assembly.

Where the Ball Valve Actuator Is Used: Application Fit for Volume Projects

The actuator is positioned for small-bore ball valve control where battery-powered operation and low current draw matter more than high-speed actuation. Typical volume applications include:

Because the actuator is part of Kaiye’s broader water-meter component platform, buyers sourcing multiple components can consolidate qualification and logistics. If your project also requires wireless communication at the meter level, the actuator is designed to work alongside Kaiye’s wireless water meter platform.

Quality, Consistency, and What “Manufacturer” Actually Means Here

For B2B buyers, “manufacturer” should mean process control, not just a trading company with a catalog. Kaiye operates an ISO 9001 quality system, runs automated production for actuator assemblies, and has been producing water-meter actuators for more than two decades. This ball valve actuator benefits from that production base in three concrete ways:

Batch consistency.Gears are machined to controlled dimensions. Automated assembly reduces unit-to-unit variation in gear mesh, thrust output, and response time—critical when you are installing thousands of actuators across a utility project.

Incoming inspection and final test.Standard production includes functional checks for current draw, response time, and valve travel. Buyers can request the inspection protocol and sampling plan before placing a volume order.

Traceability.Model code, production batch, and test records are retained so that if a field issue appears, the affected population can be isolated rather than treating every actuator in the project as suspect.

OEM Customization and Procurement Terms

The ball valve actuator is available as a standard unit, but standard does not mean fixed. For OEM and project buyers, the following items are commonly customized after technical review:

Cable and connector.Cable length, wire gauge, color code, and connector type can be specified to match your meter housing and assembly fixture.

Control logic.Open/close signal polarity and COM configuration can be aligned with your meter board.

Thrust and gear ratio.For valves with higher seating thrust or different stem geometry, an alternative gear ratio or motor tier may be more appropriate than the standard 1000:1 configuration.

Branding and packaging.Private-label marking, neutral packaging, and project-specific labeling are available for volume orders.

Typical MOQ and lead time are confirmed at quotation. Standard delivery is generally 15–30 days after PO and sample confirmation, depending on order quantity and component availability.

Procurement FAQ

Are you a manufacturer?
Yes. Kaiye has its own factory with more than 30 years of production experience.

Can you pack this product with our requirements?
Yes. Customized packaging and labeling are welcome for volume orders.

What is the delivery time for regular orders?
Delivery time is generally 15–30 days, and can be shorter or longer based on model period and order quantity.

What is the wiring definition?
Red is positive, black is negative, blue is open, white is COM, and yellow is close.

What is the waterproof rating?
The standard configuration does not specify an IP rating. Confirm the required IP level with engineering for outdoor or submerged installations.

Is it compatible with 3.6V dry-cell battery smart water meters?
Yes. The actuator is designed for 3.6V DC systems with an operable voltage range of 2.5–5V. Confirm the meter board control logic and valve load during technical review.
