Water Mete Valve Core Assembly

Project Type
Real customer project, already running at site

Industry
Water meter manufacturing

Region
South America

Application
Valve core assembly for water meters with integrated shut-off valve

Core Value
Reduce manual assembly steps and improve process consistency

This 10-station rotary assembly machine was designed for stable water meter valve core assembly. With a published cycle time of 5.5 seconds per piece, the theoretical output reaches approximately 654 pieces per hour. Under an 85% operating efficiency reference, the machine can support approximately 4,450 pieces per 8-hour shift, or more than 1.1 million pieces per year based on one 8-hour shift and 250 working days.

The machine footprint is approximately 2.0 sqm, making it suitable for manufacturers that need higher output within a compact production area.

From Manual Assembly to Controlled Rotary Process

Before automation, the valve core assembly process required several repetitive manual actions, including small-part handling, internal component placement, connector assembly, checking, transfer and unloading. In this project, 8 core process functions were consolidated into one rotary assembly cell.

The operator mainly handles product loading and production supervision, while feeding, positioning, insertion, press-fitting or tightening, detection and unloading are completed by the machine. This helps the customer reduce labor dependency and make the assembly process more standardized.

This project was developed for a water meter manufacturer in South America. The equipment is used for automatic assembly of valve core components in a water meter with an integrated shut-off valve structure.

The original process required multiple manual assembly steps for small internal parts, sealing components and brass valve-related parts. To improve production efficiency and make the process more controllable, the customer required a customized assembly machine that could integrate feeding, positioning, insertion, press-fitting, tightening, inspection and unloading into one compact system.

After installation and commissioning at the customer site, the machine was put into production and helped reduce a large number of repetitive manual operations.

Water meters with integrated shut-off valve functions have more complex internal structures than conventional water meters. The assembly process may involve a housing, brass connector, O-rings, washers, valve stem and spherical valve component. These parts must be assembled in the correct sequence with stable positioning and controlled force.

In manual or semi-automatic production, manufacturers often face inconsistent assembly quality, missing small parts, unstable operator rhythm and difficulty in standardizing process control. These problems become more obvious when production volume increases or when the product structure includes valve-related internal components.

Assembly Parts

Project Requirements

Water meter housing

Reduce manual assembly steps

Brass connector

Ensure stable positioning during indexing

O-ring

Automatically feed small components

Washer

Perform insertion, press-fitting or tightening

Valve stem

Detect material presence and in-position status

Spherical component

Allow future integration with other water meter production modules

The solution adopts a rotary multi-station indexing platform. The water meter housing is manually loaded into a dedicated fixture at the loading station. The rotary table then transfers the product step by step through each assembly station.

Each station performs a defined task, such as small-part feeding, O-ring or washer placement, internal component assembly, brass connector assembly, press-fitting, tightening, detection and automatic unloading. Multiple products can be processed at the same time at different stations, which improves efficiency while keeping the machine footprint compact.

The machine was designed around the customer’s product structure and process sequence. This ensures stable product positioning and repeatable assembly quality during batch production.

The assembly process is configured according to the water meter valve core structure. A typical process flow includes manual housing loading, automatic small-part feeding, O-ring and washer placement, valve stem and spherical component assembly, brass connector assembly, press-fitting or tightening, inline detection and automatic unloading.

The exact station sequence can be adjusted according to product drawings and sample parts. The key principle is to assign one clear function to each station and use rotary indexing to keep the whole process stable and repeatable.

This machine is already operating at the customer site in South America. By replacing multiple manual assembly actions with an integrated rotary assembly process, the customer reduced repetitive labor involvement and made the production process more structured and controllable.

From a capacity perspective, the 5.5 s/piece cycle time gives a theoretical output of approximately 654 pieces per hour. Under an 85% operating-efficiency reference, the estimated output is approximately 4,450 pieces per 8-hour shift, or more than 1.1 million pieces per year based on one shift and 250 working days.

The value of this project is not only higher efficiency. More importantly, the machine standardizes the assembly sequence, improves part positioning consistency, reduces the risk of missing small parts and provides a scalable foundation for future water meter production line automation.

The valve core assembly machine can work as a standalone production cell or be integrated with other water meter production modules. According to customer requirements, it can be connected with water meter dial installation, water meter core installation, laser marking and packaging systems.

This allows manufacturers to start with one key assembly process and gradually build a more complete automated production line according to production volume, factory layout and future expansion plans.
