Construction Details
The valve features a lead-free brass body with a CTS connection on one end and a meter-nut connection on the opposite end.
The CTS side connects to compatible Copper Tube Size water-service tubing, while the meter-nut end is designed to connect to a compatible water meter or meter-setting component.
An internal rotating ball controls water flow through the valve. Quarter-turn operation moves the ball between the fully open and closed positions for quick service-line isolation.
Connection Configuration
CTS Connection
The Copper Tube Size connection is designed for compatible water-service tubing used in residential, commercial, municipal, and utility installations.
Meter Nut Connection
The meter-nut end provides a removable connection to a compatible water meter or meter-setting component for service and maintenance access.
How the Curb Stop Ball Valve Works
Open Position
When the opening through the internal ball is aligned with the valve body, water can flow through the valve and meter connection.
Closed Position
Rotating the operating mechanism approximately 90 degrees moves the solid portion of the ball across the flow path to isolate the service line.
CTS to Meter Nut Transition
The CTS x meter nut configuration combines a service-line shutoff valve and meter connection into one compact assembly.
This configuration can simplify meter installations by reducing the number of separate adapters required between CTS water-service tubing and the compatible meter connection.
Lead-Free Brass Construction
Lead-free brass is commonly selected for compatible potable-water and water-service installations where applicable lead-content requirements must be met.
Confirm the selected curb stop meets applicable plumbing codes, utility requirements, certifications, pressure ratings, temperature limits, and local installation requirements for the specific system.
Curb Stop at the Meter Connection
Installing a curb stop at or near the meter connection provides an isolation point that can help simplify meter service, maintenance, replacement, and water-line repairs.
The meter-nut connection can allow the meter assembly to be disconnected while the curb stop remains installed on the service line, subject to the requirements of the specific installation.

Selecting the Correct Curb Stop Ball Valve
| Selection Point | What to Confirm |
|---|---|
| Valve Size | Confirm the valve size matches the service-line and meter requirements. |
| CTS Connection | Verify the CTS end matches the tubing used in the water-service installation. |
| Meter Connection | Confirm the meter nut is compatible with the water meter or meter-setting component being connected. |
| Lead-Free Requirement | Verify lead-free construction is appropriate for the intended water-service application. |
| Operating Conditions | Confirm pressure, temperature, plumbing-code, utility, and complete system requirements before installation. |
Installation & Selection Considerations
- Confirm the valve size, CTS tubing size, and meter-nut compatibility before ordering.
- Verify the meter connection matches the intended meter or meter-setting assembly.
- Inspect all sealing surfaces and connection components before installation.
- Install the valve so the operating mechanism remains accessible for service and shutoff operation.
- Verify applicable lead-free, pressure, temperature, plumbing-code, utility, and local installation requirements before use.

What is a Lead-Free Curb Stop Ball Valve - CTS to Meter Nut?
It is a quarter-turn water-service shutoff valve with a Copper Tube Size connection on one end and a meter-nut connection on the other.
What does CTS mean?
CTS means Copper Tube Size and identifies the tubing connection used on the water-service side of the valve.
What is the meter nut used for?
The meter nut provides a removable connection between the curb stop valve and a compatible water meter or meter-setting component.
Why use a CTS x meter nut curb stop?
It combines water-line shutoff and the transition from CTS service tubing to a compatible meter connection in one fitting.
How does the ball valve operate?
The internal ball rotates approximately 90 degrees between open and closed positions, providing quarter-turn shutoff operation.
Where is this style of valve commonly installed?
It is commonly used in compatible water meter and service-line assemblies where CTS tubing connects to a meter and a shutoff point is required.
Why is lead-free brass important?
Lead-free brass is commonly specified in potable-water installations where applicable lead-content requirements must be met.
What should I confirm before ordering?
Confirm the valve size, CTS tubing compatibility, meter-nut connection, meter requirements, lead-free requirements, pressure, temperature, and applicable water-service installation requirements.
Important Ordering & Installation Notes
- Lead-free brass curb stop ball valve.
- Connection configuration is CTS x meter nut.
- Confirm both CTS tubing size and meter-nut compatibility before ordering.
- Verify meter connection dimensions and sealing requirements before installation.
- Verify lead-free, pressure, temperature, plumbing-code, utility, and application requirements before use.
