Select the system
Match the valve technology to the pipe material, diameter, pressure, condition, orientation, and owner requirements.
Add permanent control
Valve Insertion
Install a permanent valve on an active water main with minimal service interruption and a focused excavation footprint.
4–24Inch nominal size range available across qualified valve systems
01Job-specific technical review before field mobilization
24/7Direct response path for qualified emergency needs
100+Years of equipment, fitting, and field experience
Method in context
Control the work. Protect continuity.
Koppl evaluates and installs pressure-rated insertion-valve systems for existing water infrastructure. The selected method is matched to pipe material, diameter, condition, pressure, access, and the control point the owner needs.
Where the method creates value
- Add a permanent control point while the main remains in service
- Limit the work to one primary excavation for many applications
- Reduce draining, chlorination, and customer disruption
- Select among qualified valve technologies for the specific line
Common applications
- Municipal water
- Transmission and distribution
- Wastewater force mains
- Industrial water
- Valve replacement planning
- Future maintenance control
The technical-review boundary
Published sizes, pressures, temperatures, and equipment capabilities describe potential operating ranges, not automatic approval for a specific project. Final feasibility depends on verified line data, field condition, system configuration, media, procedures, and the selected equipment.
Typical project sequence
A field plan with visible control points.
The exact method changes by application. These four stages show the decision structure that keeps engineering, equipment, field work, and completion connected.
Prepare the site
Confirm excavation, support, access, line location, and the field controls required for the installation.
Install under pressure
Mount and test the assembly, create the controlled opening, and install the valve components under the approved method.
Commission control
Operate and verify the new valve, complete the installation, and document the permanent control point.
Safety + validation
Method before mobilization.
A usable plan connects the actual line data to equipment selection, fitting design, access, testing, operating limits, PPE, work-zone controls, and the final return-to-service sequence.

Service questions
Useful answers before the call.
These answers frame the method. A project-specific answer starts with the actual line and site conditions.
Browse all FAQs01Can an insertion valve be installed with water flowing?
Qualified insertion-valve systems are designed for installation on an active line, allowing the owner to add control with little or no broad service interruption.
02Which pipe materials can be considered?
Available systems can support common materials including cast iron, ductile iron, steel, PVC, and asbestos-cement pipe. The exact valve system and limits require technical review.
03Which valve brands does Koppl support?
Koppl offers systems from Hydra-Stop, Advanced Valve Technologies, and Mueller. The right system depends on the pipe and project requirements.
Related capabilities
The final method may combine services.
Live-line projects often connect tapping, temporary isolation, permanent control, fabrication, or repair into one coordinated sequence.
Hot Tapping
Add a branch connection to an operating pipeline and maintain service across the wider system.
Explore capabilityLine Stopping
Temporarily isolate a section of active pipe so modifications or repairs can move forward with less system-wide disruption.
Explore capabilityPipe Freezing
Create a monitored ice plug for targeted work where draining or a broader shutdown is impractical.
