Triple Duty Valve Manufacturer in USA
A triple duty valve is a compact, multifunctional valve used in pump discharge systems to combine flow balancing, non-return protection, and isolation in a single unit. By integrating these three critical functions, triple duty valves simplify piping layouts, reduce installation costs, and improve pump and system reliability.
SVR Global is a leading Triple Duty Valve Manufacturer and Supplier in USA, delivering engineered triple duty valve solutions for power plants, water infrastructure, HVAC systems, and industrial pumping applications. Our triple duty valves are designed to provide accurate balancing, reliable backflow prevention, and positive shut-off in both commercial and industrial service conditions.
With extensive experience supporting EPC contractors, consultants, and plant operators, SVR Global supplies triple duty valves that meet stringent project specifications and internationally recognized valve standards.
What Is a Triple Duty Valve?
A triple duty valve is a multifunctional valve installed on the discharge side of centrifugal pumps. It performs three essential functions within a single valve body:
- Flow regulation and hydraulic balancing
- Non-return (check valve) protection to prevent reverse flow
- Positive isolation of the pump for maintenance
By replacing multiple individual valves with one compact unit, triple duty valves enhance system efficiency while reducing space requirements and installation complexity.
Where Are Triple Duty Valves Used in Pumping Systems?
SVR Global triple duty valves are widely used in pump protection and flow control applications, including:
- Chilled water and HVAC pumping systems
- Power generation and utility pump stations
- Water supply and distribution networks
- Industrial process cooling systems
- Commercial and institutional building services
These applications require valves that ensure stable pump operation, prevent backflow, and allow safe and efficient system isolation.

Triple Duty Valve FAQs
What is a triple duty valve used for?
Triple duty valves are used on pump discharge lines to balance flow, prevent reverse flow, and isolate the pump.
Where is a triple duty valve installed?
It is typically installed immediately downstream of a centrifugal pump.
Can a triple duty valve replace multiple valves?
Yes. A triple duty valve replaces a balancing valve, check valve, and isolation valve within a single compact unit.
