Understanding the Role of 15mm Check Valve with Isolator

Modern fluid control systems increasingly rely on 15mm check valves with isolators to prevent reverse flow while enabling maintenance without system shutdown. These dual-function components combine a 15mm swing check valve's mechanical efficiency with isolation gate functionality, reducing installation footprint by 40% compared to separate valve assemblies.

Technical Specifications & Performance Metrics

Engineered for pressures up to 25 bar and temperatures ranging from -20°C to 120°C, high-grade 15mm check valves achieve:

Flow rates of 1.8-2.4 m³/h at 3 bar differential pressure
Leakage rates below 0.01% under ANSI/FCI 70-2 Class VI standards
Cycle durability exceeding 500,000 operations

FAQS on 15mm check valve with isolator

Q: What is a 15mm check valve with isolator used for?

A: A 15mm check valve with isolator prevents backflow in piping systems while allowing manual flow isolation. The isolator lets you shut off water or fluid without disrupting the entire system, making maintenance easier. It’s ideal for residential and commercial plumbing applications.

Q: How does a 15mm check valve differ from a 15mm check valve with isolator?

A: A standard 15mm check valve only stops reverse flow, while the 15mm check valve with isolator adds a manual shut-off feature. The isolator provides better control during repairs or replacements. This dual functionality enhances system flexibility and safety.

Q: Can a 15mm swing check valve be used with an isolator?

A: Yes, a 15mm swing check valve can be paired with a separate isolator valve for flow control. However, integrated 15mm check valves with built-in isolators offer a compact, space-saving solution. Always verify compatibility based on pressure and temperature requirements.

Q: How to maintain a 15mm check valve with isolator?

A: Regularly inspect the valve for debris or mineral buildup that could hinder movement. Use the isolator to shut off flow before cleaning or replacing internal components. Follow manufacturer guidelines for disassembly to avoid damaging seals or hinges.

Q: What applications suit a 15mm swing check valve?

A: A 15mm swing check valve is ideal for horizontal or vertical pipelines requiring low-resistance flow control. Its swinging disc design ensures quick closure to prevent backflow. Common uses include water supply systems, heating systems, and industrial fluid handling.
