Domestic Water Use: Integrated check valve nipple (e.g. R189V) ensures compliance with potable water standards like ACS / KTW.
Leak-Detection Systems: FIG 530 models include calibrated expansion relief (e.g., 25 psi, 50 psi) to maintain system integrity.
Gas Regulator & Instrumentation: High-pressure nipple-check valves (e.g., CGA-346/510) rated up to 3000 psi for air, acetylene, propane, and natural gas.

Functionality: Acts as a one-way check valve to prevent backflow in domestic water circuits or instrumentation systems. Common applications include potable water systems, tank overfill protection, HVAC units, and gas line regulators.
Construction:
- Body Material: High-quality brass (e.g., CW617N), providing corrosion resistance for potable water use. Internal Components: Durable spring and poppet assemblies—standard versions are brass/plastic; leak-detection models use stainless-steel springs and FKM/Viton O‑rings.
Performance Specifications:
- Maximum Working Pressure: Typically up to 10 bar (150 psi) for potable-use models; specialized versions support up to ~3000 psi (gas service). Temperature Range: Rated up to 90 °C for water service; gas/instrument versions support higher pressures and varied temperatures.
Flow Rating: Typical Kv ≈ 5.1 m³/h for ¾″ size units.
Connection Types: Available in standard male threaded nipples — ¼″, ½″, ¾″, 1″, with lengths from ~3 cm (1¼″) to longer.
