Application-Specific Variants

• 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.
