Key Specifications / Parameters Product Series: CSB400 Series Pressure Reducing Regulators Model: CSB424‑IN Operating Principle: Direct‑acting, spring‑loaded regulator Body Sizes & End Connections: Multiple options including NPT, Rp (gas thread), ANSI flanged (CL 125 FF / CL 150 FF), PN‑rated, depending on model build Maximum Operating Inlet Pressure: Up to ~16 bar (232 psig) for certain builds; emergency rating ~20 bar (290 psig) for some builds Outlet Pressure Range (typical): From ~17 mbar (≈6.8 in w.c.) up to ~3.0 bar (≈43.5 psig) for standard models Operating Temperature Range: Standard −20 °C to +66 °C (−4 °F to +150 °F); Some low‐temperature versions go down to −30 °C (−22 °F) Materials: Bodies available in ductile cast iron and WCC steel; other internals include various alloys and elastomers depending on service Pressure Registration Options: Internal, external or dual registration of downstream pressure; variants include integrated monitor or slam‑shut modules for overpressure protection Typical Applications: Gas pressure reducing stations, commercial/industrial gas service, where stable downstream pressure and safety is required
