Check Valve 3/8″ ODS 3132W/3 Castel

The Castel 3132W/3 check valve is used in HVAC and refrigeration systems to control the direction of refrigerant flow. It automatically allows flow in one direction and blocks reverse circulation, reducing the risk of pressure imbalance and equipment damage.

In smaller-capacity refrigeration lines, stable flow control is just as important as in large systems. This valve supports efficient operation and long-term reliability. Its durable brass construction and 3/8″ ODS connection make it suitable for professional installations.
