1. Product Title

HZ‑BV‑SS1/2‑0.4s – Stainless‑Steel Piston‑Type Flow Switch

2. Product Overview

The HZ‑BV‑SS1/2‑0.4s is a stainless‑steel piston‑actuated flow switch for pipeline liquid‑flow monitoring. With G1/2’’ process connection and factory‑set switching threshold at 0.4 l/s, it triggers dry‑contact switch output when liquid flow exceeds or drops below set flow rate. All wetted components are stainless‑steel material, suitable for water, oil and many non‑corrosive industrial fluids. Installed inline on process pipelines, this device provides flow‑loss alarm protection to prevent pump dry‑run or cooling‑loop flow‑failure damage to process equipment.
