Olab 33100‑TS‑11‑D Check Valve 2 1/8" Copper Pipe‑Weld Flanged Type

The Olab 33100‑TS‑11‑D Check Valve is a 2 1/8‑inch (≈55 mm) nominal size valve with copper pipe‑weld (B‑B) and flanged connections. Its body is cast from high‑purity OFHC copper, delivering 390 W/m·K thermal conductivity and excellent corrosion resistance. A spring‑loaded disc opens freely with forward flow and snaps shut against reverse flow, guaranteeing a 99.9 % back‑flow prevention rate. Pressure drop is low (ΔP ≤ 0.15 bar at 100 L/min), making it perfect for HVAC‑R, cooling water loops, heat‑recovery systems, and low‑pressure water/antifreeze circuits, where energy efficiency is critical. The flanged design enables quick installation and easy maintenance, while the valve tolerates temperatures up to 200 °C and operates safely from 0 to 1.6 bar. Certified to CE, ISO 9001 and RoHS standards, it meets global quality requirements. This valve offers long service life, reliable performance, and minimal maintenance cost for engineers seeking a robust flow‑control solution.
