Description
1/4" PTFE Solenoid Valve for Concentrated Acids & Alkalis – CS Fluid Power SVC202
A compact, direct-acting 2/2 way normally closed PTFE solenoid valve designed for highly corrosive chemical applications. Featuring a full PTFE body and PTFE isolating diaphragm, the SVC202 Series is ideally suited to concentrated acids, alkalis and aggressive chemical media where conventional brass or stainless steel valves are unsuitable.
Suitable for hydrochloric acid (HCl), sulphuric acid (H₂SO₄), chemical dosing systems, laboratory equipment and corrosive process applications.
