APTech AP4650SM 2PW FV6 FV6 Manual Diaphragm Valve

APTech AP4650SM 2PW FV6 FV6 is a stainless-steel, manually operated diaphragm valve engineered for precise gas handling in vacuum and high-purity systems. The body is SS 316L (secondary remelt) with an electropolished and passivated finish, housing a Ni‑Co diaphragm (UNS R30003) and a PCTFE seat for tight, chemically resistant sealing. It features two welded ports (2PW) and two 1-inch ports, with FV6 indicating 3/8-inch face-seal female connections on both ends and a surface finish of Ra max 10 µin. An optional indicating switch (ISH3) can be paired for status monitoring. This valve belongs to the AP4650 family and is commonly employed in vacuum technology and gas-handling applications where reliable metal diaphragms and robust shutoff are required at pressures up to 250 psi.
