Swagelok H22-BN3674-2O Hastelloy Normally Open Valve With VCR Ends

Swagelok H22-BN3674-2O is a Hastelloy bellows-sealed valve in Swagelok’s BN Series, configured with VCR end connections. The H22 designation identifies Hastelloy alloy construction, delivering corrosion resistance for aggressive fluids, while the BN family provides a compact, packless seal with all-metal sealing to atmosphere. This is a normally open valve, meaning it is open in its de-energized state, and it uses Swagelok VCR fittings for secure, leak-tight connections in high-purity or corrosive service. The BN3674-2O configuration specifies the exact porting and seal geometry for this part number, ensuring precise compatibility with matching Swagelok VCR fittings and system tubing.
