The valve is to have Fail-Dry Safety Design, which incorporates a vented chamber between the PTFE bellows and the secondary elastomer diaphragm backup seal. The vented chamber has a 1/8" NPT port so that thermoplastic tubing, if desired, can be piped to a remote safe location in the event of concern with leakage of dangerous liquids or vapors.
