..Compression Valves ..PTFE Screw-locking
| |  | These valves make possible the assembly of a wide range of pipeline systems. They are chemically inert and operate over a wide temperature range. Wetted parts are pure PTFE; lock nuts are polypropylene and compression seals are VITON.
Valves with screw locking are for use with rigid or semi-rigid: GLASS, PTFE or FEP tubing to withstand vacuum of 10¨©ömm Hg and pressure of 4 Bar. Valves are not recommended for use in applications where rapid temperature changes of 20° to 30°C occur. | |  |  |  |
