Product Overview
DURAN® patent valves complete with PTFE patent valve plugs are two-way valves, which are frequently used for the construction of steering lines (vacuum inert gas lines, nitrogen distribution rakes) and enable grease-free operation. The tap plug is secured in the tap sleeve by a three-part retaining device.

We recommend the use of PRODURAN® valves for particularly high leakage rate requirements.
