Mixproof Valves (pig-able), type L are based on the VARIVENT® valve, type T. A special feature of this valve is that one of the valve housings may be pushed out using a pig. This technique allows for the recovery of high quality products at the end of a process step and thus to minimise product residues inside the pipe.
Mixproof Valves (pig-able), type L meet the 3A standard.
