Slurry valve
1/4" - 1 1/4", 100 psig | MV-20 series
Partek Division
Machined PTFE body for superior chemical resistance.
Machined modified PTFE diaphragm for excellent flexibility and long cycle life.
Fully swept open bowl diaphragm seat area for smooth flow transition.
Self draing design minimizes areas for entrapment and stagnation of media.
Angled and rounded internal flow path provides faster purging cleaning of valve.
