Wafer type butterfly valve, type 1320/1321

This wafer PTFE seated butterfly valve is designed for applications where standard elastomers are not suitable anymore such as in the chemical, pharmaceutical or in the food industry. The body has a two piece body design with a silicon or a viton backing. An option is to use a 3mm PTFE coated disc (type 1321) instead of the standard stainless steel disc (type 1320).
