Diaphragm Seals

Zavoda Diaphragm Seals are available in two basic sizes, Series 5 (small) and Series 6 (large). The difference between the two series is that the effective diaphragm area used in the 6 series is double that of the effective diaphragm area used in the 5 series. Therefore, the series 6 should be the choice for all sensitive and low pressure applications.
