Is suitable for through flange valve sealing pressure and valve body intensity pressure performance test.

When installing a pinch valve to a rubber, PVC, or any "slick" mating flange, we recommend that you install a metal serrated gasket between the two flanges to assist in the seal.

For ease of installation, insert all flange bolts through the valve flange and then through the sleeve flange, but do not let the bolts extend beyond the surface of the flange rubber (See Figure 4).
