Transfer valve/insert MONOVAT Technical data Leak rate1) at body and at seat in mbar Is-1 At room temperature (25°C) and under clean environmental conditions. Maximum values: depending on operating conditions and sealing materials In order to maximize the life time of the gate; the operating pressure should be kept as low as possible, however high enough to ensure the required leak rate in the closed valve position. Depending on the length of the sealing line (size of gate), tolerances of the sealing lip, accuracy of the measurement and required leak rate, the ope- rating pressure settings...
