Excellent Sealing Performance with Web/Foil Protection

The 02.7 Roll-to-Roll Transfer Valve MONOVAT has been developed to meet the special requirements of continues web/foil coating processes. To ensure reliable sealing of the process chamber in line with protecting the web/foil band in continues coating processes the 02.7 is using a sophisticated roll-to-roll sealing system. The sealing system is based on VAT’s proven MONOVAT sealing technology. With the double sealing roll-to-roll design the sealing pressure is perfectly balanced between effective sealing and not damaging the web/foils. An intermediate pumping stage between both seals adds to the sealing performance.

Designed for high cycle production systems the 02.7 combines an outstanding fast motion time (≤ 1.5 s) with resistance against process-related deposits that would limit standard valve performance.

The special MONOVAT sealing technology used by the 02.7 allows a shock-free opening and closing movement of the gate minimizing particle activation and reducing seal wear. Furthermore, the for a double sealing system very compact design of the sealing mechanism also makes the whole valve very compact providing small mounting dimensions.

Operating already in hundredths web/foil production systems around the world under various process conditions, the 02.7 series has proven its outstanding performance in all aspects.
