Outstanding Pressure Control Under All Conditions

The 61.3 Control Butterfly Valve provides outstanding pressure control performance. With its fast and precise acting motion controller (0.1 s) it’s the perfect solution for fine control in CVD and ALD processes. The plate acts as a throttling element and varies the conductance of the valve opening. The integrated pressure controller of the 61.3 calculates the required plate position to achieve the set pressure as fast as possible.

It is especially designed for harsh downstream processes with particle in the gas stream. The 61.3 stays fully operational despite high particle loads and debris accumulation by design.

Already installed in thousands of demanding applications under various process conditions, the 61.3 series has proven its outstanding reliability. With a robust design and direct mounting option, as well as reduced and easy maintenance, the 61.3 series convinces in all aspects.

Various design options in body material, surface treatment, elastomers, flange connections, special sizes as well as special control algorithms (adaptive, fix PI down-stream/soft-pump) simplify the integration into various vacuum applications.

61.3 Control Butterfly Valves is available in aluminum or stainless steel, with standard flange connectors in ISO-KF and ISO-F. Customer-specific flanges can be integrated as well as special features like an integrated heater with insulation. Various FFKM/FKM elastomers are available on request (FKM is standard).
