LIAG® 2-Way Control Arc Valves

LAUFER 2-Way Control Arc Valves are designed for precise flow control in hygienic processing applications. With a smooth flow path and favorable flow characteristics, these valves are ideal for proportioning viscous or pasty products and sensitive media that may contain solid particles.

Engineered to meet 3-A and FDA standards, the valves ensure hygienic, product-saving performance while maintaining full cleanability. Depending on the process requirements, they can be supplied with different shutter qualities and linearization inserts to optimize flow control. Operation is managed via a standard 4–20 mA (0–10 V) electro-pneumatic actuator, allowing for accurate, repeatable adjustments.
