Valves / Pressure reducers

Self-acting diaphragm-actuated pressure reducing valve that controls the outlet pressure. No auxiliary power needed.

This reducer model is suitable for working with steam, compressed air and non-hazardous gases and liquids.

Fast and effective response to a change in demand.
