PRD Proportional Pressure Reducing
Armaş “PRD” model proportional pressure reducing control valves reduce high upstream pressure values and downstream pressure values at a rate of 1/3. Proportional pressure reducing control valves reduces the downstream pressure at about 1/3 without affecting from flow rate and upstream pressure values. When there is no flow in the system, valve closes itself drip-tight. Proportional pressure reducing control valves do not equalize the upstream pressure value to the downstream pressure value. The valves should be placed in series in the pipeline, otherwise the system will not be balanced. If required, pilot valves can be added to proportional pressure reducers to change them easily to regulation valves.
