proportional pressure reducing control valve a 3- way selector valve b In-line Finger Filter c Plug description 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 hermetically. 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. installation • Clean the pipeline before installing the valve. • Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • Ensure enough space around the valve assembly for future maintenance and adjustments. • While connecting valve on pipeline, place gasket between valve flange and pipe flange to ensure sealing and tighten the bolts as crosswise. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in line-mounting of valve. typical application 1 Isolation Valve (Gate, Butterfly Valve etc.) 2 Strainer 3 Proportional Pressure Reducing Valve 4 Air Valve 5 Quick Pressure Relief Valve 6 6 Pressure Reducing Valve
