RDF Series bipolar metal diaphragm valve For import pressure change range is very large export need constant pressure of the occasion of this kind of two level pressure valve is equivalent to the two one level regulator series together. When the first factory is set to lower the inlet pressure to 500psig (34.4bar). You can use the handle to adjust the second level to get the required export pressure. This kind of two - level structure can reduce the influence of the pressure fluctuation on the pressure of the pressure fluctuation due to the depletion of gas in the gas cylinder. When the inlet pressure drops below the set value of the first level, the pressure valve will be used as a primary pressure relief valve.■ Maximum inlet pressure: 3500psig ■ outlet pressure range: 0~25, 0~50, 0~100, 0~150, 0~250psig ■ flow coefficient (Cv): 0.06 ■ working temperature: -40 degrees C to 74 degrees C (-40 DEG F to 165 DEG F) ■ Li: no internal leakage rate: gas leakage External: -8 2*10 - ml / sec helium (maximum internal leakage rate) ■ Corrugated perforated patch to ensure accurate pressure adjustment ■ metal on metal diaphragm seal ■ internal filter ■ Body size: 1/4 - Interface "FNPT ■ optional panel installation |
