RDB series metal diaphragm pressure relief valves RDB metal diaphragm pressure relief valves have high flow (1.0 and 2.0Cv), high sensitivity and accuracy. Maximum import pressure: 500, 350 psig Outlet pressure range: 0~25, 0~50, 0~100, 0~150, 0~200psig Flow coefficient (Cv) : 1.0 (1/2 "ontology), 2.0 (3/4" ontology) Working temperature: - 40 ° C to 74 ° C - (40 ° F to 165 ° F) Leakage rate: inside: no gas leakage External: 2*10 atmosphere · ml/s helium (maximum internal leakage rate) Large diameter corrugated non-perforated diaphragm improves pressure sensitivity Metal to metal diaphragm seal Large flow, minimum pressure drop There is a filter screen inside Valve body port size: 1/2 "FNPT and 3/4" FNPT Select panel installation and bottom installation

RDE series plastic diaphragm pressure relief valves Maximum import pressure: 300psig Outlet pressure range: 0~25, 0~500 ~ 100, 0 ~ 150 psig Working temperature: - 23 ° CTo 74 ° c.(- 10 ° FTo 165 ° f.) Flow coefficient (Cv) : 10Leakage rate; Internal: no gas leakage Large diameter corrugated plastic film improves the pressure sensitivity Low pressure, high flow, minimum pressure drop Valve body interface size; Valve/relief valve Valve/relief valve RDF series bipolar metal diaphragm pressure relief valves Used for situations where the inlet pressure varies widely and the outlet requires constant pressure This secondary pressure regulating valve is equivalent to two primary pressure regulating valves in series. First class delivery When set to reduce the inlet pressure to 500psig(34.4bar). You can use the handle to adjust the second To obtain the required export pressure. This two-stage structure minimizes the reduction of gaseous steel Influence of inlet pressure fluctuation, such as gas depletion in bottle, on supply pressure effect. When import pressure drops to low At the first level of the set value, the pressure regulating valve will work as a first - level pressure regulating valve. Maximum import pressure: 3500psig Outlet pressure range: 0~25, 0 ~ 50, 0 ~ 100, 0 ~ 150, 0 ~ 250 psig Flow coefficient (Cv) : 0.06 Working temperature: - 40 ° CTo 74 °C(to 40 ° FTo 165 ° f.)
