1021 Diaphragm Valve for Ivd Medical/Laboratory/Environmental Industry Application

1 .Production OverviewThe solenoid valve of 1021-2 way series is a family of diaphragm valve with 2mm orifice diameter, controlling the on/off of fluid flow path. This series solenoid valve is a high performance, low cost and maintenance free diaphragm valve with multiple model options, which are suitable for different reagents under different working conditions. Its life cycle can be operated more than 3 million.1.1 Characteristics Of 1021-2 SeriesOrifice diameter: 2mm; low resistance; Large flow: Cv≥0.05; flow≥8.5mL/s (pressure drop 50KPa, 25ºC, pure water)Small dead volume: zero dead volume inside the solenoid valve.Multiple option for wetted material:1. Body Material:POM,PVDF,PTFE.2. Seal Material:EPDM,FKM, FFKM.Long lifetime, high performance.  Respomse Time(T)Input air/water at 0.25MPa and maximum working pressure drop from inlet port, input rated control electrical signal to make the tested solenoid valve open and close, then we'll get the change of outlet pressure which we can measure from pressure sensor. At the same time, we'll get the lapse of time which starts from power on/off to rise to 90% of max pressure (normally closed valve) and drop to 10% of max pressure (normally open valve) by quick response time measure devise. Repeatedly test several times and take the average value as the power on response time and the power off response time.As engineering experience, it is the design critical value that response time above 50ms. The aspiration of valve may not stable. Therefore, the response time is not beyond 50ms within nominal lifetime.In addition, there is a response time at current method in this industry. The change of circuit leads to current change, according to the action of solenoid valve. The response time T1, T2 at current method is normally less than the response time(T) which measured by air flow method.  Seal CapabilityPressure strengthen (outside leakage).Solenoid valve powers on, the outlet is close, and the inlet water under condition of 5ºC~40ºC and 1.5 times of nominal pressure. Then ensure all connector won't leak within 1min.Sealing(inside leakage).For two normally closed branches, give one port pressures; put the other port into water. Under the nominal pressure, there is no bubble come out in 1min.Specification: Structure Direct acting poppet typeType2/2-way No.Of Ports 2Orifice Diameter 2.0mm Coefficient Of Variation (CV)  0.05MediumsWater, air, diluent, cleaning fluid, weak acid, weak base.Operating Temperature5ºC~50ºCOperating Pressure(in - out) -70 Kpa ~ 0.3 MPaLeakage Rate 0Response Time
