PTFE Body and Diaphragm Isolated Solenoid Valve

1 Product OverviewThe 1012-2 Series solenoid valve is 1.5mm orifice diaphragm solenoid valve developed by Keyto independently, its mainly function is to switch on and off the liquid, be resistant to strong acid and alkali corrosion, high temperature and high pressure. This Series have 8Kg and 15Kgoption types, and they are suitable for different reagents in different condition. The life cycle ofvalves can be more than 2 millon times. It's a high precision, low cost and maintenance-free diaphragm solenoid valve.   1.1 Characteristics Of 1012-2 SeriesOrifice O.D.:1.5mm; Small resistance along the pathFlow capacity: Cv is about 0.03; Flow rate is about 5.1mL/s (Pressure differential 50Kpa,25ºC,pure water)Small dead volume: No dead volume inside the valve body;Multiple options for wetted materials:1. Material of valve body: Improved PTFE, PTFE2. Seal material: FFKM, FKMLong lifecycle, high performance,resistant to strong acid and alkali corrosion, hightemperature and high pressure Response 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, we'll get the lapse of timewhich 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 of5ºC~40ºC and nominal pressure is 1.5 times, then ensure all connector won't leak within 1min.Sealing(inside leakage).For two normally closed branches, give one port pressure; put the other port into water.Under the nominal pressure, there is no bubble come out in 1min.Product Features:Long life span; Anti-corrosion; Withstand high temperature and high pressure.Suitable for applying with air, water, some of the organic solvents in the environments of high temperature and high pressure.1012 Series Specification Structure Direct acting poppet type Valve type2/2-way, normally closed Port No.2 Orifice diameter1.5mmTubing specificationConnect the hose connector (according to the outer diameter of the pipe joint), or the pipe clamp connector (depending on the outer diameter of the pipe) Flow coefficient of valve (CV)0.03MediumsStrong acid, strong alkali, high temperature fluid, air, organic solvent, etc.Ambient temperature range5~40ºCWithstand pressure(in - out)0~0.8MPa0~1.5MPaLeakage rate0Response time
