Product Description
1. Production Overview
The solenoid valve of 1032-2 series is a family of diaphragm valve with 2.5mm orifice
diameter, controlling the switch 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 condition.The life cycle of
valves can be operated more than 2 million.
1.1. Characteristics Of 1032-2 Series
Orifice diameter: 2.5mm; small resistance along the way
Large flow: CV≥0.05;flow≥8.5mL/s(differential pressure 50KPa, 25ºC, pure water)
Small dead volume: zero dead volume inside the solenoid valve
Multiple option for wetted material:
1. Body material: PPS,POM,PVDF,PTFE etc.
2. Seal material: EPDM, FKM FFKM etc.
Long lifetime, high performance.
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. 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 valve 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
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 Capability
Pressure strengthen (outside leakage)
Solenoid valve powers on, the outlet is close, and the inlet water under condition of
5ºC~40ºCand 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 pressures; put the other port into
water. Under the nominal pressure, there is no bubble come out in 1min.
