Product Overview
The 1224 series solenoid valve is a family of single channel pinch valves. This series solenoid valve is a high performance, low cost and maintenance free pinch valve with multiple model options, controlling the switch of flow path for different types of tube.
- Extended life cycle: More than 2 million operations.
- Hygienic Design: Tubing is simple and easy to clean, ideal for samples with impurities.
- Zero Contamination: Avoids cross-contamination among samples by keeping fluid within the tube.
- High Flow Capacity: ≥8.5mL/s (at 50KPa, 25ºC, pure water).
Technical Performance
Response time (T): Measured from power on/off to rise to 90% of max pressure (NC valve) or drop to 10% (NO valve). In engineering applications, a response time above 50ms may lead to unstable aspiration; therefore, the 1224 series ensures performance within this critical threshold.
Shut off pressure: When the normally open or normally closed solenoid valve is engaged, it supports silicon tubes (2.0x4.0mm, Shore 60) under 1.2 times nominal pressure water (5ºC~40ºC) for one minute without any liquid leakage.
Frequently Asked Questions
What is the estimated lifespan of the 1224 series pinch valve?
The 1224 series is designed for high durability, with a life cycle exceeding 2 million operations under standard conditions.
Does the fluid come into contact with the valve components?
No, the wetted material depends entirely on the silicon tube. The valve pinches the tube externally, preventing cross-contamination and making it ideal for medical and laboratory applications.
What type of tubing is recommended for this valve?
We recommend using silicon tubing with dimensions of 2mm x 4mm and a Shore hardness of 60 for optimal performance and shut-off capability.
What are the power requirements for the 1224-22 series?
The valve is available in 12V and 24V options, with power consumption of approximately 5.1W and 5.4W respectively.
Can this valve handle fluids containing particulate matter?
Yes, because it is a pinch valve with a straight-through flow path in the tube, it is highly suitable for applications where test samples contain impurities or particulate matters.
What is the maximum withstand pressure?
The normally open (1224-1) series can withstand -70KPa to 250KPa, while the normally closed (1224-2) series supports -70KPa to 150KPa.
