Thermally compensated, 2-way normally closed (NC) proportional valve designed for flows up to 40 slpm. Ideal for respiratory and patient monitoring applications that require precise pressure and flow control.
Product Information
The VSO®- MI is a miniature proportional valve designed for medical equipment manufacturers. Based upon Parker Hannifin’s benchmark VSO® design, the VSO®- MI miniature proportional valve incorporates thermal compensation to provide precise flow control and stability over a wide range of media. Unlike competitive valves in its class, the VSO®- MI miniature proportional valve has been tested to U.S. Pharmacopoeia (USP) Class VI requirements making it easier to achieve system compliance for toxicity and sensitivity. With integrated filtration, captive O-rings, flush manifold mount capability, low power consumption and light weight, the VSO®- MI is an efficient miniature proportional valve ideally suited for manufacturers of portable and stationary medical equipment.- Thermally compensated to maintain precision flow and accuracy
- Tested to USP Class VI requirements to ease system compliance
- Proven performance tested to 25 million life cycles
- Integrated filters to protect the valve from damaging upstream and downstream particulates
- Cleaned for Oxygen Service Use
- RoHS compliant
Typical Applications:
- Ventilators
