PROPORTIONAL VALVES THAT HELP US BREATHE EASIER

With the onset of COVID-19, we as a company are dedicated to helping any and all ventilator or medical equipment manufacturers searching for flow control solutions that can quickly add to our respiratory care capacity in our community hospitals. We want to be a partner for you in our goal of healing our human community worldwide.

ENGINEERED FOR HIGH FLOW AND PRECISION

The current ventilator market demands higher flows at varying pressures, while not sacrificing performance.

 

This is where the versatile proportional valve offerings from iQ really differentiate themselves from the competition. iQ Valves has developed multiple pressure balanced designs which help maintain the precision flow and tight hysteresis that is currently being demanded for by the medical ventilator market.

 

These valves have undergone millions of cycles in life cycle testing, and are made from proprietary materials which enhance performance. Depending on the application, iQ has sealing methods that use either a compliant elastomeric seal or a hard seal which does not use any elastomer at all.

 

Our valves have been used in the industry since the late 1980s, and have only been improved in both design and manufacturing since.

DIFFERING VENTILATOR DESIGNS

Valve selection depends on input pressure and system design.

 

Due to the vast differences in approaches over the years when it comes to ventilator design, we have offered two proportional valve types to make sure flow requirements are met, while still keeping the overall footprint and cost in mind. Many ventilators will run off of an in room supply of both air and oxygen. This hospital supplied wall pressure can vary  based on location. With a fixed supply and varying inlet pressure range, we use our patented inlet pressure balancing technology to counteract any variances from hospital to hospital. These types of systems often use two proportional valves prior to blending that deliver optimal flow of around 150-180 slpm at around 25-35 psid. 

The second approach uses an air blower and oxygen supply being fed into a blender, which then moves downstream to a proportional valve at a much lower pressure. This valve faces two challenges: being able to deliver the flow with a much lower inlet pressure (eg. 1 psid), and being able to deal with any back pressure being created from the patient side downstream. The outlet pressure balancing of our PFCV allows us to address both issues while delivering premium flow performance.
