Non thermally compensated, 2-way normally closed (NC) miniature proportional valve capable of 60 slpm flow and pressures up 50 psig. Ideal performance when utilized with closed loop control.

Product Information

The HF Pro is a miniature 2-way normally closed (NC) high flow proportional valve that controls gas flow proportionaly to input current with flow rates up to 60 slpm at 50 psig. The valve can be controlled with either DC current or pulse width modulation along with closed loop feedback to deliver optimal system performance. The HF Pro miniature proportional valve is an ideal choice for applications that require repeatable pressure and flow control such as respiratory and patient monitoring applications.
