Aircraft qualified
Compact design
Lightweight construction
Oxygen service to 2,000 psi

Features:
FRAME MODALITY: NEEDLE/DIAPHRAGM/FLAPPER/AXIAL/COUPLING
MEDIUM GAS: OXYGEN,NITROGEN, AIR . The single stage design, utilizing a Belleville and helical spring combination, results in an exceptionally compact unit. A Kel-F seat, metal sensing diaphragm, and inlet filter provide a high level of safety in high pressure oxygen environments. Over-pressure protection of the system downstream of the regulator is provided by a relief valve set at 140 ± 20 psig. A solid state pressure transducer mounted on the inlet side provides a 0-5 VDC signal for remote indication of oxygen supply pressure.

　The valve can be supplied with a fill/check valve for system charging. The valve incorporates a restrictor to limit the changing rate for temperature stabilization, and an automatic shutoff feature to limit system pressure to 2,000 psi .

This apparatus is connect with oxygen cylinder to save the sick and those who are lack of oxygen to inhale oxygen.
Main performances:
1) Flux regulation range: 0--10L/min.
2) Automatic exhaust pressure of safety valve: 0.35±0.05 MPa.
3) The apparatus is equipped with humidifier bottle that can be autoclavable at 120 degree Celsius
