Title:
Excess Flow Valves
EV41/EV45 Series
Used in cryogenic liquid cylinders or piping systems to prevent uncontrolled release of cryogenic fluid in the event of a rupture or abnormal excess of flow downstream of the pipeline.
Features
• Maximum working pressure: 580 psi (40 bar)
• Working temperature: -320~176oF (-196~80oC)
• Cleaned for oxygen service per CGA 4.1, suitable for use under pure oxygen environment

| Flow Options | Shut Off The Flow Value L/min | Pressure Difference psi(bar) | Min. Work Pressure psi(bar) |
| Standard Flow | 23.3 | 40 (2.8) | 80 (5.6) |
| Medium Flow | 15 | 40 (2.8) | 80 (5.6) |
| Low Flow | 10 | 14.5 (1) | 29 (2) |
Note: The product off the flow value is 15°C water test results
If the use of different media, the conversion of Q=Q1* V (P1/P)
(Q1 is water off the flow value, P1 for water density, Q for medium off flow value, P as medium density)
