<strong>Excess</strong> <strong>Flow</strong> <strong>Valves</strong><br />
EV Series<br />
Introduction<br />
If downstream line ruptures, the excess flow valve can stop uncontrolled release of system media. When the system is<br />
functioning normally, the working element remains in the open position. If the excess flow occurs downstream, the working<br />
element quickly moves to the tripped position to stop bleeding. When system pressure reaches balance through the bleed vent,<br />
the spring resets the working element to the open position automatically. The flow which goes through the bleed vent should<br />
be lower than one percent of the flow rate in the trip range.<br />
Features<br />
◎ Compact design for convenient installation<br />
◎ Working pressure up to: 6000 psig (414 bar)<br />
◎ Working temperature: -10F ° to 400° F (-23° C to 204°<br />
C)<br />
◎ Variety of end connections<br />
◎ Stainless steel construction<br />
◎ Leak-tight performance testing for every valve with<br />
nitrogen at the maximum working pressure<br />
End Connection:<br />
tube fitting, thread or<br />
face sealed<br />
◎ Easy installation<br />
◎ Improved system reliability<br />
Spring Drive to Brake<br />
◎ Easy operation<br />
◎ Enabled to work in any<br />
direction and improve<br />
the safety of system<br />
