Dimensions inch (mm) ( shown. See page 4 for all values) Additional height to e is.8 (1mm) when CPI 400 valve switch is mounted to valve. Functional description (Reference page ) The and series valves are automatic safety shutoff valves. The electromagnetic drive opens against the force of the closing spring 4. For the and series, the main flow through valve can be limited by the maximum flow adjustment 8. On the series, the hydraulic brake 10 permits slow opening. Initial lift can be adjusted 9. If power is interrupted (operating voltage), closing spring 4 closes the valve within 1 second. The valve position can be visually monitored by using the field installed visual indicator (VI) 1, or it can be visually and electronically monitored by a field installed CPI 400, which includes valve position indication lamps and one SPDT interlock switch 11 (order separately). V gas used = V Natural Gas x f f = correction factor to determine flow through valves with other gases. PRESSURE DROP FOR OTHER GASES To determine the pressure drop when using a gas other than natural gas, use the flow formula below and f value located in the chart below to determine the corrected flow rate in CFH through the valve for the other gas used. For example, when using propane, divide the volume (CFH) of propane required for the application by the calculated value f (f = 0.66 for propane). Use this corrected flow rate and the flow curve on the next page to determine pressure drop for propane.
