  7. Start up- Ooval 2 WAY (brass pilot) Pressure Reducing Valve Oz series model: OZ-RD2wm Make sure that there is flow and pressure through the pressure reducing valve, by opening any consumption downstream the PRV. Manually: To open the Ooval valve open isolation valves 5 and 6.. To close the Ooval valve closedownstream isolation valve 6. upstream isolation valve 5 should be open Automatic: make sure that isolation valves 5 & 6 are open. When the downstream pressure is lower than that of the pilot spring, the control chamber drains into the downstream and the valve opens. In this case there is a connection between port 3 (inlet upstream), port 1 or 2 (outlet downstream) and the control chamber. When the downstream pressure rises above the preset spring load, the pilot’s diaphragm is forced upwards closing port 1 or 2 (outlet downstream). The valve then begins closing and downstream pressure decreases. Close and open downstream consumption to ensure that the PRV reacts properly. Pilots ports 1 or 2 downstream/pressure gauge. 3 upstream (pressure) 4 control chamber. 2 3 1 OR 2 3 4 • Oz main valve • Metal pilot p-21(pressure reducing 2 way) • Needle valve / orifice (2 mm) • Mini control filter metal • Isolation valve • Isolation valve • Sleeve 7 6 1 4 5 OZ-QR PRESSURE FOR DRIPERS OZ-RD2WM TYPICAL INSTALLATION- Pressure Reducing 2 way PRESSURE FOR SPRINKLERS

  8. Start up- Ooval 2 WAY (brass pilot) Pressure Reducing with Electric Control Valve Oz series model: OZ-RDOE2WM Make sure that there is flow and pressure through the pressure reducing valve, by opening any consumption downstream to the PRV. Manual: in normal position the prv is close, To open the Ooval valve open isolation valves 5 and 6 and make sure that the solenoid is energized . To close the Ooval valve (solenoid is energized) close onlydownstream isolation valve 6. upstream isolation valve 5 should be open. Automatic: make sure that isolation valves 5 & 6 are open and the solenoid is energize . When the downstream pressure is lower than that of the pilot spring, the control chamber drains into the downstream and the valve opens. In this case there is a connection between port 3 (inlet upstream), port 1 or 2 (outlet downstream) and the control chamber. When the downstream pressure rises above the preset spring load, the pilot’s diaphragm is forced upwards and closes port 1 or 2 (outlet downstream). The valve then begins closing and downstream pressure decreases. Close and open downstream consumption to ensure that the PRV reacts properly.

  9. open Auto’ close Start up- Ooval 3 WAY (mini pilot) Pressure Reducing & sustaining with Electric Remote Control valve ,Oz series model: OZ-RSOE3WP Make sure that there is flow and pressure through the pressure reducing valve, by opening any consumption downstream the RSV. Check solenoid characteristics and ensure that it fits the electronic control system Manual: in normal position the RSV is closed. To open the Ooval valve use the three way selector to close or open by turning the handle to C(CLOSE) or O (open) , make sure that the solenoid is energized. The electric remote control enables to operate the Ooval valve in automatic reducing & sustaining mode Automatic: Position the three-way selector handle to A (automatic) and make sure that the solenoid is energized . When the upstream pressure is low, the pilot’s membrane is in its lowest position. The valve’s control chamber is exposed to line pressure through ports 2-3 of the pilot. The Ooval closes to sustain the upstream pressure. When the upstream pressure is higher than preset, it overcomes the pilot spring and forces the pilot diaphragm to move upwards. The connection between ports 3-4 opens and port 2 closes. The control chamber drains and the valve opens to relieve the excessive pressure downstream. In 3-way configurations, the control chamber drains out to atmosphere, permitting the valve to open entirely.
