PRESSURE REDUCING SERIES 127
THE OCV PRESSURE REDUCING VALVE IS USED TO REDUCE A GREATER UPSTREAM PRESSURE TO A LESSER, MORE MANAGABLE DOWNSTREAM PRESSURE, OPERATING WITHOUT REGARD TO EITHER UPSTREAM SUPPLY OR DOWNSTREAM DEMAND
PRESSURE RELIEF SERIES 108
THE OCV PRESSURE RELIEF VALVE IS USED TO MAINTAINS A CONSTANT INLET PRESSURE BY RELIEVING EXCESS HIGH PRESSURE |
| |
DIFFERENTIAL PRESSURE SERIES 110
THE OCV DIFFERENTIAL PRESSURE CONTROL VALVE IS DESIGND TO MAINTAIN A CONSTANT PRESSURE DIFFERENTIAL BETWEEN ANY TWO POINTS IN A SYSTEM WHERE THE CLOSING OF THE VALVE DIRECTLY CAUSES THE DIFFERENTIAL PRESSURE TO INCREASE |
| |
BOOSTER PUMP CONTROL VALVE SERIES 125
THE OCV SERIES 125 BOOSTER PUMP CONTROL VALVE IS FUNCTIONS TO MINIMIZE SURGES CAUSED BY THE START-UP AND SHUT DOWN OF THE PUMP, AND TO PROTECT FROM BACKFLOW IN THE EVENT OF POWER FAILURE |
| |
MODULATING CHECK VALVE SERIES 94
THE OCV SERIES 94 CHECK VALVE IS A SIMPLE ON-OFF VALVE THAT OPENS TO ALLOW FORWARD FLOW WHEN INLET PRESSURE EXCEEDS OUTLETAND CLOSES TIGHTLY TO PREVENT BACK FLOW |
| |
FLOAT CONTROL VALVE SERIES 8000
THE OCV SERIES 8000 ON-OFF TYPE AND SERIES 8100 MODULATING TYPE ARE DESIGNED TO MAINTAIN A DESIRED LEVEL IN A TANK OR RESERVOIR |
