VALVE CLOSED
When line pressure from the valve inlet is applied to the cover chamber, pressuring the diaphragm, the valve is closed drip-tight. |
|
VALVE OPEN
When diaphragm chamber pressure is vented the valve travels to the full open position. |
|
VALVE MODULATING
The valve is between full open and closed. The valve’s control pilot modulates the pressure in the diaphragm chamber, positioning the valve to control the desired pressure or flow. OCV pilot systems provide accurate control in a wide range of performance requirements. |
