DEEP WELL PUMP (TURBINE TYPE)

Pump Control ValveModel C601/CF601

Typical Applications

BOOSTER PUMP (CENTRIFUGAL

BOOSTER PUMP (TURBINE TYPE)

The Model C601/CF601 Pump Control Valve protectsagainst downstream pressure surges by placing thepump on line slowly and taking it off line slowly. When the pump starts, a three-way solenoid valve is energized to open the Pump Control Valve at aslow, controlled rate by discharging control waterfrom above the diaphragm to waste through anadjustable needle valve.

To shut down the pump, the three-way solenoid valve is de-energized to introduce control water

above the diaphragm (through an adjustable needle valve) causing it to close slowly against the running pump.Just prior to full closure of the valve piston, the indicator rod opens a limit switch to stop the pump.

SIZING GUIDE for THROTTLING VALVES

In order to insure pressure control and avoid excessive noise and maintenance expense, extreme care must be takenwhen sizing the throttling valve for a specific application. Although both pressure conditions and flow (velocity) arecontributing factor, field experience has determined that flow rate is the most critical factor and that proper valve sizingcan be attained through consideration of the flow rate alone.

The maximum flow rates in tables below for Model C (Full ported valves) are based on a velocity of 15 ft per second,(fps) or 4.6 meter per second, (m/s). The throttling valve is capable of handling larger flows for short periods of time;however, the increase in maximum flow should be limited to 25% of the above values. Minimum flow rates are based on0.5 feet/second flow rate (0.15 meter per second, m/s). Valve should be selected to be opened between 20-80% for bestefficiencies and service life. The flow values for Model CF (Reduced ported valves) in the table below are less as theyhave smaller valve orifice or seat areas.

The tables below indicate the desired throttling valve size (inches) for designated maximum and minimum flow rates ingallons per minute (GPM):
