Options and Accessories

The Pump Control Valve is designed to minimize the surges associated with the starting and stopping of pumps. The valve slowly opens and closes as required to control pumping related surges. The pump starts and stops against a closed valve.
Pump start up: When the pump is signaled to start, the 4-Way Solenoid is energized and directs fluid and pressure into the power chamber (below the diaphragm), and relieves fluid and pressure from the cover chamber (above the diaphragm). The fluid and pressure relieved from the cover chamber is vented to atmosphere or available floor drain. The valve opens at an adjustable rate, gradually admitting pumping pressure into the distribution system. Rate of valve opening is controlled by the adjustable opening speed control, which restricts the speed at which fluid and pressure evacuate the cover chamber. The valve remains fully open during the pumping cycle.
Pump shutdown: When the pump is signaled to shut-off, the 4-Way Solenoid is de-energized, and directs fluid and pressure into the cover chamber (above the diaphragm), and relieves fluid and pressure from the power chamber (below the diaphragm). The fluid and pressure relieved from the power chamber is vented to atmo- sphere or available floor drain. The valve closes at an adjustable rate, gradually reducing pumping pressure. Rate of valve closure is controlled by the adjustable closing speed control, which restricts the speed at which fluid and pressure evacuate the power chamber. When the valve reaches the closed position, the limit switch is actuated, turning the pump off.
Emergency Closure: The valve is equipped with a Mechanical Check Feature, which acts independent of diaphragm position, and provides immediate closure when flow ceases.
Manual Operation: Engaging the Solenoid Manual operator simulates power to the solenoid, manually opening the main valve. Disengaging the Solenoid Manual operator returns the valve to the closed position.

• Maximum continuous flow based on velocity of 20 ft. per second.

• Maximum intermittent flow based on velocity of 25 ft. per second.

• Minimum flow rates based on a 20-40 psi pressure drop.

• The Cv Factor of a value is the flow rate in US GPM at 60°F that will cause a 1psi drop in pressure.

• Cv factor can be used in the following equations to determine Flow (Q) and Pressure Drop (∆P):
  Q (Flow) = Cv√∆P ∆P (Pressure Drop) = (Q/Cv)²

• The Cv factors stated are based upon a fully open valve.

• Many factors should be considered in sizing control valves including inlet pressure, outlet pressure and flow rates.

• For sizing questions including cavitation analysis consult Watts with system details.

**Solenoid Action only. Main valve action (energize-to-open or energize-to- close) is dependent on the particulars of the pilot system.
***Brass solenoids are not lead free and it is illegal to use them in potable services in the United States such as drinking water, handwashing, food preparation, and dishwashing. However, brass solenoids may be used as a replacement component in a lead free Watts ACV main valve, as the wetted surface of a lead free Watts ACV main valve including installed brass solenoids contains less than 0.25% of lead by weight.

Model CK
Check Valve
Size: ¼” – 1″ NPT
** Model CK Check Valves are pilot line check valves. In typical applications these low cracking pressure in-line checks provide a hydraulic check feature to a pilot system. When the main valve outlet pressure exceeds inlet pressure, fluid is directed from the outlet to the main valve cover. This causes the main valve to close until inlet pressure is again greater than outlet.

Installation, Operation and Maintenance – Series LFM513-5 – Large

Installation

1. Prior to installation, flush line to remove debris.
2. Install valve so the flow arrow matches flow through the line, and gauges to monitor valve inlet and outlet pressures.
3. Install isolation valves upstream and downstream of the main valve.
4. Provide adequate clearance for valve servicing and maintenance. Refer to valve servicing dimensions on next page. Avoid installing valves 6″ and larger in the vertical position (main valve stem horizontal). Automatic Control Valves (ACVs) are designed for horizontal in-line installation, with the cover facing up (main valve stem vertical). Slow operation or premature stem and guide wear may occur if valve is not installed according to factory recommendations. Consult factory for detailed engineering review prior to ordering if valve is to be installed other than horizontally in-line.
5. If valve is equipped with a pilot control system, extra precautions should be made during installation to protect the piping circuit from damage. Only remove the pilot control system from the valve if necessary. Tubing and fittings should be kept clean and replaced exactly as removed. Consult appropriate hydraulic schematic to ensure proper re-assembly.
6. Connect solenoid wiring leads to desired switching device, using safe, standard electrical practices.
7. Wire the limit switch contacts to the proper relay connections, using safe, standard electrical practices. Adjust the limit switch collar to the approximate make/break contact position.

Valve Servicing Dimensions

The following tables detail the recommended minimum valve servicing dimensions.
