Installation

Install the actuator

NOTICE:
To install an actuator on a valve already in line, close the shutoff valves (upstream first, then downstream) in the piping or turn off the pump. This procedure allows the differential pressure in the valve to drop.
1. Remove the protective cover from the valve stem.
2. Loosen knurled nut.
3. Set the required flow rate setting.
4. Retighten the knurled nut by hand.
5. Assemble actuator to valve and wire connections per actuator manufacturer's
instructions.

12 Ultra Setter™ Pressure Independent Control Valves Installation, Operation and Service Manual

Operation

Operate the valve

WARNING:
• Burn hazard. Water temperatures higher than 100°F (38°C) can be dangerous. Take all necessary precautions to prevent water or steam leakage.
• Hot water leakage can occur from readout valves during probe insertion and during hookup of readout kit. Follow the safety instructions supplied with readout probes and readout kits.
CAUTION:
Avoid pipe strain. This can cause breakage and water loss over time.
1. Ensure that the valve is fully open.
2. Using Bell & Gossett Model RP250–B Readout Probes, attach a Bell & Gossett
differential pressure readout kit to the readout valves on the desired valve.
3. Measure the pressure differential across the readout valves (P/T ports) in the valve
body, or in the valve body and through the valve handle. Confirm that the value obtained is greater than the minimum value indicated in the valve submittal. If it is not, then investigate the causes and if necessary, report to the designer.
4. Adjust the flow setting dial to the specified design flow rate. Lock the dial-in position
and record settings.
5. Repeat the process for all valves on the branch.
6. Measure the flow rate indicated at the flow measurement device on the branch.
Confirm that the value recorded is equal to the sum of the flows that are set at downstream valves. If it is not, then investigate the causes and if necessary, report to the designer.
When a flow measurement device is not present on the branch, measure the differential pressure across the valve and verify the minimum differential pressure listed in the submittal to achieve desired flow rate.
7. Repeat this procedure until all valves in the system have been set and their summated
flows checked against upstream flow measurement devices or differential pressure verification.
8. Measure the differential pressure across the valve on the system index terminal (usually
the most remote terminal from the pump). Adjust the pump speed until the pressure differential across this valve is equal to the minimum value indicated in the submittal.
9. Determine the pressure differential at the sensor location. Set the pump speed to
control such that the value indicated at the sensor is maintained constant under all conditions.
10. Measure and record the total flow rate, pressure differential, and energy consumption
at the pump.
11. Run all two port valves to their closed positions. Measure and record the total flow rate,
pressure differential, and energy consumption at the pump. Calculate and report the overall energy saving that is achieved between full load and minimum load operation.

Maintenance

Maintenance

Precautions

WARNING:
All procedures must be performed by qualified personnel.
When the process fluid is hazardous, thermal (hot or cold), or corrosive, take extra
precautions. Employ the appropriate safety devices and be prepared to control a process media leak.
Always wear protective clothing and equipment to safeguard the eyes, face, hands, skin, and lungs from the particular fluid in the line.

Valve inspection

Periodically inspect the valve for signs of leakage or corrosion.
WARNING:
Risk for property damage, serious personal injury or death. You must replace the valve if corrosion or leakage is found.

Service cartridge caps and drain caps

Any field adjustment of factory installed drain caps or cartridge caps affects the compression of the seal and can cause leakage. This adjustment necessitates the removal, cleaning, and resealing of those parts per the following instructions.
1. Remove the cap from the valve. Do not damage the valve, cap threads, or O-ring seal.
2. Perform the necessary service on the valve or system.
If the valve or any of the components appear to have been damaged, replace them.
3. Make sure that the male threads of the cap and the female threads of the valve are
clean and that there is no debris present.
4. Make sure that the O-ring seal is seated on the cartridge cap.
NOTICE:
Do not use any thread sealant or lubricant when assembling the cartridge or drain cap as it can prevent the O-ring seal from sealing properly.
5. Thread cap into the valve until it is finger tight.
6. Tighten cap to the following specification:
Component Seal Torque
Cartridge cap — all sizes O-ring 25.0 ft-lbs. + 7.0 ft-lbs. / 0
14 Ultra Setter™ Pressure Independent Control Valves Installation, Operation and Service Manual

Reseal the valve

The P/T readout ports and drain plugs come pre-assembled with a leading industrial thread sealant, Loctite, and are tightened to appropriate levels. Any field adjustment of factory installed components breaks the original thread seal and could cause leakage. This adjustment necessitates the removal, cleaning, and resealing of those parts per the following instructions.
1. Remove the desired component from the valve.
2. Clean off all of the old thread sealant using a wire brush and gentle abrasion if
necessary. If the component or valve appears to have been damaged, replace it.
3. Starting with the second thread of the NPT male valve component, apply a 360º bead
of Loctite 567 thread sealant/lubricant as shown. Follow Loctite handling precautions as noted on the product label.
Maintenance
4. If Loctite is not available, it is recommended that you use RectorSeal No. 5 pipe thread
sealant for all non-glycol based applications, or any PTFE thread sealing tape. Be sure to follow the manufacturer-specific handling precaution and application instructions as noted on the product label.
5. Thread component into the valve until it is finger tight.
6. Apply torque to the following specification:
Size Type Torque
1/4” NPT P/T Readout Port, drain plug 9.0 ft-lbs. + 3.0 ft-lbs. / 0
NOTICE:
The use of thread sealants and lubricants on threads also provides lubricity. Over­application of torque can damage to the valve port or component.
7. Properly assembled valve components will immediately seal to moderate pressure
(100 PSI or less). For maximum pressure resistance, allow the Loctite 567 or RectorSeal No. 5 thread sealant to cure for 24 hours. PTFE tape typically does not require curing to achieve maximum pressure resistance.
