DeltaPValve®
Commissioning Checklist
DeltaPValves do not need to be balanced; however, it is prudent after installation to commission the valves to ensure proper operation. This checklist does not apply to DeltaPValves installed in the central plant to control chiller flow.
- note the date (mm/dd/year)
- note the DeltaPValve serial number (on flow tag)
- verify valve is installed in the proper location (match flow tag to unit)
- verify valve is installed in the proper direction of flow (see arrow on casting)
- verify that balancing valves are not installed (preferred)
- verify isolation valves to the circuit are open
- when the valve is flowing, verify that minimum differential pressure is available measured across ports P1 and P3 (built into the valve) *
* minimum differential pressure (psid) REQUIRED during operation
- apply control signal (typically from air temperature thermostat) and verify that the actuator strokes
Notes: Direct proportional control (no derivative) is recommended for best performance - with a pneumatic actuator the stroke is set by the linkage (typically at the factory) - with an electronic actuator the stroke may be limited in the field by setting the span of the actuator control signal - full stroke will take between 60 seconds and 8 minutes depending on the actuator.
