This is a 5 Pack Rain Bird 100-DVF 1" Inlet Residential Sprinkler Valve w/Flow with BSP Threads.

Note, these have BPS threads. Not NPS-
NPT/NPS threads have a 60° angle and have flattened peaks and valleys where as BSP threads have a 55° angle and have rounded peaks and valleys.

In most situations that don’t involve high pressure, and irrigation is realitivly low pressure a male NPT fitting can be threaded into a female BSP fitting using Teflon tape to seal. Note that because the male NPT fitting is tapered it will thread a little farther into the straight threaded BSP female fitting.

1" 1" BSP Threaded in-line configuration

Unique, easy-to-turn patented pressure assisted flow control mechanism

Double-filtered pilot-flow design for maximum reliability

Balanced-pressure diaphragm for long life

External bleed to manually flush system of dirt and debris during installation and system start-up

Internal bleed for spray-free manual operation

Energy-efficient, low-power encapsulated solenoid with captured plunger and 90-mesh (200 micron) solenoid filter

 Note: These are individually boxed w/ the model number CPF100 on the box. For those who don’t know, the CPF100 & 100DVF are identical valves, and in fact the CPF100 has 100DVF stamped on the valve itself. The CPF100 is marketing as a retail product being sold in Home Depot, Lowes and Ace Hardware and for that reason they come in a retail ready box with easy-to-read instructions. The 100DVF is sold in specialty irrigation supply stores and is sold in a box of 20 in a plain brown box. Both valves are indeed the same. Rain bird does this with a lot of products. Like the Rainbird AG5 Maxi-Paw is the same as the 2045A Maxi-Paw and the Rainbird 42SA+ is the same as the 5004-PC3.0- In both these examples, one model is packaged for retail sale with colorful packing and the other is sold to irrigation specific stores, however both products are totally identical.
