Drop a Rain Bird 100DV in line, wire it up to any standard 24 VAC sprinkler controller, and you’ve got a residential zone valve that’ll outlast the cheap plastic units on the shelf next to it. The DV series is Rain Bird’s workhorse for residential and light-commercial installs where city code calls for an upstream pressure vacuum breaker or double-check assembly — the valve handles the on/off, the backflow device handles the cross-connection protection. 1 in. NPT threaded inlet and outlet, glass-filled nylon body, 90-mesh self-cleaning filter, and a Buna-N diaphragm that takes municipal grit without tearing.

Why Irrigation Pros Pick the DV

• Universal compatibility — works with any 24 VAC residential or commercial sprinkler timer
• Self-cleaning 90 mesh (200 micron) inlet filter — cuts callbacks from grit-fouled diaphragms
• Buna-N diaphragm with reinforcement — resilient to chlorinated municipal water and minor sand load
• Internal and external manual bleed — flush the line during install, or trigger the zone without running back to the controller
• Captive plunger and spring — no parts to drop in the trench during a service call
• Latching solenoid compatible — swap in a Rain Bird latching solenoid to run on a battery-powered DC controller (TBOS-II, WPX, ESP-LXIVM)
• Reverse flow design — will not slam when pressurized backwards (handy on shared-manifold installs)
• Operates down to low-flow Xerigation rates when paired with a Rain Bird RBY filter upstream

Where It Shines

• Residential lawn and shrub-zone control in jurisdictions that require a separate PVB or DCVA
• Replacement for failed import valves on existing systems — same 1 in. NPT footprint
• Light commercial installs (HOA common areas, small parks, light-duty drip)
• Pump-fed systems — the DV handles surges that hammer cheaper valves to death

Install Notes

• Always wire the solenoid AFTER the controller is powered off — the DC pulse from a hot controller can latch the wrong state
• Pipe-thread sealant or Teflon tape is fine on the NPT inlet/outlet — the body is glass-filled nylon, no overtorque issues
• Mount with the flow-direction arrow pointed downstream
• For low-flow drip / Xerigation zones, add an RBY-100MX (1 in. wye filter) upstream to prevent diaphragm seat fouling at low velocities
• If the zone is on a battery controller (TBOS-II, WPX, ESP-LXIVM), order Rain Bird latching solenoid p/n DV-LATCH separately

What About the DVF (Flow Control)?

The 100DV is the standard model — full on/off only. The 100DVF model adds a manual flow-control stem on top so you can dial in the flow rate per zone (useful for matched-precip mixes or rotor zones that hammer). If you need flow control, ask us about the 100DVF.
