System Sensor PIBV2 — supervisory switch that monitors the open position of post indicator and butterfly control valves.
A sprinkler control valve left closed disables every head downstream of it, and the closure is silent, so valve position is supervised, not inspected. The PIBV2 attaches through a 1/2" NPT nipple; its bi-directional actuator suits rising or falling flag installations and breaks away for shorter valves without cutting the shaft.
- Two sets of SPDT (Form C) synchronized switches, 10.0 A @ 125/250 V AC, 2.5 A @ 24 V DC
- Operates within two revolutions of the control, or before the flag moves a fifth of its travel
- Die-cast housing, UL certified for indoor or outdoor use; NEMA 3R with actuator vertical
- Operating temperature 32 °F to 120 °F (0 °C to 49 °C)
- One single-side 1/2" conduit entrance; accepts to 12 AWG
- 4 1/4" H × 3 1/2" W × 3 1/4" D; max stem extension 3 5/32"
The PIBV2A is the ULC model and includes the cover tamper switch as standard; on the UL model that switch is the optional 546-7000 kit. This device supervises valve position only — it is not a waterflow switch.

FAQ
Which valves does the PIBV2 supervise?
Post indicator and butterfly control valves, and many other types of wall post, recessed wall post and pressure reducing valves. The bi-directional actuator suits rising or falling flag installations.
How is it mounted?
In a 1/2 in. NPT tapped hole using the nipple. Acceptable positions are actuator vertical pointing down or actuator horizontal; actuator vertical pointing up is not acceptable.
What are the contact ratings?
Two sets of SPDT (Form C) contacts rated 10.0 A at 125/250 VAC and 2.5 A at 24 VDC. Terminals accept up to 12 AWG wire.
Is a cover tamper switch included?
It is standard on the ULC model PIBV2A. On the UL model PIBV2 it is optional, P/N 546-7000.
