System Sensor’s PIBV2 supervisory switch monitors the open position of post indicator and butterfly control valves.

Robust Construction.
The PIBV2 consists of a rugged housing, intended for  indoor and outdoor use. When installed with the actuator in the vertical position, the PIBV2 is NEMA 3R rated per UL.

Application Flexibility.
The PIBV2 features a flexible design that accommodates  post indicator, butterfly, and many other types of wall post, recessed wall post  and pressure reducing valves. The PIBV2’s unique bi-directional actuator allows  the unit to be installed in either rising or falling flag installations.

Simplified Operation.
Installation is made easier with the PIBV2’s single side  conduit entrance. By providing a direct conduit pathway to the electrical  source, right angle fittings are not required. Installation is further simplified  by the PIBV2’s adjustable length actuator, which eliminates the need for cutting the shaft.

Reliable Performance.
The PIBV2 is equipped with tamper resistant cover  screws to prevent unauthorized entry. Inside, two sets of SPDT (Form C) synchronized switches are enclosed in a durable terminal block to assure reliable  performance.
