PIBV2 Supervisory Switch

The PIBV2 supervisory switch monitors the open position of post indicator and butterfly control valves.

The PIBV2’s rugged housing is intended for indoor and outdoor use. When installed with the actuator in the vertical position, the PIBV2 is NEMA 3R rated per UL.

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

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 with a convenient breakaway feature for installation on shorter valves. This eliminates the need for cutting the shaft.

The PIBV2 has 100 percent synchronization which activates the alarm panel and local bell simultaneously. In addition, the switch is designed to operate in temperatures ranging from –40°C to 49°C (–40°F to 120°F). 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.
