Supervisory Switch

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

Robust Construction: 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.

Application Flexibility: 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 bi-directional actuator allows the unit to be installed in either rising or falling flag installations.

Simplified Installation: 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.

Reliable Performance: 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°F to 120°F (–40°C to 49°C). 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.
